Formatted transaction proofs

Formatted transaction proofs is a PGP-like message format used to conveniently share Monero transaction proofs without having to copy multiple fields.

Here is an example:

-----BEGIN OUTPROOF-----
Network: Monero Mainnet
Txid: 46d9f3eaf8d25b6a5d0847ad0beaece8b153d1b8c25ce317934ec17223025806
Address: 463o7kTG4n2AEHNhhV91BK7kZsKd4vRh78xt6LM7Px7o3cp5eZgyuyLHVAWeEkfLcoC78WMZuJ3xZ1SiM4RhbciCB8b8pGS

A small donation.
-----BEGIN OUTPROOF SIGNATURE-----

-----END OUTPROOF SIGNATURE-----

To learn how to verify formatted transaction proofs in Feather, see: Verify transaction proof.

For developers:

Formatted transaction proofs can be parsed using this regular expression:

(Newlines added for readability)

-----BEGIN (?<type>\w+)-----\n
Network: (?<coin>\w+) (?<network>\w+)\n
Txid: (?<txid>[0-9a-f]{64})\n
(Address: (?<address>\w+)\n)?
\n?
(?<message>.*?)\n
-----BEGIN \1 SIGNATURE-----\n
\n?
(?<signature>.*?)\n
-----END \1 SIGNATURE-----

Where:

• type is one of [SpendProof, OutProof, InProof]
• coin is Monero
• network is one of [Mainnet, Stagenet, Testnet]
• txid is a 64 character hexstring
• address is a valid Monero address for the given network.
  • MUST be present if type is OutProof or InProof.
  • MUST NOT be present if type is SpendProof.
• message is an optional arbitrary length message that may contain newlines
• signature is the proof signature
  • SHOULD be split into chunks of 64 characters over multiple lines
