Constructor Details

DefaultCryptoHandler

public DefaultCryptoHandler(String pKeyXML,
 int pKeyLength,
 String pKeyID,
 String pChainingMode,
 String pPadding)
                     throws FSHelperException

Creates the object of CryptoHandler. This is the default implementation for the Crypto Handler. This implementation supports RSA based Encryption, with PKCS1Padding, as a ECB chaining Mode

Parameters:

pKeyXML - Private key in xml. The components should be in hexadecimal format.

pKeyLength - Length of the private Key. Example - 256

pKeyID - A unique Id which is mapped to the public key part on Policy Server.

pChainingMode - Chaining mode to be used for encrypt or decrypt. Example - ECB

pPadding - Padding to be used for encrypt or decrypt. Example - PKCS1Padding

Throws:

FSHelperException - if values is not valid.
