RC4-MD5

Hello Openssl team,

We are currently facing an issue with RC4-MD5 cipher suite after upgrading
from openssl0.9.8q to openssl1.0.1j.

We see that on few platforms, RC4-MD5 cipher negotiation is returning bad
mac record error after receiving "Client Key Exchange" message.

Currently we are using proprietary md5 functions with following
configuration .

static const EVP_MD ios_md5_md=
{
    NID_md5,
    NID_md5WithRSAEncryption,
    MD5_LEN,
    0,
    md5init,
    md5update,
    md5final,
    NULL,
    NULL,
    EVP_PKEY_RSA_method,
    MD5_CBLOCK,
    sizeof(EVP_MD *)+sizeof(MD5_CTX),
};

 Is there any consideration for MD5 based on platform bits? Can anyone
share?

Thanks,
Rajeswari.
