Why RSA considers Hash algorithm

Hello, I was looking libcrypto code, and found that DSA_sign and ECDSA_sign ignore hash algorithm while RSA_sign do not. Are there any reason for this? -- Lucas Gonçalves Martins

BN_copy on 64 bits Environment

Hello, I'm working on a software that uses libcrypto and the OpenSSL engine interface for a HSM. We developed an OpenSSL engine that was working fine until we try it on a 64 bit operational system. For some reason, the function BN_copy isn't working in a 64 bits environment. The code is running
