Verify Salvium message signatures
SaLv... address instead.
This tool verifies cryptographic signatures created by Salvium wallets using the sign command.
It supports both V1 (legacy) and V2 (domain-separated) signature formats, and can detect whether
the spend key or view key was used to create the signature.
Important: Currently, Salvium wallets sign messages using
CryptoNote (legacy) keys only. Use your SaLv... address for verification,
not your SC1... CARROT address.
