CERTIFICATE VALIDATION

+ +

Summary of command line options:

+

The following options are used for certificate validation:

+
    +
  • The -cadir option specifies the directory where the Certificate +Authority (CA) certificates are stored. The default is platform specific, but +is usually "/etc/ssl/certs" on Linux/Unix systems. The default location can be +overridden via the SSL_CERT_DIR environment variable.
    • +
  • The -cafile option specifies the file that contains all of the +Certificate Authority (CA) certificates in the PEM file format. The default is +cert.pem, in the OpenSSL directory. On Linux/Unix systems, this is +usually "/etc/ssl/ca-bundle.pem". The default file can be overridden via the +SSL_CERT_FILE environment variable.
    • +
  • The -castore option contains the URI to the Certificate Authority +(CA) store, which may be a single container or a catalog of containers. +Starting with OpenSSL 3.2 on Windows, set this to "org.openssl.winstore://" to +use the built-in Windows Certificate Store. The Windows cert store only +supports root certificate stores.
    • +
  • The -request option is used to request the server send its +certificate chain as part of the connection negotiation process. This is +needed to do certificate validation. The default is true. In addition, the +client can manually inspect and accept or reject each certificate using the +-validatecommand option.
    • +
  • The -require option is used to require certificate validation be +performed as part of the connection negotiation process. A valid CA directory, +file, or store must be present for this to work.
    • +
+ +
+

When are command line options needed:

+

+By default, a client TLS connection does NOT validate the server certificate +chain. This limitation is due to the lack of a common cross platform +database of Certificate Authority (CA) provided certificates to validate +against. Many Linux systems natively support OpenSSL and thus have these +certificates installed as part of the OS, but MacOS and Windows do not. In +order to use the -require option, one of the following must be true:

+
    +
  • On Linux and Unix systems with OpenSSL already installed, if the CA +certificates are stored in the standard locations, or the SSL_CERT_DIR +or SSL_CERT_FILE env vars are set, then no other options are needed.
    • + +
  • If OpenSSL is not installed in the default location, or when using Mac OS +or Windows and OpenSSL is installed, the SSL_CERT_DIR and/or +SSL_CERT_FILE env vars or the -cadir and/or -cafile + options must be defined.
    • + +
  • On Windows, starting in OpenSSL 3.2, it is now possible to access the +built-in Windows Certificate Store from OpenSSL. This can be achieved by +setting the -castore option to "org.openssl.winstore://".
    • + +
  • If OpenSSL is not installed, the CA certificates must be downloaded and +installed with the user software. The CURL team makes them available at +CA certificates extracted +from Mozilla in the cacert.pem file. You must then either +set the SSL_CERT_DIR and/or SSL_CERT_FILE env vars or the +-cadir or -cafile options must be set to the file's install +location. It is your responsibility to keep this file up to date.
    • +
+
+ +

CALLBACK OPTIONS

As indicated above, individual channels can be given their own callbacks to handle intermediate processing by the OpenSSL library, using the -command, -password, and -validate_command options passed to either of tls::socket or tls::import. -If the callback generates an error, the bgerror command will be -invoked with the error information. +Unlike previous versions of TCL TLS, only if the callback generates an error, +will the bgerror command will be invoked with the error information.

-

-# Nmake is a pretty weak environment in syntax and capabilities
-# so this file is necessarily verbose. It's broken down into
-# the following parts.
-#
-# 0. Sanity check that compiler environment is set up and initialize
-#    any built-in settings from the parent makefile
-# 1. First define the external tools used for compiling, copying etc.
-#    as this is independent of everything else.
-# 2. Figure out our build structure in terms of the directory, whether
-#    we are building Tcl or an extension, etc.
-# 3. Determine the compiler and linker versions
-# 4. Build the nmakehlp helper application
-# 5. Determine the supported compiler options and features
-# 6. Extract Tcl, Tk, and possibly extensions, version numbers from the
-#    headers
-# 7. Parse the OPTS macro value for user-specified build configuration
-# 8. Parse the STATS macro value for statistics instrumentation
-# 9. Parse the CHECKS macro for additional compilation checks
-# 10. Based on this selected configuration, construct the output
-#     directory and file paths
-# 11. Construct the paths where the package is to be installed
-# 12. Set up the actual options passed to compiler and linker based
-#     on the information gathered above.
-# 13. Define some standard build targets and implicit rules. These may
-#     be optionally disabled by the parent makefile.
-# 14. (For extensions only.) Compare the configuration of the target
-#     Tcl and the extensions and warn against discrepancies.
-#
-# One final note about the macro names used. They are as they are
-# for historical reasons. We would like legacy extensions to
-# continue to work with this make include file so be wary of
-# changing them for consistency or clarity.

-# 10. Construct output directory and file paths
-# Figure-out how to name our intermediate and output directories.
-# In order to avoid inadvertent mixing of object files built using
-# different compilers, build configurations etc.,
-#
-# Naming convention (suffixes):
-#   t = full thread support. (Not used for Tcl >= 8.7)
-#   s = static library (as opposed to an import library)
-#   g = linked to the debug enabled C run-time.
-#   x = special static build when it links to the dynamic C run-time.
-#
-# The following macros are set in this section:
-# SUFX - the suffix to use for binaries based on above naming convention
-# BUILDDIRTOP - the toplevel default output directory
-#      is of the form {Release,Debug}[_AMD64][_COMPILERVERSION]
-# TMP_DIR - directory where object files are created
-# OUT_DIR - directory where output executables are created
-# Both TMP_DIR and OUT_DIR are defaulted only if not defined by the
-# parent makefile (or command line). The default values are
-# based on BUILDDIRTOP.
-# STUBPREFIX - name of the stubs library for this project
-# PRJIMPLIB - output path of the generated project import library
-# PRJLIBNAME - name of generated project library
-# PRJLIB     - output path of generated project library
-# PRJSTUBLIBNAME - name of the generated project stubs library
-# PRJSTUBLIB - output path of the generated project stubs library

+#    headers
+# 7. Parse the OPTS macro value for user-specified build configuration
+# 8. Parse the STATS macro value for statistics instrumentation
+# 9. Parse the CHECKS macro for additional compilation checks
+# 10. Based on this selected configuration, construct the output
