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

46 For NSS, valid examples of cipher lists include 'rsa_rc4_128_md5',
47 \'rsa_aes_128_sha\', etc. With NSS you don't add/remove ciphers. If one uses
48 this option then all known ciphers are disabled and only those passed in are
