Hi! I am doing a SHA256 on a RSA* private key. I used the result as a symmetric key for AES encryption.
/////////////////////////////////////////////////////////////////////////////////////////// int length = RSA_size(rsaPrivateKey); SHA256_CTX sha256ctx; SHA256_Init(&sha256ctx); SHA256_Update(&sha256ctx, rsaPrivateKey, length); unsigned char* hash = new unsigned char[SHA256_DIGEST_LENGTH]; SHA256_Final(hash, &sha256ctx); /////////////////////////////////////////////////////////////////////////////////////////// If I execute this code couples of time in the same process execution, hash variable is always the same value (this is normal!!). But, each time I restart the application, hash value is different. In the past I used the same pattern, with SHA512 instead of SHA256, and with a char* instead of a RSA* and I dit not have this problem. Any idea what's going on ? -- View this message in context: http://www.nabble.com/Question-about-SHA256-on-a-RSA*-key-tp21093222p21093222.html Sent from the OpenSSL - User mailing list archive at Nabble.com. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
