NoSuchAlgorithmException: unrecognized algorithm name: PBEWithHmacSHA256AndAES_128

    Details

      Description

      javax.crypto.EncryptedPrivateKeyInfo does not recognize PBEWithHmacSHA256AndAES_128 and PBEWithHmacSHA256AndAES_256 although the documentation @
      https://docs.oracle.com/javase/8/docs/technotes/guides/security/StandardNames.html#AlgorithmParameters sees to indicate it should. This error is also observed with JDK 11.
