/**
 * Configuration class that registers a {@link BeanFactoryPostProcessor} that wraps all {@link PropertySource} defined in the {@link Environment}
 * with {@link EncryptablePropertySourceWrapper} and defines a default {@link StringEncryptor} for decrypting properties
 * that can be configured through the same properties it wraps.
 * The {@link StringEncryptor} bean is only defined when no other
 * bean of type {@link StringEncryptor} is present in the Application Context, thus allowing for custom definition if required.
 * The default {@link StringEncryptor} can be configured through the following properties: 
 *
