in class PrivateKeyDecoder
input
- An input stream containing the encoded key.defaultCryptoSystem
- The crypto system to base the decoded key upon
(if no parameters were encoded with it).defaultKeyAlgorithm
- The type of key.
NoSuchAlgorithmException
- Thrown if the specified algorithm is
invalid.

InvalidCryptoSystemException
- Thrown if the specified crypto
system is invalid.
UnsupportedCryptoSystemException
- Thrown if the specified crypto
system is unsupported.
CryptoTokenException
- Thrown if an error occurs with the crypto
token or the crypto token is invalid.
CryptoUnsupportedOperationException
- Thrown if a call is made to
an unsupported operation.
IOException
- Thrown when an I/O error occurs.protected PrivateKey decodeKey(InputStream input, String algorithm) throws NoSuchAlgorithmException, InvalidKeyEncodingException, InvalidKeyException, InvalidCryptoSystemException, UnsupportedCryptoSystemException, CryptoTokenException, CryptoUnsupportedOperationException, IOException
input
- The input stream containing the encoded key data.algorithm
- A String representing the name of the algorithm used to
encode the key.
NoSuchAlgorithmException
- Thrown if the specified algorithm is invalid.
InvalidKeyEncodingException
- Thrown if the key is improperly
formatted or encoded.
InvalidKeyException
- Thrown if the key is invalid.
InvalidCryptoSystemException
- Thrown if the crypto system is
invalid.
