True, but how is pkcs1pad_decrypt_complete() reachable from the encryption path of the code? Or, is there a hidden API assumption that the alg.decrypt callback will be called for every alg.encrypt call? It does not seem right. Same question for pkcs1pad_verify_complete(), which is the only other free path for this field. -- Dan Aloni
