Re: generating sha256 hashes with openssl?

std::string should strcpy though, no?

From a cursory glance at the function (and without knowing what
exactly failed), it potentially looks like you have a dangling
pointer.

You assign to your password class member an array of characters which
you created on the heap (and then delete).

Hello all,
I've been trying to figure this out based on documentation from openssl
(what little there is) and some info from google, but it still seems to be failing: Any ideas would be great on where I might be going wrong; here is 
the function
void Player::SetPassword(const std::string &s)
{
SHA256_CTX context;
unsigned char *hash = new unsigned char[SHA256_DIGEST_LENGTH+1];
memset(hash, 0, SHA256_DIGEST_LENGTH+1);

SHA256_Init(&context);
SHA256_Update(&context, (unsigned char*)s.c_str(), s.length());
SHA256_Final(hash, &context);
    _password=(char*)hash;
delete []hash;
}
Thanks,
Ty
