Bitcoin is a decentralized digital currency that operates on a peer-to-peer network of computers. Unlike traditional currencies, Bitcoin does not rely on any central authority or intermediary to issue or validate transactions. Instead, transactions are recorded in a public ledger called the blockchain, which is maintained by a network of nodes (computers) running the Bitcoin software.
A Bitcoin address is a string of alphanumeric characters that represents a destination for a Bitcoin payment. You can think of it as your account number or email address for Bitcoin. A Bitcoin address is derived from a public key, which is a cryptographic code that can be used to verify the authenticity of a signature. A public key, in turn, is derived from a private key, which is a secret code that can be used to sign transactions and prove ownership of bitcoins. A private key is like your password or PIN for Bitcoin.
Bitcoin Address Utility is an open-source program that allows you to do various useful functions with Bitcoin addresses and keys, such as convert them between different formats, encrypt and decrypt them, and print them as paper wallets. This program was started by Casascius, a well-known Bitcoin enthusiast who also created the physical Casascius coins, and is available on GitHub at ( It is written in C# and is based on Microsoft's .NET / Visual Studio toolchain. Bitcoin Address Utility runs natively for Windows, and also runs on Linux and Mac using Mono.
How to Download and Install Bitcoin Address Utility
To use Bitcoin Address Utility, you need to have either Windows, Linux, or Mac OS with .NET or Mono installed. .NET is a software framework developed by Microsoft that supports various programming languages and applications. Mono is an open-source project that provides cross-platform compatibility for .NET applications.
You can download the latest version of Bitcoin Address Utility from ( The download link is located under the "Releases" section on the right side of the page. You will see a file named "BtcAddress.zip", which contains the executable file "BtcAddress.exe" and some other files. You can extract the zip file to any folder you like.
To run the program, simply double-click on the "BtcAddress.exe" file. You will see a window with four tabs: Address Utility, Base58 Calculator, Key Combiner, and Paper Wallet. Each tab provides different functions that we will explain in the next section.
How to Use Bitcoin Address Utility for Various Purposes
How to create new Bitcoin addresses and private keys
The Address Utility tab allows you to. create new Bitcoin addresses and private keys. You can choose from different types of addresses, such as P2PKH (Pay to Public Key Hash), P2SH (Pay to Script Hash), and Bech32 (SegWit). You can also choose the network (mainnet or testnet) and the compression (compressed or uncompressed) of the keys. To generate a new address and key pair, simply click on the "Generate" button. You will see the address, the public key, and the private key in various formats, such as hexadecimal, base58, and WIF (Wallet Import Format). You can copy or save these values as you wish.
How to convert between different formats of addresses and keys
The Address Utility tab also allows you to convert between different formats of addresses and keys. For example, you can convert a P2PKH address to a P2SH address, or a compressed public key to an uncompressed one. To do this, simply enter the value you want to convert in the appropriate field, and click on the "Convert" button. You will see the converted value in the corresponding field. You can also use the "Validate" button to check if an address or a key is valid.
How to encrypt and decrypt private keys with BIP 0038
BIP 0038 is a Bitcoin Improvement Proposal that defines a standard for encrypting and decrypting private keys with a passphrase. This adds an extra layer of security to your private keys, as you need both the encrypted key and the passphrase to access your bitcoins. To encrypt or decrypt a private key with BIP 0038, go to the Base58 Calculator tab. Enter the private key in the "Base58 data" field, and enter the passphrase in the "BIP 0038 Passphrase" field. Then, click on the "Encrypt" or "Decrypt" button, depending on what you want to do. You will see the encrypted or decrypted private key in the "BIP 0038 data" field.
How to perform elliptic-curve arithmetic on keys and addresses
Elliptic-curve arithmetic is a branch of mathematics that is used in cryptography and Bitcoin. It allows you to perform operations on keys and addresses, such as adding, subtracting, multiplying, and dividing them. This can be useful for advanced users who want to create custom transactions or scripts. To perform elliptic-curve arithmetic on keys and addresses, go to the Key Combiner tab. Enter the values you want to operate on in the "Operand 1" and "Operand 2" fields, and choose the operation from the drop-down menu. Then, click on the "Calculate" button. You will see the result in the "Result" field.

A paper wallet is useful for storing your bitcoins offline, as it is immune to hacking, malware, or hardware failure. However, you need to be careful not to lose or damage your paper wallet, as there is no way to recover it if you do.
How to generate and print paper wallets with QR codes

You can also enter your own address and private key if you want, or use the ones generated by Bitcoin Address Utility. To print your paper wallets, click on the "Print" button. You will need a printer connected to your computer.
How to scan and import paper wallets into a software wallet

Some examples of such apps are Electrum, Mycelium, and BRD. To scan and import your paper wallet, open your software wallet app and choose the option to scan a QR code. Then, point your camera at the QR code of your paper wallet that contains your private key. Your software wallet app will recognize your private key and import it into your wallet. You will then be able to access your bitcoins from your software wallet.
