Java Cryptography Architecture (JCA) is a framework that provides a set of APIs and algorithms for implementing cryptographic operations in Java applications. It enables developers to create secure applications by supporting various cryptographic functions, including encryption, decryption, key generation, and digital signatures. The JCA works seamlessly with the Java Cryptography Extension (JCE), which adds additional features such as support for elliptic curve cryptography, making it particularly relevant in contexts where advanced encryption schemes like ECIES are employed.
