Implements digital signatures using the Ed25519 algorithm (Curve25519), covering key-pair generation, signing, signature verification, and security tradeoffs versus RSA and ECDSA. Use when adding message or artifact signing and authentication-integrity checks to a system, or when advising on Ed25519 key properties and validation criteria.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'implementing-digital-signatures-with-ed25519' ] || [ -L ~/.agents/skills/'implementing-digital-signatures-with-ed25519' ]; then echo 'A skill folder named implementing-digital-signatures-with-ed25519 already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/mukul975/Anthropic-Cybersecurity-Skills' "$d" && git -C "$d" checkout --quiet '54a798831d2266a3ca61ce68a7acb80b81160d57' -- 'skills/implementing-digital-signatures-with-ed25519' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/implementing-digital-signatures-with-ed25519' ~/.agents/skills/'implementing-digital-signatures-with-ed25519' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'implementing-digital-signatures-with-ed25519' ~/.claude/skills/'implementing-digital-signatures-with-ed25519' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
