Usage
To use BIP38 encryption, you need a private key in Wallet Import Format (WIF) and a passphrase.
The private key is a string of alphanumeric characters that allows you to access your cryptocurrency funds. The WIF format is commonly used to import private keys into wallet software.
The passphrase is a string of characters that you create and use as an additional layer of security. It is recommended to choose a strong passphrase that is not easily guessable.
To encrypt your private key using BIP38, you can use a BIP38 encryption tool or library. This tool will prompt you to enter your private key and passphrase, and it will generate an encrypted version of your private key.
This encrypted version of your private key is in the form of a QR code or a string of characters. It is important to keep this encrypted private key safe and secure, as it is your only way to access your cryptocurrency funds.
When you need to access your funds, you can use a BIP38 decryption tool or library to decrypt the encrypted private key. This tool will prompt you to enter the encrypted private key and your passphrase, and it will generate the original private key in WIF format.
Once you have the decrypted private key, you can import it into your wallet software or use it to sign transactions.
It is important to note that if you forget your passphrase, it will be impossible to recover the original private key. Therefore, it is crucial to choose a passphrase that you can remember but is not easily guessable by others.
Encrypting WIF with Passphrase and Address
BIP38 (Bitcoin Improvement Proposal 38) is a standard method for encrypting Bitcoin private keys using a passphrase and the associated address. This provides an additional layer of security to protect your cryptocurrency.
When you encrypt a Wallet Import Format (WIF) private key using BIP38, you add a passphrase that needs to be entered in order to decrypt the key and access the funds. This ensures that even if someone gets hold of your encrypted private key, they won’t be able to use it without knowing the passphrase.
To encrypt a WIF private key with BIP38, follow these steps:
- Generate a random passphrase that is strong and unique. This passphrase should not be easily guessable and should not be used for any other purpose.
- Obtain the address associated with the private key you want to encrypt. This is the public key hash representation of the address.
- Combine the WIF private key and the address to create an intermediate string.
- Derive an encryption key from the intermediate string using a key derivation function.
- Encrypt the WIF private key using the encryption key, generating an encrypted private key.
- Store the encrypted private key securely.
When you want to access the funds protected by the encrypted private key, you need to decrypt it using the passphrase. This process involves reversing the steps mentioned above:
- Enter the passphrase to obtain the encryption key.
- Decrypt the encrypted private key using the encryption key, retrieving the original WIF private key.
- Use the WIF private key to sign transactions and access the associated funds.
This encryption method adds an additional layer of security to your cryptocurrency holdings. Even if someone gains access to your encrypted private key, they cannot use it without the passphrase. It is important to choose a strong passphrase and keep it secure to prevent unauthorized access to your funds.
By encrypting your WIF private keys with a passphrase and the associated address, you can enhance the security of your cryptocurrency investments and ensure that your funds are protected.
Bip38 Versions
The Bip38 specification defines different versions of the encryption scheme, each with its own set of features and compatibility. These versions are denoted by a single byte prefix, known as the Bip38 Version Byte.
The Bip38 Version Byte is the first byte of the bip38EncryptPrivateKeyWif and is used to determine the encryption algorithm and other options used to encrypt the private key.
There are currently three defined versions:
- Version 0 (0x42): This is the original Bip38 version and supports both non-EC multiply mode and EC multiply mode.
- Version 1 (0x43): This version added support for the “Lot/Sequence number” option, which can be used to deter key reuse.
- Version 2 (0x44): This version added support for the “Ephemeral Public Key” option, which can be used to protect against side-channel attacks.
Each version has its own advantages and considerations, and it is important to use the version that best fits your needs and requirements.
| Version Byte | Supported Features |
|---|---|
| 0x42 |
|
| 0x43 |

|
As new versions of Bip38 are introduced, additional features and security enhancements may be added. It is important to stay updated with the latest version and use it to ensure the highest level of security for your encrypted private keys.
ScryptParams
The ScryptParams class is a helper class used by the this library for handling the scrypt parameters required for encryption and decryption of Bip38 encrypted private keys.
The scrypt algorithm is used in this library to derive a key from a passphrase, which is then used to encrypt and decrypt the private key. The scrypt parameters include the cost factor, block size, and parallelization factor, which determine the computational cost and memory requirements of the scrypt algorithm.
By using the bip38encryptprivatekeywif method with a passphrase and ScryptParams, users can encrypt their private keys in a way that makes them resistant to brute-force attacks. The scrypt parameters can be set to require a large amount of computational resources and memory, making it difficult for attackers to guess the passphrase and derive the encryption key.
The ScryptParams class provides methods for setting and getting the scrypt parameters. Users can customize the cost factor, block size, and parallelization factor based on their desired level of security and available computational resources.
Here is an example code snippet showing how to use the ScryptParams class:
ScryptParams params = new ScryptParams();
params.setCostFactor(16384);
params.setBlockSize(8);
params.setParallelizationFactor(1);
String passphrase = "myPassphrase";
String encryptedPrivateKey = this.bip38encryptprivatekeywif(privateKey, passphrase, params);
In the example above, the ScryptParams object is created and the cost factor, block size, and parallelization factor are set. Then, the bip38encryptprivatekeywif method is called with the private key and passphrase, along with the ScryptParams object, to encrypt the private key using the specified scrypt parameters.
API
An Application Programming Interface (API) is a set of rules and protocols that allows different software applications to communicate with each other. In the context of cryptocurrency, an API can be used to interact with different services and platforms, such as wallets or exchanges, in order to perform various actions or retrieve information.
When it comes to Bip38 and protecting your cryptocurrency, the use of an API can be particularly beneficial.
