WebCryptography is the study and implementation of processes, which manipulate data for the purpose of hiding and authenticating information. The IBM icryptographic services help ensure data privacy, maintain data integrity, authenticate communicating parties, and prevent repudiation when a party refutes having sent a message. Cryptographic algorithms
Cryptographic hash functions are cryptographic algorithms that generate and use keys to encrypt data, and such functions may be viewed as keys themselves. They take a message of any length as input, and output a short, fixed-length hash , which can be used in (for example) a digital signature.
