encrypt

public static String encrypt(String key,
             String source)

Uses the key to encrypt the source string into a base-64 encoded string using a DES/ECB/PKCS5Padding cipher.

Parameters:

key - The key to use for encryption. Must be at least 8 characters in length.

source - The plain-text to encrypt.

Returns:

A Base-64 encoded encypted string. Its safe to assume that the encrypted string will be at least twice the size of the plain-text.
