Forge.
Hands-on tooling for post-quantum cryptography. Build the right keygen commands, walk through signing, compare signature sizes, and get post-quantum operations working in OpenSSL. Command recipes and interactive walkthroughs; OpenSSL does the real work.
Tools
keygen
Build the right OpenSSL keygen command for ML-KEM and ML-DSA.
signatures
Signing walkthrough with size comparisons (simulated in-browser).
compare
ECDSA vs ML-DSA vs SLH-DSA: sizes and timings.
openssl
PQ operations via the OpenSSL 3.5+ CLI — setup, recipes, troubleshooting.
More tools are planned — a certificate inspector and a PQC migration decision tree are on the list. What gets built first is driven by what people ask for.
What this isn't
Not a replacement for primary sources. Every tool links to the NIST or IETF document that's actually authoritative; Forge just makes the operations runnable. If a sandbox here disagrees with the spec, the spec wins.
Standards Forge tracks
NIST FIPS 203, FIPS 204, FIPS 205; the OpenSSL 3.5 PQ release line; the IETF LAMPS work on PQ in X.509; and whatever the Vault lists as currently relevant.
