20:01
Created DH branch check-in: 22f9df2429 user: bohagan tags: dh
2023-12-25
02:04
Added KDF test cases check-in: 4cc32676a2 user: bohagan tags: crypto
2023-12-24
22:57
Moved common get cipher, digest, etc. functions to tlsUtil.c file. Renamed tlsKey.c to tlsKDF.c to better reflect contents. Standardized error messages. check-in: 94f8408d0d user: bohagan tags: crypto

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

<p>
The <strong>tls::debug</strong> 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 <strong>tls::callback</strong> to accept the
certificate, even when it is invalid.
</p>

<p>
<em>
The use of the reference callbacks <strong>tls::callback</strong>,
<strong>tls::password</strong>, and <strong>tls::validate_command</strong>
is not recommended.  They may be removed from future releases.

<h3><a name="DEBUG">DEBUG</a></h3>

TLS key logging can be enabled by setting the environment variable
<b>SSLKEYLOGFILE</b> 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. This
is useful for logging key data for network logging tools to use to
decrypt the data.
