A small Go command-line tool to encrypt and decrypt files with AES-128 or AES-256 in GCM mode
Sometimes you just need to encrypt a file. Not set up a key management system, not learn the gpg command line again, not pull a heavy dependency — just turn secrets.txt into secrets.bin with a key you control. That’s the niche gocrypt fills for me.
