encryption

Audit and harden encryption across the full stack. Checks data-at-rest encryption (database TDE, field-level AES-256-GCM, file storage SSE, backup encryption), data-in-transit security (TLS 1.2+, HSTS, certificate pinning, mTLS, WebSocket WSS), key management (KMS, envelope encryption, key rotation, key separation), password hashing (argon2id, bcrypt, scrypt, PBKDF2 work factors, salt uniqueness, migration plans), token security (JWT signing algorithms, CSPRNG, refresh token rotation), and API key management (hashed storage, scoping, revocation). Use when you need to audit crypto, fix weak hashing, implement envelope encryption, rotate keys, upgrade TLS, or harden token generation. It's a reusable SKILL.md instruction set that loads into your AI coding assistant on demand, no prompt engineering, no copy-pasting every session.

Run `npx @skills-hub-ai/cli install encryption` from your terminal. The CLI writes the SKILL.md to the correct location for your AI tool (e.g. ~/.claude/skills/encryption/ for Claude Code or ~/.cursor/skills/ for Cursor with --target cursor) and adds it to your project's .skills.json lockfile.

encryption runs in Claude Code. It follows the open Agent Skills standard (SKILL.md), so the same skill works in every supported tool without modification.

Yes. Every skill on skills-hub.ai is free and open-source. There are no premium tiers, paywalls, or usage limits. You only pay for whatever AI assistant you're already using.

In Claude Code, type `/encryption` (or whatever slash command the skill registers) and the AI follows the skill's instructions immediately. You can also reference it by name in natural language, your AI loads the skill into context when relevant.

Yes. Commit your project's .skills.json lockfile and teammates run `npx @skills-hub-ai/cli install` (no args) to install every skill at the exact version you pinned. Organization-scoped installs work via skills-hub.ai organizations.
