Method: OpenSSL::SSL::SSLContext#ciphers=

Defined in:
ossl_ssl.c

#ciphers=(v) ⇒ Object

ctx.ciphers = [name, …]

ctx.ciphers = [[name, version, bits, alg_bits], ...]

Sets the list of available ciphers for this context. Note in a server context some ciphers require the appropriate certificates. For example, an RSA cipher can only be chosen when an RSA certificate is available.
