#ed25519

HD Wallet WASM - Comprehensive BIP-32/39/44 hierarchical deterministic wallet implementation in C++ compiled to WebAssembly

Open .skill Protocol - a sealed, inspectable package format for AI agent skills. Reference implementation: skillerr.

Small, wasm-friendly, zero-dependencies Ed25519 and X25519 implementation for Rust.

RSS for state. Open portable evidence layer for machine state - preserving what an agent or system saw, produced, derived and learned, so another party or future agent can verify the lineage independently.

Causalontology - the world's first programming-language-neutral standard and shared commons for reified causation. AGI's Missing Link.

AI agent Skill, MCP server, and CLI for transacting in the Nano (XNO) cryptocurrency. Manage wallets securely via OWS, sign messages, and build seamless zero-fee integrations.

The verifiable trail of agent actions — signed, tamper-evident execution receipts for AI agents (MCP & A2A).

Ed25519 high-performance public-key signature system as a RubyGem (MRI C extension and JRuby Java extension)

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).

Ruby FFI binding to the Networking and Cryptography (NaCl) library (a.k.a. libsodium)

Agent Governance Protocol — Experimental governance layer for multi-agent systems.

BIP32 for Secp256k1/Ed25519

A pure Rust implementation of the Minisign signature tool.

Batteries-included Go cryptography library: AES-256-GCM & ChaCha20-Poly1305 authenticated encryption, argon2id/bcrypt password hashing, HMAC & Ed25519 signing, HKDF, key rotation, KMS envelope encryption, and secure random — safe defaults, stdlib-only, byte-for-byte interop with the TypeScript crypt-ts.

This simple tool can be used to generate an RSA PKCS#8 or Ed25519 key pairs.

Cryptographic trust infrastructure for MCP servers — signed manifests, TOFU pinning, two-gate enforcement, and the "npm audit" scanner.

A small Rust crate to verify Minisign signatures.

Automated cacert.pem management for PHP projects

Guardrails for AI agents, with a receipt. Blocks destructive tool calls before they run and signs every decision into a hash-chained record anyone can verify with an open-source tool.

Ed25519 signature verification for Solana programs

When sending costs fractions of a cent, recipients drown. HAP (Human Attestation Protocol) is an open standard that lets senders prove they made real, non-fakeable effort to reach you so recipients can prioritize signal over noise.

🛡️ A modern Go library for CMS/PKCS#7 messages with Ed25519 support.
