Understanding Encryption and Security through Java Cryptography Architecture
For a long time, Java has provided security-related functions. Among the security-related functions, Java Cryptography Architecture (JCA) is the core one. JCA uses a provider structure with a variety of APIs related to security. These functions are essential for modern IT communication encryption technology, including Digital Signature, Message Digest (hashs), Certificate, Certificate Validation, creation and management of Key, and creation of Secure Random Number.
