WebFeb 2, 2024 · A cipher is a method for encrypting a message, intending to make it less readable. As for the Caesar cipher, it's a substitution cipher that transforms a message by shifting its letters by a given offset. Let's say we want to shift the alphabet by 3, then letter A would be transformed to letter D, B to E, C to F, and so on. WebThe Java Cryptography Architecture (JCA) is a set of APIs to implement concepts of modern cryptography such as digital signatures, message digests, and certificates. This specification helps developers integrate security in their applications. Audience This tutorial has been prepared for beginners to make them understand the basics of JCA.
