Measurements

Supported claims

• The pinned legacy vector keys and signatures match byte for byte.
• Only randomization elements zero through fifteen affect observable results.

Explicit nonclaims

• SHA-256 compatibility
• a legacy hardware verifier
• synthesis, timing, route, or card behavior

Tools

• HashSigsRS source: 2d315dd4168804b7cbc51c51a1bf7ca27bf74140
