BIP: 137 source Layer: Applications Title: Signatures of Messages using Private Keys Authors: Christopher Gilliard Status: Deployed Type: Specification Assigned: 2019-02-16 License: BSD-2-Clause Table of ContentsAbstractCopyrightMotivationSpecificationBackground on ECDSA SignaturesConventions with signatures used in BitcoinProcedure for signing/verifying a signatureSample Code for processing a signatureBackwards CompatibilityImplicationsAcknowledgementsReferences Abstract This document describes a signature format for signing messages with Bitcoin private keys. The specification is intended to describe the standard for signatures of messages that can be signed and verified between different clients that exist in the field today. Note: that a new signature format has been defined which has a number of advantages over this BIP, but to be backwards compatible with existing implementations this BIP will be useful. See BIP 322 [1] for full details on the new signature scheme....
