# Cryptography Discovery

Cryptography Discovery auto-activates when working with TLS, certificates, PKI, encryption, and related security tasks. It points Claude Code to the relevant cryptography subskills for setup, troubleshooting, and best practices.

**Install:**

```bash
npx degit https://github.com/rand/cc-polymath/tree/main/skills/discover-cryptography ~/.claude/skills/discover-cryptography
```

## README

# Cryptography Skills Discovery

Provides automatic access to comprehensive cryptography and security skills.

## When This Skill Activates

This skill auto-activates when you're working with:
- TLS, SSL, mTLS
- Certificates and PKI
- Encryption and decryption
- Hashing and signing
- Key management
- HTTPS configuration
- Certificate authorities
- Cryptographic algorithms
- Security best practices

## Available Skills

### Quick Reference

The Cryptography category contains 7 skills:

1. **pki-fundamentals** - PKI, certificate authorities, X.509, trust chains
2. **tls-configuration** - TLS 1.2/1.3 setup, cipher suites, server config
3. **ssl-legacy** - SSL 2.0/3.0, TLS 1.0/1.1, deprecation, migration
4. **sni-routing** - Server Name Indication, multi-domain TLS hosting
5. **certificate-management** - Certificate lifecycle, Let's Encrypt, automation
6. **cryptography-basics** - Symmetric/asymmetric encryption, hashing, signing
7. **crypto-best-practices** - Security patterns, common mistakes, anti-patterns
