This extension provides a generic binding to Server cache mode (client, server, or both).
tls::ciphers
- protocol ?verbose? ?supported?
- Returns a list of supported ciphers available for protocol,
- where protocol must be one of ssl2, ssl3, tls1, tls1.1,
- tls1.2, or tls1.3. If verbose is specified as
- true then a verbose, human readable list is returned with
- additional information on the cipher. If supported
+ ?protocol? ?verbose? ?supported?
+
Without any args, returns a list of all ciphers. With
+ protocol, only the ciphers supported for that protocol
+ are returned where protocol must be one of ssl2, ssl3,
+ tls1, tls1.1, tls1.2, or tls1.3. If verbose is
+ specified as true then a verbose, human readable list is returned
+ with additional information on the cipher. If supported
is specified as true, then only the ciphers supported for protocol
will be listed.
+
+ tls::digests
+ Returns a list of the hash algorithms for tls::digest command.
+
+ tls::macs
+ Returns a list of the available Message Authentication Codes (MAC) for
+ the tls::digest command.
tls::protocols
Returns a list of supported protocols. Valid values are:
ssl2, ssl3, tls1, tls1.1, tls1.2,
and tls1.3. Exact list depends on OpenSSL version and
compile time flags.
tls::version
Returns the OpenSSL version string.
+
+
+ tls::digest digest ?-bin|-hex?
+ [-file filename | -command cmdName | -chan channelId | ?-data? data]
+ Calculate the message digest for data using digest hash
+ function. Returns value as a hex string (default) or as a binary value
+ with -bin option. Argument digest can be any OpenSSL
+ supported hash function including: md4, md5, sha1,
+ sha256, sha512, sha3-256, etc. See
+ tls::digests command for a full list.
+
+ Using the -data option will immediately return the message
+ digest for data in the specified format.
+
+ Using the -file option will open file filename, read
+ the file data, close the file, and return the message digest in the
+ specified format. This uses the TCL APIs, so VFS files are supported.
+
+ Using the -chan option, a stacked channel is created for
+ channelId and data read from the channel is used to calculate
+ a message digest with the result returned with the last read operation
+ before EOF. Channel is automatically set to binary mode.
+
+ Using the -command option, a new command cmdName is
+ created and returned. To add data to the hash function, call
+ "cmdName update data", where data is
+ the data to add. When done, call "cmdName finalize"
+ to return the message digest.
+
+
+ tls::cmac digest
+ -cipher name ?-bin|-hex? [-file filename |
+ -command cmdName | -chan channelId | ?-data? data]
+ Calculate the Cipher-based Message Authentication Code (CMAC). Same arguments
+ as tls::digest with additional option -cipher to specify the
+ cipher to use and for certain ciphers, -key to specify the key.
+
+ tls::hmac digest
+ -key key ?-bin|-hex? [-file filename |
+ -command cmdName | -chan channelId | ?-data? data]
+ Calculate the Hashed Message Authentication Code (HMAC). Same arguments
+ as tls::digest with additional option -key to specify the
+ key to use. To salt a password, append or prepend the salt
+ data to the password.
+
+ tls::md4 data
+ Returns the MD4 message-digest for data as a hex string.
+
+ tls::md5 data
+ Returns the MD5 message-digest for data as a hex string.
+
+ tls::sha1 data
+ Returns the SHA1 secure hash algorithm digest for data as a hex string.
+
+ tls::sha256 data
+ Returns the SHA-2 SHA256 secure hash algorithm digest for data as a hex string.
+
+ tls::sha512 data
+ Returns the SHA-2 SHA512 secure hash algorithm digest for data as a hex string.
