ed25519

End-to-end integration harness and demonstration suite for the EVALinux Crypto Suite (CBOR FIDO, ECC Constant, PQC Constant, DBus Native, and TPM2 TSS).

Constant-time Ed25519 digital signatures and X25519 ECDH key agreement for Crystal backed by libsodium guarded memory and page protection.

ATC/1.0 - Agent Trust Card protocol (Ed25519, RFC 8785 JCS, 10 controles) + x402 paywall kit. Espejo de alicelabs-llc/universal-trust-adapter (backup)

Verifiable agent continuity protocol: Ed25519-signed memory, hash-linked DAG, key rotation. Local-first, zero-LLM. Published on npm (alethech-cli) and PyPI (alethech).

CLI tools for working with .aleth encrypted memory files — inspect, verify, and search agent memory without decrypting the whole chain. Published on npm as alethech-tools.

Comprehensive cryptographic library for Kit using libsodium

A persistent-memory AI agent with cryptographically signed, hash-chained, tamper-evident memory. Pre-commit quality scoring quarantines prompt-injection; protected zones guard core records. Scans its own history for recurring gaps and proposes improvements for human review. Provider-agnostic (Claude, GPT, Gemini, DeepSeek, OpenRouter, Ollama).

A simple and efficient authentication server written in Rust, providing JWT-based authentication via REST API.

This project contains shell scripts I use to create keys and certificates in order to explore and evaluate using cosign to attach certificates and certificate chains to OCI images.

Map ssh-ed25519 keys into x25519 keys

Pure Python port of minisign: a dead simple tool to sign files and verify digital signatures.
