1.Obtaining the List of Supported Suites
$openssl ciphers -v ‘ALL:COMPLEMENTOFALL’
2.For example, you can ask it to list only cipher suites that are based on RC4
$openssl ciphers -v ‘RC4
备注：首先列出是优先的。
3.组合密钥
$openssl ciphers -v ‘RC4+SHA’
4.@STRENGT (按照算法等级顺序排列)
$openssl ciphers -v ‘DES-CBC-SHA DES-CBC3-SHA RC4-SHA AES256-SHA @STRENGTH’
5.测试算法速度
$openssl speed rc4 aes rsa ecdh sha
