                                                  String encodedKeyAlgorithm)
                                           throws InvalidKeyException,
                                                  NoSuchAlgorithmException

Construct a public key from its encoding.

参数:

encodedKey - the encoding of a public key.

encodedKeyAlgorithm - the algorithm the encodedKey is for.

返回:

a public key constructed from the encodedKey.

抛出:

InvalidKeyException

NoSuchAlgorithmException

constructPrivateKey

private static final PrivateKey constructPrivateKey(byte[] encodedKey,
                                                    String encodedKeyAlgorithm)
