MagicCrypt is a Java/PHP/NodeJS/Rust library to encrypt/decrypt strings, files, or data, using Data Encryption Standard(DES) or Advanced Encryption Standard(AES) algorithms. It supports CBC block cipher mode, PKCS7 padding and 64, 128, 192 or 256-bits key length.

An implementation of the Frost Distributed Key Generation

Verifiable Secret Sharing Schemes

A utility library for SHA-256 hashing and verification.

PHP Privacy - The OpenPGP library in PHP language

Canonical DIG peer mTLS: the shipped public DigNetwork CA, per-peer node certs, rustls mutual-auth configs, peer_id = SHA256(SPKI DER), and the #1204 BLS-G1 cert binding.

A performant, 100% native-julia SHA1, SHA2, and SHA3 implementation

Majik Key is a next-generation seed phrase account library for creating and managing mnemonic-based identities. It provides a post-quantum ready, high-security bridge between BIP39 mnemonics and the Majikah ecosystem.

Majik Signature is a hybrid post-quantum content signing and verification library for the Majikah ecosystem. Built on top of Majik Key, it provides tamper-proof, forgery-resistant digital signatures for any content format — using a dual-algorithm architecture that combines classical Ed25519 with post-quantum ML-DSA-87 (FIPS-204).

This crate is a repository of MLS / RFC9420-related data structures.
