cryptio is a modern Go library for secure password-based encryption and decryption, featuring Argon2id key derivation and AES-GCM. Choose your desired security level—Standard, Medium, or High—for optimal protection and performance balance.
A proof of concept for how you can turn a duplex-style AEAD scheme (e.g., AEGIS) into a memory-hard password-based KDF.
Encryption adapter for https://github.com/vladimiry/fs-json-store
A password manager that utilizes PostgreSQL, AES Encryption, and PBKDF2 to create a simple and secure password storage and retrieval system.
expo-crypto-lib is a universal toolkit for hybrid RSA + AES encryption and BIP-39 mnemonic key derivation. Built for Expo and React Native, with native-standard security and seamless Node.js compatibility. JavaScript-only module; it has no native iOS/Android code and does not require prebuild hooks.
