secure-files-go-gui

This is a GUI for secure-files-go - a file encryption/decryption program written in Go. The original version of the program was written in Zig.

This implements RFC8439 which uses ChaCha20 as the cipher and Poly1305 for authentication, and Argon2 for key derivation (KDF) from a given password.

This is in no shape or form a well-polished program, so use at your own risk.
