2017-01-24tls: add 2nd cipher_id, TLS_RSA_WITH_AES_128_CBC_SHA, so far it doesn't workDenys Vlasenko
Good news that TLS_RSA_WITH_AES_256_CBC_SHA256 still works with new code ;) This change adds inevitable extension to have different sized hashes and AES key sizes. In libbb, md5_end() and shaX_end() are extended to return result size instead of void - this helps *a lot* in tls (the cost is ~5 bytes per _end() function).

A new applet, ssl_client, is the TLS debug thing now. It doubles as wget's NOMMU helper. In MMU mode, wget still forks, but then directly calls TLS code, without execing. This can also be applied to sendmail/popmail (SMTPS / SMTP+starttls support) and nc --ssl (ncat, nmap's nc clone, has such option). function old new delta tls_handshake - 1691 +1691 tls_run_copy_loop - 443 +443 ssl_client_main - 128 +128 packed_usage 30978 31007 +29 wget_main 2508 2535 +27 applet_names 2553 2560 +7 ... xwrite_encrypted 360 342 -18 tls_main 2127 - -2127 ------------------------------------------------------------------------------ (add/remove: 4/1 grow/shrink: 13/8 up/down: 2351/-2195) Total: 156 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
