31 Pass a char *, pointing to a zero terminated string holding the list of
32 ciphers to use for the connection to the HTTPS proxy. The list must be
33 syntactically correct, it consists of one or more cipher strings separated by
34 colons. Commas or spaces are also acceptable separators but colons are
35 normally used, \&!, \&- and \&+ can be used as operators.
37 For OpenSSL and GnuTLS valid examples of cipher lists include 'RC4-SHA',
38 \'SHA1+DES\', 'TLSv1' and 'DEFAULT'. The default list is normally set when you

45 For NSS, valid examples of cipher lists include 'rsa_rc4_128_md5',
46 \'rsa_aes_128_sha\', etc. With NSS you don't add/remove ciphers. If one uses
