/**
* Configuration class that registers a {@link BeanFactoryPostProcessor} that wraps all {@link PropertySource} defined in the {@link Environment}
* with {@link com.ulisesbocchio.jasyptspringboot.wrapper.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:
*
*
* Key Required Default Value
*
*
* jasypt.encryptor.password True -
*
*
* jasypt.encryptor.algorithm False PBEWithMD5AndDES
*
*
* jasypt.encryptor.keyObtentionIterations False 1000
*
*
* jasypt.encryptor.poolSize False 1
*
* jasypt.encryptor.providerName False SunJCE
*
*
* jasypt.encryptor.saltGeneratorClassname False org.jasypt.salt.RandomSaltGenerator
*
*
* jasypt.encryptor.stringOutputType False base64
*
