Code example for DESedeKeySpec

    private String cipherAlgorithm = DEFAULT_ENCRYPTION_ALGORITHM;
    public final void setSecretKey(final String key) throws NoSuchAlgorithmException, InvalidKeyException,
            InvalidKeySpecException { 
        this.key = SecretKeyFactory.getInstance(this.cipherAlgorithm).generateSecret(new DESedeKeySpec(key.getBytes()));
    public final void setSecretKey(final Key key) {
        this.key = key;
     * Note: you MUST call this method before calling setSecretKey if you're not using the default algorithm.  You've been warned. 
     * @param cipherAlgorithm the cipher algorithm. 
    public final void setCipherAlgorithm(final String cipherAlgorithm) {
        this.cipherAlgorithm = cipherAlgorithm;
