Package tribble.crypto Description

Cryptographic Classes

These classes provide cryptographic services, such as block encryption and decryption, hashing algorithms, and digital signature algorithms, etc.

Cipher implementation objects are created by class Cipher.

Cipher objects (of type javax.crypto.Cipher) are constructed from a combination of a cipher SPI object, which is one of generic cipher algorithm types derived from class CipherSpi, and a primitive cipher algorithm, which is a class derived from class AbstractCipher.

Cipher SPI implementations derived from class CipherSpi are further divided into two types, BlockCipherSpi and StreamCipherSpi. These two base classes implement the encryption cipher service provider interfaces (SPIs) that serve as the foundation upon which the rest of this cryptographic package is built.

Cipher algorithm implementations derived from AbstractCipher are further divided into two types, SymmetricCipher and AsymmetricCipher. These two base classes implement the primitive encryption cipher algorithms that serve as the foundation upon which the rest of this cryptographic package is built. These two classes, in other words, are the fundamental encryption algorithms for this entire package.
