Generate Bitcoin Address From Public Key

Mar 03, 2019 What is a private key exactly? Private keys are based on secret 256-bit long string of letters and numbers which are randomly selected when you create a bitcoin wallet. This address enables you to send the bitcoins to a recipients destination address. Any of these will generate the same address and thus be able to spend the money owned by that address. Since 2^160 is so large, however, it would take a near-eternity to find any collisions. Whether two private keys can generate the same public key is another question.

Generate Private Key From Bitcoin Address

Bitcoin is a cryptocurrency, a form of electronic cash. It is a decentralized digital currency without a central bank or single administrator that can be sent digitally from user-to-user on the peer-to-peer Bitcoin network without the need for intermediaries.
A Bitcoin Address is an ID of 26-35 alphanumeric numbers, that represents a possible destination for an (incoming) Bitcoin payment for example to a Bitcoin Wallet. A Bitcoin wallet address, which is a hash of the corresponding public key, always starts either with number 1 or with the number 3.
