About:
Transcrypt is a script that enables transparent encryption for files within a Git repository. It leverages Git's clean/smudge filters to automatically encrypt files upon commit and decrypt them upon checkout. This allows developers to securely store sensitive data like credentials and configuration files alongside their code without exposing secrets in the repository history.

Key Features:

Automatic encryption/decryption via Git filters
Supports multiple encryption backends (OpenSSL, GnuPG)
Per-repository configuration via .gitattributes
Simple command-line interface for setup and usage

Use Cases:

Storing API keys and credentials in private Git repos
Managing encrypted configuration files for different environments
Collaborating on projects requiring sensitive data without exposing secrets

Alternatives:

git-crypt – Similar functionality but requires GPG keys for all collaborators
blackbox – More complex setup, better suited for large teams with strict key management
