DESCRIPTION

+ +

This extension provides a generic binding to OpenSSL, utilizing the +Tcl_StackChannel +API for Tcl 8.4 and higher. The sockets behave exactly the same +as channels created using Tcl's built-in socket +command with additional options for controlling the SSL session. +

+ +

COMMANDS

+ +

Typically one would use the tls::socket command +which provides compatibility with the native Tcl socket +command. In such cases tls::import should not be +used directly.

+ +
+
tls::init ?options?
+
This routine sets the default options used by tls::socket + and is optional. If you call tls::import + directly this routine has no effect. Any of the options + that tls::socket accepts can be set + using this command, though you should limit your options + to only TLS related ones.
+
 
+
tls::socket ?options? + host port
+
tls::socket ?-server command? ?options? port
+
This is a helper function that utilizes the underlying + commands (tls::import). It behaves + exactly the same as the native Tcl socket + command except that the options can include any of the + applicable tls:import + options with one additional option: +
+
+
-autoservername bool
+
Automatically send the -servername as the host argument + (default: false)
+
+
+
 
+
tls::handshake channel
+
Forces handshake to take place, and returns 0 if + handshake is still in progress (non-blocking), or 1 if + the handshake was successful. If the handshake failed + this routine will throw an error.
+
 
+
tls::status + ?-local? channel
+
Returns the current security status of an SSL channel. The + result is a list of key-value pairs describing the + connected peer. If the result is an empty list then the + SSL handshake has not yet completed. + If -local is given, then the certificate information + is the one used locally.
+
+ +
+
+
issuer dn
+
The distinguished name (DN) of the certificate + issuer.
+
subject dn
+
The distinguished name (DN) of the certificate + subject.
+
notBefore date
+
The begin date for the validity of the certificate.
+
notAfter date
+
The expiry date for the certificate.
+
serial n
+
The serial number of the certificate.
+
cipher cipher
+
The current cipher in use between the client and + server channels.
+
sbits n
+
The number of bits used for the session key.
+
certificate cert
+
The PEM encoded certificate.
+
sha1_hash hash
+
The SHA1 hash of the certificate.
+
sha256_hash hash
+
The SHA256 hash of the certificate.
+
alpn protocol
+
The protocol selected after Application-Layer Protocol + Negotiation (ALPN).
+
version value
+
The protocol version used for the connection: + SSLv2, SSLv3, TLSv1, TLSv1.1, TLSv1.2, TLSv1.3, unknown
+
+
+ +
+
tls::import channel + ?options?
+
SSL-enable a regular Tcl channel - it need not be a + socket, but must provide bi-directional flow. Also + setting session parameters for SSL handshake.
+
+ +
+
+
-alpn list
+
List of protocols to offer during Application-Layer + Protocol Negotiation (ALPN). For example: h2, http/1.1, etc.
+
-cadir dir
+
Provide the directory containing the CA certificates. The + default directory is platform specific and can be set at + compile time. This can be overridden via the SSL_CERT_DIR + environment variable.
+
-cafile filename
+
Provide the CA file.
+
-certfile filename
+
Provide the name of a file containing certificate to use. + The default name is cert.pem. This can be overridden via the + SSL_CERT_FILE environment variable.
+
-cert filename
+
Provide the contents of a certificate to use, as a DER encoded binary value (X.509 DER).
+
-cipher string
+
Provide the cipher suites to use. Syntax is as per + OpenSSL.
+
-command callback
+
If specified, this callback will be invoked at several points + during the OpenSSL handshake. It can pass errors and tracing + information, and it can allow Tcl scripts to perform + their own validation of the certificate in place of the + default validation provided by OpenSSL. +
+ See CALLBACK OPTIONS for + further discussion.
+
-dhparams filename
+
Provide a Diffie-Hellman parameters file.
+
-keyfile filename
+
Provide the private key file. (default: + value of -certfile)
+
-key filename
+
Provide the private key to use as a DER encoded value (PKCS#1 DER)
+
-model channel
+
This will force this channel to share the same SSL_CTX + structure as the specified channel, and + therefore share callbacks etc.
+
-password callback
+
If supplied, this callback will be invoked when OpenSSL needs + to obtain a password, typically to unlock the private key of + a certificate. + The callback should return a string which represents the + password to be used. +
+ See CALLBACK OPTIONS for + further discussion.
+
-request bool
+
Request a certificate from peer during SSL handshake. + (default: true)
+
-require bool
+
Require a valid certificate from peer during SSL + handshake. If this is set to true then -request + must also be set to true. (default: false)
+
-server bool
+
Handshake as server if true, else handshake as + client.(default: false)
+
-servername host
+
Only available if the OpenSSL library the package is linked + against supports the TLS hostname extension for 'Server Name + Indication' (SNI). Use to name the logical host we are talking + to and expecting a certificate for
+
-ssl2 bool
+
Enable use of SSL v2. (default: false)
+
-ssl3 bool
+
Enable use of SSL v3. (default: false)
+
-tls1 bool
+
Enable use of TLS v1. (default: true)
+
-tls1.1 bool
+
Enable use of TLS v1.1 (default: true)
+
-tls1.2 bool
+
Enable use of TLS v1.2 (default: true)
+
-tls1.3 bool
+
Enable use of TLS v1.3 (default: true)
+
+
+ +
+
tls::unimport channel
+
Provided for symmetry to tls::import, this + unstacks the SSL-enabling of a regular Tcl channel. An error + is thrown if TLS is not the top stacked channel type.
+
+ +
+
tls::ciphers + protocol ?verbose?
+
Returns list of supported ciphers based on the protocol + you supply, which must be one of ssl2, ssl3, or tls1. + If verbose is specified as true then a verbose, + semi-human readable list is returned providing additional + information on the nature of the cipher support. In each + case the result is a Tcl list.
+
+ +
+
tls::version
+
Returns the version string defined by OpenSSL.
+
+ +

CALLBACK OPTIONS

+ +

+As indicated above, individual channels can be given their own callbacks +to handle intermediate processing by the OpenSSL library, using the +-command and -password options passed to either of +tls::socket or tls::import. +

+ +
+
+ +
-command callback
+
+ Invokes the specified callback script at + several points during the OpenSSL handshake. + Except as indicated below, values returned from the + callback are ignored. + Arguments appended to the script upon callback take one of the + following forms: + +
+
+ +
+ + + +
+ info channel major minor message +
+
+ This form of callback is invoked by the OpenSSL function + SSL_CTX_set_info_callback(). +
+ The major and minor arguments are used to + represent the state information bitmask. +
+
Possible values for major are:
+
handshake, alert, connect, accept.
+
Possible values for minor are:
+
start, done, read, write, loop, exit.
+
+ The message argument is a descriptive string which may + be generated either by + SSL_state_string_long() or by + SSL_alert_desc_string_long(), + depending on context. +
+ +
+ +
+ verify channel depth cert status error +
+
+ This form of callback is invoked by the OpenSSL function + SSL_set_verify(). +
+ The depth argument is an integer representing the + current depth on the certificate chain, with + 0 as the subject certificate and higher values + denoting progressively more indirect issuer certificates. +
+ The cert argument is a list of key-value pairs similar + to those returned by + tls::status. +
+ The status argument is an integer representing the + current validity of the certificate. + A value of 0 means the certificate is deemed invalid. + A value of 1 means the certificate is deemed valid. +
+ The error argument supplies the message, if any, generated + by + X509_STORE_CTX_get_error(). +
+
+ The callback may override normal validation processing by explicitly + returning one of the above status values. +
+ +
+
+ +
+ +
-password callback
+
+ Invokes the specified callback script when OpenSSL needs to + obtain a password. The callback should return a string which + represents the password to be used. + No arguments are appended to the script upon callback. +
+
+
+ +

+Reference implementations of these callbacks are provided in the +distribution as tls::callback and +tls::password respectively. Note that these are +sample implementations only. In a more realistic deployment +you would specify your own callback scripts on each TLS channel +using the -command and -password options. +

+ +

+The default behavior when the -command option is not specified is for +TLS to process the associated library callbacks internally. +The default behavior when the -password option is not specified is for +TLS to process the associated library callbacks by attempting to call +tls::password. +The difference between these two behaviors is a consequence of maintaining +compatibility with earlier implementations. +

+ +

+The tls::debug variable provides some additional +control over these reference callbacks. Its value is zero by default. +Higher values produce more diagnostic output, and will also force the +verify method in tls::callback to accept the +certificate, even when it is invalid. +

+ +

+ +The use of the reference callbacks tls::callback and +tls::password is not recommended. They may be removed +from future releases. + +

+ +

+ +The use of the variable tls::debug is not recommended. +It may be removed from future releases. + +

+ +

DEBUG

+ +TLS key logging can be enabled by setting the environment variable +SSLKEYLOGFILE to the name of the file to log to. Then whenever TLS +key material is generated or received it will be logged to the file. + +

HTTPS EXAMPLE

+ +

This example uses a sample server.pem provided with the TLS release, +courtesy of the OpenSSL project.

+ +

+package require http
+package require tls
+
+http::register https 443 [list ::tls::socket -autoservername true -require true -cadir /etc/ssl/certs]
+
+set tok [http::geturl https://www.tcl.tk/]
+
+ +

SPECIAL CONSIDERATIONS

+ +

The capabilities of this package can vary enormously based +upon how your OpenSSL library was configured and built. At the +most macro-level OpenSSL supports a "no patents" build, +which disables RSA, IDEA, RC(2,4,5) and SSL2 - if your OpenSSL is +configured this way then you will need to build TLS with the +-DNO_PATENTS option - and the resultant module will function +correctly and also support ADH certificate-less encryption, +however you will be unable to utilize this to speak to normal Web +Servers, which typically require RSA support. Please see http://www.openssl.org/ for +more information on the whole issue of patents and US export +restrictions.

DESCRIPTION

- -

This extension provides a generic binding to OpenSSL, utilizing the -Tcl_StackChannel -API for Tcl 8.4 and higher. The sockets behave exactly the same -as channels created using Tcl's built-in socket -command with additional options for controlling the SSL session. -

- -

COMMANDS

- -

Typically one would use the tls::socket command -which provides compatibility with the native Tcl socket -command. In such cases tls::import should not be -used directly.

- -
-
tls::init ?options?
-
This routine sets the default options used by tls::socket - and is optional. If you call tls::import - directly this routine has no effect. Any of the options - that tls::socket accepts can be set - using this command, though you should limit your options - to only TLS related ones.
-
 
-
tls::socket ?options? - host port
-
tls::socket ?-server command? ?options? port
-
This is a helper function that utilizes the underlying - commands (tls::import). It behaves - exactly the same as the native Tcl socket - command except that the options can include any of the - applicable tls:import - options with one additional option: -
-
-
-autoservername bool
-
Automatically send the -servername as the host argument - (default: false)
-
-
-
 
-
tls::handshake channel
-
Forces handshake to take place, and returns 0 if - handshake is still in progress (non-blocking), or 1 if - the handshake was successful. If the handshake failed - this routine will throw an error.
-
 
-
tls::status - ?-local? channel
-
Returns the current security status of an SSL channel. The - result is a list of key-value pairs describing the - connected peer. If the result is an empty list then the - SSL handshake has not yet completed. - If -local is given, then the certificate information - is the one used locally.
-
- -
-
-
issuer dn
-
The distinguished name (DN) of the certificate - issuer.
-
subject dn
-
The distinguished name (DN) of the certificate - subject.

-
notAfter date
-
The expiry date for the certificate.
-
serial n
-
The serial number of the certificate.

-
version value
-
The protocol version used for the connection: - SSLv2, SSLv3, TLSv1, TLSv1.1, TLSv1.2, TLSv1.3, unknown
-
-
- -
-
tls::import channel - ?options?
-

-
- -
-
-
-alpn list
-
List of protocols to offer during Application-Layer - Protocol Negotiation (ALPN). For example: h2, http/1.1, etc.
-
-cadir dir

-
-certfile filename
-
Provide the name of a file containing certificate to use. - The default name is cert.pem. This can be overridden via the - SSL_CERT_FILE environment variable.
-
-cert filename
-
Provide the contents of a certificate to use, as a DER encoded binary value (X.509 DER).
-
-cipher string
-
Provide the cipher suites to use. Syntax is as per - OpenSSL.
-
-command callback
-
If specified, this callback will be invoked at several points - during the OpenSSL handshake. It can pass errors and tracing - information, and it can allow Tcl scripts to perform - their own validation of the certificate in place of the - default validation provided by OpenSSL. -
- See CALLBACK OPTIONS for - further discussion.
-
-dhparams filename
-
Provide a Diffie-Hellman parameters file.
-

-
-model channel
-
This will force this channel to share the same SSL_CTX - structure as the specified channel, and - therefore share callbacks etc.
-
-password callback
-
If supplied, this callback will be invoked when OpenSSL needs - to obtain a password, typically to unlock the private key of - a certificate. - The callback should return a string which represents the - password to be used. -
- See CALLBACK OPTIONS for - further discussion.
-
-request bool
-
Request a certificate from peer during SSL handshake. - (default: true)
-
-require bool
-
Require a valid certificate from peer during SSL - handshake. If this is set to true then -request - must also be set to true. (default: false)
-
-server bool
-
Handshake as server if true, else handshake as - client.(default: false)
-
-servername host

-
-tls1.2 bool
-
Enable use of TLS v1.2 (default: true)
-
-tls1.3 bool
-
Enable use of TLS v1.3 (default: true)
-
-
- -
-
tls::unimport channel
-
Provided for symmetry to tls::import, this - unstacks the SSL-enabling of a regular Tcl channel. An error - is thrown if TLS is not the top stacked channel type.
-
- -
-
tls::ciphers - protocol ?verbose?
-
Returns list of supported ciphers based on the protocol - you supply, which must be one of ssl2, ssl3, or tls1. - If verbose is specified as true then a verbose, - semi-human readable list is returned providing additional - information on the nature of the cipher support. In each - case the result is a Tcl list.
-
- -
-
tls::version
-
Returns the version string defined by OpenSSL.
-
- -

CALLBACK OPTIONS

- -

-As indicated above, individual channels can be given their own callbacks -to handle intermediate processing by the OpenSSL library, using the --command and -password options passed to either of -tls::socket or tls::import. -

- -
-
- -
-command callback
-
- Invokes the specified callback script at - several points during the OpenSSL handshake. - Except as indicated below, values returned from the - callback are ignored. - Arguments appended to the script upon callback take one of the - following forms: - -
-
- -
- - - -
- info channel major minor message -
-
- This form of callback is invoked by the OpenSSL function - SSL_CTX_set_info_callback(). -
- The major and minor arguments are used to - represent the state information bitmask. -
-
Possible values for major are:
-
handshake, alert, connect, accept.
-
Possible values for minor are:
-
start, done, read, write, loop, exit.
-
- The message argument is a descriptive string which may - be generated either by - SSL_state_string_long() or by - SSL_alert_desc_string_long(), - depending on context. -
- -
- -
- verify channel depth cert status error -
-
- This form of callback is invoked by the OpenSSL function - SSL_set_verify(). -
- The depth argument is an integer representing the - current depth on the certificate chain, with - 0 as the subject certificate and higher values - denoting progressively more indirect issuer certificates. -
- The cert argument is a list of key-value pairs similar - to those returned by - tls::status. -
- The status argument is an integer representing the - current validity of the certificate. - A value of 0 means the certificate is deemed invalid. - A value of 1 means the certificate is deemed valid. -
- The error argument supplies the message, if any, generated - by - X509_STORE_CTX_get_error(). -
-
- The callback may override normal validation processing by explicitly - returning one of the above status values. -
- -
-
- -
- -
-password callback
-
- Invokes the specified callback script when OpenSSL needs to - obtain a password. The callback should return a string which - represents the password to be used. - No arguments are appended to the script upon callback. -
-
-
- -

-Reference implementations of these callbacks are provided in the -distribution as tls::callback and -tls::password respectively. Note that these are -sample implementations only. In a more realistic deployment -you would specify your own callback scripts on each TLS channel -using the -command and -password options. -

- -

-The default behavior when the -command option is not specified is for -TLS to process the associated library callbacks internally. -The default behavior when the -password option is not specified is for -TLS to process the associated library callbacks by attempting to call -tls::password. -The difference between these two behaviors is a consequence of maintaining -compatibility with earlier implementations. -

- -

-The tls::debug variable provides some additional -control over these reference callbacks. Its value is zero by default. -Higher values produce more diagnostic output, and will also force the -verify method in tls::callback to accept the -certificate, even when it is invalid. -

- -

- -The use of the reference callbacks tls::callback and -tls::password is not recommended. They may be removed -from future releases. - -

- -

- -The use of the variable tls::debug is not recommended. -It may be removed from future releases. - -

- -

DEBUG

- -TLS key logging can be enabled by setting the environment variable -SSLKEYLOGFILE to the name of the file to log to. Then whenever TLS -key material is generated or received it will be logged to the file. - -

HTTPS EXAMPLE

- -

This example uses a sample server.pem provided with the TLS release, -courtesy of the OpenSSL project.

- -

-package require http
-package require tls
-
-http::register https 443 [list ::tls::socket -autoservername true -require true -cadir /etc/ssl/certs]
-
-set tok [http::geturl https://www.tcl.tk/]
-
- -

SPECIAL CONSIDERATIONS

- -

The capabilities of this package can vary enormously based -upon how your OpenSSL library was configured and built. At the -most macro-level OpenSSL supports a "no patents" build, -which disables RSA, IDEA, RC(2,4,5) and SSL2 - if your OpenSSL is -configured this way then you will need to build TLS with the --DNO_PATENTS option - and the resultant module will function -correctly and also support ADH certificate-less encryption, -however you will be unable to utilize this to speak to normal Web -Servers, which typically require RSA support. Please see http://www.openssl.org/ for -more information on the whole issue of patents and US export -restrictions.
