Here is a revision that creates a mapping file (similar to mapping.txt, but that mirrors the formatting of "$OPENSSL ciphers -V" and that includes all cipher suites, even ones for which there is no OpenSSL name), loads the contents of the file into arrays, and then uses the arrays to implement openssl2rfc() and rfc2openssl().
This PR provides implementations of openssl2rfc and rfc2openssl. It also uses openssl2rfc() in run_server_preference() to help determine how to display the "negotiated cipher." I believe that using the RFC names addresses the current FIXME:
FIXME BEAST: We miss some CBC ciphers here, need to work w/ a list"
Since some OpenSSL binaries, namely Gentoo’s, don’t support bracketed
IPv6 addresses but unbracketed ones, specified as the -connect option,
the UNBRACKETED_IPV6 environment variable can be set to true for
disabling the automatic addition of brackets around IPv6 addresses on
such platforms.
While standard OpenSSL requires the literal IPv6 address enclosed
in [brackets], standard DNS lookup tools don’t support the additional
characters. Before making reverse PTR lookups, these brackets have to
be removed from the IPv6 addresses.
When run_rc4() is run with the "--show-each" option, but without the "--wide" option, a list of all RC4 ciphers is printed, without any distinction between those that are supported by the server and those that are not. This is the same issue I noted in #332 for run_pfs().
In run_pfs(), the displayed output was corrected, but all ciphers were still being added to $pfs_ciphers, so the list of supported PFS ciphers sent to fileout() was incorrect.
This PR fixes both issues.
When certificate_info() is trying to determine what type of public key the server has so that it can determine whether the key size is acceptable, it sometimes looks at $cert_sig_algo rather than $cert_key_algo. This PR fixes that and also adds support for DSA public keys.
The dec2hex() was actually converting from hex to decimal. Since it was only being used in one place, and wasn't really needed there, I just deleted it.
