[PATCH] asymmetric keys: explicitly add the leading zero byte to encoded message

2013-07-31 Thread Lee, Chun-Yi
From: Chun-Yi Lee Per PKCS1 spec, the EMSA-PKCS1-v1_5 encoded message is leading by 0x00 0x01 in its first 2 bytes. The leading zero byte is suppressed by MPI so we pass a pointer to the _preceding_ byte to RSA_verify() in original code, but it has risk for the byte is not zero because it's not
