git_sshripped_filter

Git clean/smudge/diff filter operations for git-sshripped.

Overview

This crate bridges the encryption layer to Git's filter mechanism. It implements the three filter operations that run transparently during normal Git workflows:

• clean -- encrypts plaintext when staging (git add). Errors if the repository is locked and the file is unencrypted.
• smudge -- decrypts ciphertext when checking out. Passes ciphertext through unchanged when the repository is locked.
• diff -- decrypts ciphertext for textconv display. Errors if the repository is locked.

Each function accepts an optional repo_key; a None key indicates the repository is locked.

Key Functions

• clean(algorithm, repo_key, path, content) -- encrypt for staging.
• smudge(repo_key, path, content) -- decrypt for checkout.
• diff(repo_key, path, content) -- decrypt for diff display.

Usage

Part of the git-sshripped workspace. This crate is not intended for standalone use.
