go-scratch
Scratch utilities and how to items, examples, in Go
bin-r-w
Very simple example of read & write of packed binary data. I implemented something like this when replacing a Python process that generated large binary files to feed some storm simulation routines. Look at the test file for implementation.
enc
An AES file encryption routine in Go designed to encrypt in chunks so it can handle large files without exceeding memory and to be compatible with existing Python and C implementation of the Encrypt/Decrypt routines as coded in enc.py
