It depends on how you control OpenSSL to process the verification. Read the man 
page of SSL_CTX_set_verify (and related) function. Seems you can find the doc 
there: https://wiki.openssl.org/index.php/Manual:SSL_CTX_set_verify(3)

Either by using an API as ‘SSL_get_ciphers’ or a command line tool ‘openssl 
ciphers some-options', read related documentation for details.
