cryptography clips for working devs. ~30 seconds each.

SSH, signing, PGP, certificates, TLS — the math underneath the tools you already use. No jargon-dump. No "magic happens here." Just the part that makes the next bug make sense.

Built for the kind of engineer who's typed ssh-keygen -t ed25519 a hundred times and only ever vaguely wondered what the 25519 meant.

# in scope
topics = [
    "key exchange",
    "signing & verification",
    "hash functions in the wild",
    "TLS & certificate chains",
    "PGP, SSH, age, sigstore",
    "why this primitive, not that one",
]
audience = "backend engineers, SREs, security-curious devs"
depth     = "deeper than a tutorial, shallower than a paper"

What this channel is not: news, opinions, threat-intel, CVE coverage, "5 best VPNs," paid sponsorships.

Every clip is AI-assisted in production (script, voice, captions). The choice of topic, the angle, and the technical claims are human-edited before publish. Each video carries TikTok's AI-generated-content label.
