Encoding Algorithm

The main purpose of these functions are to allow encoding a string from base 256 to a special base 255. The function view the strings as numbers and simply change what base they are written in. This is not recommended for very long strings; otherwise, the encoding and decoding process can take a... Platforms: Windows, Mac, *nix, Python, BSD Solaris

basE91 is an advanced method for encoding binary data as ASCII characters. It is similar to UUencode or base64, but is more efficient. The overhead produced by basE91 depends on the input data. It amounts at most to 23% (versus 33% for base64) and can range down to 14%, which typically occurs on... Platforms: Windows, Mac, *nix, C/C++, BSD Solaris

LZ77 is a compression algorithm upon which most popular compression formats are based; PKZIP, GZIP, LHA, RAR, etc. This script allows you to compress blocks having the size of maximum 256 bytes. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script takes a decimal number, converts it into binary, takes the first six numbers in that, converts that into a decimal number, and from there makes it a letter("m") according to the base64 code. Platforms: Windows, Mac, *nix, Python, BSD Solaris

UUDeview is a program that helps you transmit and receive binary files over the Internet, using electronic mail or newsgroups. The UUDeview package includes both an encoder and a decoder. The decoder automatically detects the type of encoding used, offering MIME's Base64 and BinHex as well as the... Platforms: Windows, Mac, *nix, C/C++, BSD Solaris
