How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
This project is a Python cryptography library that provides a collection of cryptographic primitives and high-level recipes for implementing secure encryption and authentication. It functions as a symmetric encryption toolkit and a cryptographic hash provider, offering both a low-level cryptographic interface for building custom protocols and high-level tools for securing data. The library covers a broad range of security capabilities, including symmetric data encryption, the derivation of cryptographic keys from passwords or secret values, and data integrity verification through the generati
php-encryption is a symmetric encryption library for PHP that provides tools for authenticated encryption and key derivation to ensure data confidentiality and integrity. It functions as a cryptography toolkit that wraps complex primitives into simplified interfaces to prevent common implementation errors. The library includes a binary-safe ciphertext serializer to maintain data structure during storage and transmission, as well as a password-based key derivation tool that transforms low-entropy passwords into cryptographically strong keys through iterative processes. The project covers a br
andOTP is an open-source multi-factor authentication client for Android. It functions as a time-based and HMAC-based one-time password authenticator for managing two-factor authentication tokens. The application serves as an encrypted vault for authentication secrets, utilizing hardware keystores, passwords, or PINs to secure the account database. It is specifically designed to support automated backups by exporting account databases via system broadcasts for integration with external automation tools. The software covers the management of authentication tokens through QR code scanning and t
git-crypt is a transparent cryptography layer and secret manager for Git repositories. It encrypts specific files so they remain as ciphertext on remote servers while appearing as plaintext in local directories. The tool uses Git attributes to define the scope of files and directories targeted for encryption. It supports both symmetric secret key encryption for shared access and asymmetric public key encryption to control decryption permissions among multiple collaborators. The system automates the encryption and decryption process through hook-based filters that trigger during commit and ch
This is a blind image watermarking and steganography tool designed to embed and extract hidden data from images without requiring the original source file. It functions as a framework for concealing text or bit arrays within images using mathematical transforms to ensure the marks remain invisible to the viewer.
