Webb28 nov. 2024 · The XOR encryption algorithm can be applied to any digital/binary information, included text based information encoded using the 8-bit ASCII code. In this case the encryption key can be expressed as a string of characters. By itself, the XOR encryption can be very robust if: It is based on a long key that will not repeat itself. WebbOverview. Java Cryptographic Extensions (JCE) is a set of Java API’s which provides cryptographic services such as encryption, secret Key Generation, Message Authentication code and Key Agreement. The ciphers supported by JCE include symmetric, asymmetric, block and stream ciphers. JCE was an optional package to JDK v 1.2.x and 1.3.x.
