Package org.apache.shiro.crypto Description

Cryptography Cipher and Hashing components that greatly simplify the JDK's cryptography concepts and add additional convenient behavior.

The most important interface in this package is the CipherService interface, which allows one to encrypt and decrypt sensitive data.
