From 8a130a2aa069620db40dffcaf6be4bd1c6315aa4 Mon Sep 17 00:00:00 2001 From: Green Hacker Date: Sat, 11 Oct 2025 11:21:04 +0530 Subject: [PATCH] feat(core): implement offline secrets manager with AES-256 encryption Implements a comprehensive offline secrets manager for securely storing and managing environment variables across multiple projects. Features: - AES-256 encryption using Fernet symmetric encryption - PBKDF2 key derivation with 480,000 iterations (OWASP recommended) - SQLite database with SQLAlchemy ORM - Master password protection with SHA-256 hashing - Audit logging for all operations - Rich CLI interface with beautiful terminal output - Comprehensive test suite with 40+ test cases Core Modules: - src/crypto/encryption.py: Encryption/decryption logic - src/core/models.py: Database models (Config, Project, EnvVar, AuditLog) - src/core/database.py: Database connection management - src/core/storage.py: Main storage interface and business logic - src/cli/main.py: Complete CLI implementation with 10 commands CLI Commands: - init: Initialize storage with master password - create-project: Create new projects - add: Add/update environment variables - list: List projects or variables - get: Retrieve specific variable - search: Search across all projects - export: Export to .env file - delete: Delete variables - delete-project: Delete entire projects Security Features: - Offline-first design (no cloud dependencies) - Encryption at rest for all secrets - Secure password input with masking - Audit trail for security review - Cascade deletion for data integrity Testing: - test_encryption.py: 20+ encryption tests - test_storage.py: 20+ storage and integration tests - Coverage for edge cases, unicode, special characters Closes #hacktoberfest Addresses the need for secure, centralized environment variable management --- IMPLEMENTATION.md | 193 +++++++++++++++++ main.py | 6 + src/cli/main.py | 245 ++++++++++++++++++++-- src/core/database.py | 72 +++++++ src/core/models.py | 83 ++++++++ src/core/storage.py | 443 +++++++++++++++++++++++++++++++++++++++ src/crypto/encryption.py | 123 +++++++++++ tests/test_encryption.py | 136 ++++++++++++ tests/test_storage.py | 322 ++++++++++++++++++++++++++++ 9 files changed, 1608 insertions(+), 15 deletions(-) create mode 100644 IMPLEMENTATION.md create mode 100644 main.py create mode 100644 src/core/database.py create mode 100644 src/core/models.py create mode 100644 src/core/storage.py create mode 100644 src/crypto/encryption.py create mode 100644 tests/test_encryption.py create mode 100644 tests/test_storage.py diff --git a/IMPLEMENTATION.md b/IMPLEMENTATION.md new file mode 100644 index 0000000..6513643 --- /dev/null +++ b/IMPLEMENTATION.md @@ -0,0 +1,193 @@ +# Offline Secrets Manager Implementation + +## Overview + +This implementation adds a fully functional offline secrets manager to ENV Storage Manager.
