Missing error status when retries are exhausted

[headscott]

Affected Code:

src/pk/ecc/ecc_sign_hash_internal.c:102

   if (max_iterations == 0) {
      goto errnokey;
   }

When all LTC_PK_MAX_RETRIES attempts are exhausted without producing a valid signature, the code jumps to errnokey without setting err. This can cause the function to incorrectly return CRYPT_OK.

Suggested fix:

   if (max_iterations == 0) {
      err = CRYPT_ERROR;
      goto errnokey;
   }
