Hi, I asked this question yesterday on the openssl-users list, but I haven't
got any reply yet... Is this openssl-dev list a proper place for my
question? Hope I can get a hint from here, thanks.

Hi folks,
When a client receives a server hello, how can I find out the ciphersuite
name according to the ciphersuite number?
From server hello's header (SSL version 3.0), I can read out the cipher
suite number, which is, for example 0x0004, and my Ethereal (Version
0.10.13) shows it is TLS_RSA_WITH_RC4_128_MD5 (0x0004). In
..../openssl/ssl/s3_lib.c, I found out that /* Cipher 04 */ is
SSL3_TXT_RSA_RC4_128_MD5. Is this a correct map? If it is, which API I can
use to get this name?
I tried ssl3_get_cipher(unsigned int u), it returns a different name. For
0x0004, it returns /* Cipher 36 */ TLS1_TXT_DH_DSS_WITH_AES_256_SHA (
"DH-DSS-AES256-SHA"). The function is like this:
SSL_CIPHER *ssl3_get_cipher(unsigned int u)
{
if (u < SSL3_NUM_CIPHERS)
return(&(ssl3_ciphers[SSL3_NUM_CIPHERS-1-u]));
else
return(NULL);
}
Which is a correct map? Ethereal's Cipher 04 or ssl3_get_cipher()'s Cipher
36?
Thanks,
Rick
