Jump to: , Bitcoin users may want to trade bitcoin directly with each other in what is known as an over-the-counter market.This topic is a guide on how to set up your online identity and includes some best practices for trading with others in the Bitcoin community.Contents 1 2 3 4 Within the Bitcoin community, individuals should be careful with their security and identity, primarily for two reasons: The Bitcoin community uses a few tools to help protect privacy, and thus identity.The first and most important is a secure computer.Before proceeding please make sure you have completed the Securing Your Computer guide; this guide assumes that your computer is secure both physically and in software.If you are trading within Canada you are encouraged to use Interac e-transfer and Clearcoin (now closed) as outlined on this page.The first step is to create a cryptographically secure public-private key-pair.This will be used as the basis of keeping both your wallet (see Securing your wallet) and your identity secure.

Creating your first PGP key-pair A PGP key-pair serves two very important functions: This allows you to both conduct business privately (encryption), and give out promises that you cannot deny making (signature).Virtually all GNU/Linux distributions include GPG in their default configurations, but Microsoft Windows users will need to install additional software.On Windows, the recommend package that contains GPG is the Git package by the msysgit project.This package contains a collection of Unix tools that are very useful for any Windows installation.This option will install both Git and its supporting tools that include gpg into the Windows file PATH.This will enable any Windows application to access GPG.It is possible that some other software on your system has installed GPG before.If you think this may be the case, it is advised to use the search tool or command prompt to find or run GPG respectively.Once you have GPG installed on your system, it is recommended that you use Thunderbird that works on both Windows and Linux systems: Upon loading Enigmail, Thunderbird will ask you to make a new ‘identity,’ follow this wizard and you will have created your identity.

You should backup your private key in a secure place.Secondary, you should create a revocation certificate and store that in a different secure place (maybe print it out and store it in your fire safe)./wiki/Using_bitcoin-otc Use a strong and different password for each of these places, keeping your passwords in a secure place.This will allow other people in the community to track you across the different Bitcoin related sites.Also making identity theft online more challenging.Using a service such as Bitcoin OTC or CoinTouch, you can find friends of friends that trade crypto currency, and trade with them directly.Remember to verify the counterparty using more than one means of contact (e.g.Facebook message and phone call) The Bitcoin OTC acts as a secure 'Address Book' within the bitcoin community.One of the key features of the Bitcoin OTC is the Web of Trust, this allows users to 'rate' each other.One can have more confidence trading with a user that has many good ratings.This allows either party to go public if the trade has become sour and stops your trading partner from claiming the details of the agreement were somehow different.

Search the Bitcoin Forum for the username of the person that you are trading with.Check if the user has provided constructive and useful advice to other parties.And, most importantly, check for any claims that the user has scammed.bitcoin ticker for androidTrading might benefit from an escrow service such that bitcoins are disbursed only after contract terms have been met.dogecoin logoAdditionally, found in Bitcoin's community are trusted individuals willing to act as independent, third-party escrow brokers.litecoin optionsBitcoin Sign up or log in to customize your list.bitcoin hitting 10000_ Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top up vote 4 down vote favorite Both bitcoin and encrypted emailing are based on public key cryptography.bitcoin smtp

However, they use different implementations, so I assume that a public PGP key cannot be used as a bitcoin address directly.But would it be possible to convert a public PGP key to a bitcoin address in such a way that it can be accessed only with the corresponding private PGP key (or something derived from it)?bitcoin-qt wallet encryptionIf such an algorithm existed it would allow for sending coins to people without them knowing anything about Bitcoin, as long as they have a PGP key (e.g.bitcoin april 2013 crashfor giving someone a little incentive to learn something about Bitcoin).dogecoin value 2014cryptography address-generation up vote 3 down vote No, this is not possible.ethereum brokers

Recent GPG versions do have support for Elliptic Curve crypto, with associated EC keys.The EC curves supported there are different from the one used in Bitcoin, though (they don't have the same size, so they certainly can't be isomorphic).up vote down vote Yes, technically you could.Any 256 bit number can be used as a bit coin private key.If you hashed the PGP key with SHA256 you would have a private key that could be used for bitcoin.Really you'd be using your private PGP key as a brain wallet seed with very high entropy.Edit: With all that being said I still wouldn't do it.Your Answer Sign up or log in Sign up using Google Sign up using Email and Password Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.Browse other questions tagged cryptography address-generation or ask your own question._ Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top up vote 1 down vote favorite /en/download I also downloaded the PGP signed file that shows the SHA256 file signatures: /bin/bitcoin-core-0.12.1/SHA256SUMS.asc How do I verify this PGP signed file?
