38 - Passphrase-protected private key
BIP: 38 Layer: Applications Title: Passphrase-protected private key Author: Mike Caldwell Aaron Voisine Comments-Summary: Unanimously Discourage for implementation Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0038 Status: Draft (Some confusion applies: The announcements for this never made it to the list, so it hasn't had public discussion) Type: Standards Track Created: 2012-11-20 License: PD ==Abstract== A method is proposed for encrypting and encoding a passphrase-protected Bitcoin private key record in the form of a 58-character Base58Check-encoded printable string. Encrypted private key records are intended for use on paper wallets and physical Bitcoins. Each record string contains all the information needed to reconstitute the private key except for a passphrase, and the methodology uses salting and ''scrypt'' to resist brute-force attacks. The method provides two encoding methodologies - one permitting any known private key to...
39 - Mnemonic code for generating deterministic keys
BIP: 39 Layer: Applications Title: Mnemonic code for generating deterministic keys Author: Marek Palatinus Pavol Rusnak Aaron Voisine Sean Bowe Comments-Summary: Unanimously Discourage for implementation Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0039 Status: Proposed Type: Standards Track Created: 2013-09-10 ==Abstract== This BIP describes the implementation of a mnemonic code or mnemonic sentence -- a group of easy to remember words -- for the generation of deterministic wallets. It consists of two parts: generating the mnemonic and converting it into a binary seed. This seed can be later used to generate deterministic wallets using BIP-0032 or similar methods. ==Motivation== A mnemonic code or sentence is superior for human interaction compared to the handling of raw binary or hexadecimal representations of a wallet seed. The sentence could be written on paper or spoken over the telephone. This guide is meant to be...
75 - Out of Band Address Exchange using Payment Protocol Encryption
BIP: 75 Layer: Applications Title: Out of Band Address Exchange using Payment Protocol Encryption Author: Justin Newton Matt David Aaron Voisine James MacWhyte Comments-Summary: Recommended for implementation (one person) Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0075 Status: Final Type: Standards Track Created: 2015-11-20 License: CC-BY-4.0 ==Abstract== This BIP is an extension to BIP 70 that provides two enhancements to the existing Payment Protocol. # It allows the requester (Sender) of a PaymentRequest to voluntarily sign the original request and provide a certificate to allow the payee to know the identity of who they are transacting with. # It encrypts the PaymentRequest that is returned, before handing it off to the SSL/TLS layer to prevent man in the middle viewing of the Payment Request details. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MA...
123 - BIP Classification
BIP: 123 Title: BIP Classification Author: Eric Lombrozo Comments-Summary: No comments yet. Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0123 Status: Active Type: Process Created: 2015-08-26 License: CC0-1.0 GNU-All-Permissive ==Abstract== This document describes a classification scheme for BIPs. BIPs are classified by system layers with lower numbered layers involving more intricate interoperability requirements. The specification defines the layers and sets forth specific criteria for deciding to which layer a particular standards BIP belongs. ==Copyright== This BIP is dual-licensed under the Creative Commons CC0 1.0 Universal and GNU All-Permissive licenses. ==Motivation== Bitcoin is a system involving a number of different standards. Some standards are absolute requirements for interoperability while others can be considered optional, giving implementors a choice of whether to support them. In order to have a BIP process which more closely ...
