Example 2 with NoSuchPaddingException

use of javax.crypto.NoSuchPaddingException in project OpenAM by OpenRock.

the class DataEncryptor method encryptWithAsymmetricKey.

/**
     * Encrypts the given data with an asymmetric key. The asymmetric 
     * encryption uses symmetric secret key for data encryption and sends
     * the secret key to the recipient by encrypting the same with given
     * transport key (publick key). 
     * @param data the data to be encrypted.
     * @param encryptionAlgorithm the encryption algorithm to be used.
     *        The encryption algorithm must be one of the supported
     *        algorithm by the underlying JCE encryption provider.
     *        Examples of encryption algorithms are "DES", "AES" etc. 
     * @param encryptionStrength the encryption strength for a given
     *                           encryption algorithm.
     * @param encKey the encryption key to be used. For PKI, this
     *               key should be public key of the intended recipient.  
     * @return the encrypted data in Base64 encoded format.
