/**
*
* Utility class for easily performing normal-strength encryption of texts.
*
*
* This class internally holds a {@link StandardPBEStringEncryptor}
* configured this way:
*
* - Algorithm: PBEWithMD5AndDES.
* - Key obtention iterations: 1000.
*
*
*
* The required steps to use it are:
*
* - Create an instance (using new).
* - Set a password (using {@link #setPassword(String)} or
* {@link #setPasswordCharArray(char[])}).
* - Perform the desired {@link #encrypt(String)} or
* {@link #decrypt(String)} operations.
*
*
*
* This class is thread-safe.
