Signing overview
Qsign binds a document to a signer identity with a lattice signature standardized in NIST FIPS 204. RSA and ECDSA signatures can be forged by a sufficiently large quantum computer. ML-DSA cannot, so envelopes signed here stay trustworthy long after classical signatures stop being evidence.
