If you want to know which ciphers are available within your
openssl binary just run
openssl ciphers -V 'ALL:eNULL'. This shows you all ciphers available and the details, e.g.
0xC0,0x30 - ECDHE-RSA-AES256-GCM-SHA384 TLSv1.2 Kx=ECDH Au=RSA Enc=AESGCM(256) Mac=AEAD 0xC0,0x2C - ECDHE-ECDSA-AES256-GCM-SHA384 TLSv1.2 Kx=ECDH Au=ECDSA Enc=AESGCM(256) Mac=AEAD 0xC0,0x28 - ECDHE-RSA-AES256-SHA384 TLSv1.2 Kx=ECDH Au=RSA Enc=AES(256) Mac=SHA384 0xC0,0x24 - ECDHE-ECDSA-AES256-SHA384 TLSv1.2 Kx=ECDH Au=ECDSA Enc=AES(256) Mac=SHA384 ....
If you instead want to know which ciphers are available when using a specific cipher string inside the server use this cipher string instead of
ALL:eNULL. Note that you need to make sure that your server and the
openssl binary actually use the same OpenSSL library - and the exact same library build (i.e. same *.so file) and not another library with the same OpenSSL version number.
