15 Pass a char *, pointing to a null-terminated string holding the list of
16 ciphers to use for the connection to the HTTPS proxy. The list must be
17 syntactically correct, it consists of one or more cipher strings sepa‐
18 rated by colons. Commas or spaces are also acceptable separators but
19 colons are normally used, !, - and + can be used as operators.
20
21 For OpenSSL and GnuTLS valid examples of cipher lists include
22 'RC4-SHA', ´SHA1+DES´, 'TLSv1' and 'DEFAULT'. The default list is nor‐
23 mally set when you compile OpenSSL.

29 For NSS, valid examples of cipher lists include 'rsa_rc4_128_md5',
30 ´rsa_aes_128_sha´, etc. With NSS you don't add/remove ciphers. If one
31 uses this option then all known ciphers are disabled and only those
32 passed in are enabled.
