crypto-analyzer
Cryptographic implementation analysis and validation for encryption algorithms, key sizes, and certificate management
npx skills add a5c-ai/babysitter --skill crypto-analyzer --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Crypto Analyzer Skill ## Purpose Analyze and validate cryptographic implementations to ensure proper algorithm usage, key sizes, certificate validity, and compliance with cryptographic best practices and standards. ## Capabilities ### Encryption Implementation Analysis - Analyze symmetric encryption usage (AES, ChaCha20) - Review asymmetric encryption implementations (RSA, ECDSA) - Check encryption mode selection (GCM, CBC, CTR) - Validate initialization vector (IV) handling - Verify padding schemes - Identify insecure encryption patterns ### Algorithm Strength Validation - Check algorithm deprecation status - Validate against NIST recommendations - Compare with FIPS 140-3 requirements - Assess quantum resistance readiness - Flag weak or deprecated algorithms - Recommend algorithm upgrades ### Key Size Verification - Validate RSA key lengths (minimum 2048-bit) - Check ECC curve selections - Verify symmetric key sizes - Assess key derivation functions - Check PBKDF2/scrypt/bcrypt parameters - Validate key stretching implementations ### Deprecated Algorithm Detection - Identify MD5 and SHA-1 usage - Flag DES and 3DES usage - Detect RC4 stream cipher - Find weak random number genera

What does the crypto-analyzer skill do?
Cryptographic implementation analysis and validation for encryption algorithms, key sizes, and certificate management
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill crypto-analyzer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
