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.

WebbA cryptogram is a short piece of encrypted text using any of the classic ciphers. Usually it is simple enough that it can be solved by hand. The most common types of cryptograms are monoalphabetic substitution ciphers, called Aristocrats if they contains spaces or Patristocrats if they don't. Another common name is cryptoquip.
