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.
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 authors of Rijndael used to provide a homepage [2] for the algorithm. Care should be taken when implementing AES in software, in particular around side-channel attacks. The algorithm operates on plaintext blocks of 16 bytes. Encryption of shorter blocks is possible only by padding the source bytes, usually with null bytes. This can be ...
Bouncy Castle started when two colleagues were tired of having to re-invent a set of cryptography libraries each time they changed jobs working in server-side Java SE.One of the developers was active in Java ME (J2ME at that time) development as a hobby and a design consideration was to include the greatest range of Java VMs for the library, including those on J2ME.
Comparison of implementations of message authentication code (MAC) algorithms. A MAC is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed in transit (its integrity).
It offers support for many commonly used cryptographic algorithms, such as hash functions, message authentication codes, symmetric, asymmetric, stream and block encryption. Its development started in 1996 and as such IAIK-JCE was one of the first Java-based cryptography providers.

Example of a Key Derivation Function chain as used in the Signal Protocol.The output of one KDF function is the input to the next KDF function in the chain. In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a ...
