codegroup

Convert any file, including binary, into 5 letter code

Codegroup converts any file, of any format including raw binary, into a set of five letter uppercase codegroups. The codegroup format includes a 16 bit CRC and file length to verify message integrity. Codegroup does NO CRYPTO. It's purely a file format converter much like base64 or uuencoding. Unlike other traditional file encoding algorithms such as base64 or uuencoding, codegroup exclusively uses the 26 letter alphabet. Codegroup is ideal for transferring short binary files over a voice or morse code channel.
