In computing, the Java Cryptography Architecture (JCA) is a framework for working with cryptography using the Java programming language. It forms part of the Java security API, and was first introduced in JDK 1.1 in the java.security package. The JCA uses a "provider"-based architecture and contains a set of APIs for various purposes, such as ...
IAIK-JCE is a Java-based Cryptographic Service Provider, which is being developed at the Institute for Applied Information Processing and Communications (IAIK) at the Graz University of Technology. It offers support for many commonly used cryptographic algorithms, such as hash functions , message authentication codes , symmetric , asymmetric ...
The Java Cryptography Extension (JCE) is an officially released Standard Extension to the Java Platform and part of Java Cryptography Architecture (JCA). JCE provides a framework and implementation for encryption , key generation and key agreement , and Message Authentication Code (MAC) algorithms.

Crypto-J is a Java encryption library. In 1997, RSA Data Security licensed Baltimore Technologies' J/CRYPTO library, with plans to integrate it as part of its new JSAFE encryption toolkit [10] and released the first version of JSAFE the same year. [11] JSAFE 1.0 was featured in the January 1998 edition of Byte magazine. [12]
Other logical operations such and AND or OR do not have such a mapping (for example, AND would produce three 0's and one 1, so knowing that a given ciphertext bit is a 0 implies that there is a 2/3 chance that the original plaintext bit was a 0, as opposed to the ideal 1/2 chance in the case of XOR) [a]
The four-square cipher is a manual symmetric encryption technique. [1] It was invented by the French cryptographer Felix Delastelle.. The technique encrypts pairs of letters (digraphs), and falls into a category of ciphers known as polygraphic substitution ciphers.
In particular, the length of the output should be the same as the length of the input (the picture on the right has S-boxes with 4 input and 4 output bits), which is different from S-boxes in general that could also change the length, as in Data Encryption Standard (DES), for example.
