auditing-randomness-and-nonce-quality skillA

auditing-randomness-and-nonce-quality is agent-read markdown (skill) from unboundcompute/security-agent-skills: Audit security-sensitive values for weak randomness: a non-cryptographic generator, a predictable or constant seed, a reused nonce or initialization vector, or an output too short to resist guessing, feeding a value whose only defense is unpredictability. Covers session and authentication tokens, password-reset and verification links, cross-site-request tokens and one-time codes, and cryptographic nonces or initialization vectors, drawn from a statistical generator instead of a cryptographic one.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add unboundcompute/security-agent-skills/auditing-randomness-and-nonce-quality@git:20260821.57dfaf1
Exact content
mdr add unboundcompute/security-agent-skills/auditing-randomness-and-nonce-quality@sha256:7dab58707dd2f85a

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
