dashmsg: a cross-platform tool to Sign and Verify Dash messages via Private Key and/or Payment Address

To update or switch versions, run webi dashmsg@stable.

Cheat Sheet

dashmsg allows you to sign and verify, like dash-cli, but without needing a full dash node with rpc to do so.

  • Generates secp256k1 ECDSA keys (WIF)
  • Signatures output as Base64
  • Verifies signatures by Payment Address (PubKeyHash)

How to generate a new Private Key (WIF)

# dashmsg gen <key>
dashmsg gen priv.wif
dashmsg gen > pirv.wif

How to sign a message

# dashmsg sign <priv key> <data or file>
dashmsg sign ./priv.wif 'vote2022-alice|bob|charlie'

How to verify a signature

# dashmsg verify <payment address> <message> <signature>
dashmsg verify 'Xn4A2vv5fb7LvmiiXPPMexYbSbiQ29rzDu' \
    'vote2022-alice|bob|charly' \
