package com.springcryptoutils.core.cipher.symmetric;
import  org.springframework.beans.factory.InitializingBean;

The default implementation for generating symmetric encryption keys.

Author(s):
Mirko Caserta (mirko.caserta@gmail.com)
public class KeyGeneratorImpl implements KeyGenerator, InitializingBean {
	private String algorithm = "DESede";
	private String provider;

Sets the key algorithm. Default is DESede (triple DES).

Parameters:
algorithm the algorithm
	public void setAlgorithm(String algorithm) {
		this. = algorithm;
	}

Sets the provider name of the specific implementation requested (e.g., "BC" for BouncyCastle, "SunJCE" for the default Sun JCE provider).

Parameters:
provider the provider to set
	public void setProvider(String provider) {
		this. = provider;
	}

Generates a new symmetric encryption key.

Returns:
the new symmetric encryption key
	public byte[] generate() {
	}
		if (( == null) || (.length() == 0)) {
			 = javax.crypto.KeyGenerator.getInstance();
else {
			 = javax.crypto.KeyGenerator.getInstance();
		}
	}
