Cryptography

Cryptosystems often compress data before encryption for added security; compression
prior to encryption helps remove redundancies and patterns that might facilitate
cryptanalysis. However, many ordinary lossless compression algorithms introduce
predictable patterns (such as headers, wrappers, and tables) into the compressed data that
may actually make cryptanalysis easier. Therefore, cryptosystems often incorporate
specialized compression algorithms specific to the cryptosystem—or at least
demonstrated or widely held to be cryptographically secure—rather than standard
compression algorithms that are efficient but provide potential opportunities for
cryptanalysis.

Executables

Self-extracting executables contain a compressed application and a decompressor. When
executed, the decompressor transparently decompresses and runs the original application.
This is especially often used in demo coding, where competitions are held for demos with
strict size limits, as small as 1k. This type of compression is not strictly limited to binary
executables, but can also be applied to scripts, such as JavaScript.
