Example 97 with SecretKeyFactory

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

the class DataEncryptor method encryptWithSymmetricKey.

/**

     * using given shared secret. 
     * @param data the data to be encrypted.

     *        The encryption algorithm must be one of the supported
     *        algorithm by the underlying JCE encryption provider.
     *        For password based encryptions, the encryption algorithm
     *        PBEWithMD5AndDES is commonly used. 
     * @param secret the shared secret to be used for symmetric encryption.
