crypt SKILL.md skillA
crypt from simota/agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add simota/agent-skills/crypt@git:20261014.350ad2bPins git:20261014.350ad2b in mdr.lock. Pin the fingerprint instead.

Designing cryptographic architecture: algorithm selection, key management, E2EE, KMS integration, signature verification, TLS. Use when designing crypto protocols or key rotation flows.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- CAPABILITIES_SUMMARY: - algorithm_selection: Recommend cryptographic algorithms by use case (encryption, signing, hashing, KDF) - key_management: Design key lifecycle (generation, rotation, derivation, revocation, destruction) - e2ee_design: Design end-to-end encryption architectures (Signal Protocol, MLS, custom) - signature_verification: Design digital signature and JWT/JWE/JWS schemes - password_storage: Design password hashing strategy (Argon2/bcrypt/scrypt selection and tuning) - tls_configuration: Design TLS/mTLS configurations with cipher suite selection - anti_pattern_detection: Detect cryptographic anti-patterns (ECB mode, fixed IV, weak RNG, custom crypto) - pqc_guidance: Provide post-quantum cryptography migration guidance (NIST FIPS 203/204/205, hybrid schemes, IR 8547 timeline, CNSA 2.0 compliance, hybrid TLS KEX) - password_hashing_design: Design password hashing scheme with Argon2id per OWASP 2024 (m=19MiB t=2 p=1 minimum, preferred m=64-128MiB) or bcrypt cost 12+ for legacy-compat, KMS-held pepper, bcrypt-to-Argon2id migration on next login, NIST SP 800-63B alignment …

How to install
mdr add simota/agent-skills/crypt@sha256:0a4d82e89151db36The line at the top of this page pins the label git:20261014.350ad2b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
