Config.CiphersSourceCipher selection
Cipher selection related utilities.
default is a list of ciphersuites this library uses by default.
supported is a list of ciphersuites this library supports (larger than default).
fs is a list of ciphersuites which provide forward secrecy (sublist of default).
http2 is a list of ciphersuites which are allowed to be used with HTTP2: not a member of bad cipher suites. These are only ephemeral key exchanges with AEAD ciphers.
fs_of ciphers selects all ciphersuites which provide forward secrecy from ciphers.
