Secp256k1-zkp PHP Library
=========================

[](#secp256k1-zkp-php-library)

### Description

[](#description)

PHP library for parts of [libsecp256k1-zkp](https://github.com/mimblewimble/secp256k1-zkp).

### Installing

[](#installing)

Run the following command from the root of your project to install this library and configure your project to use it.

```
composer require nicolasflamel/secp256k1-zkp

```

### Usage

[](#usage)

After an `Secp256k1Zkp` object has been created, it can be used to perform all the secp256k1-zkp functions that this library implements.

The following code briefly shows how to use this library. A more complete example is available [here](https://github.com/NicolasFlamel1/Secp256k1-zkp-PHP-Library/tree/master/example).

```

```

### Functions

[](#functions)

1. Secp256k1-zkp constructor: `constructor(): Secp256k1Zkp`

    This constructor is used to create a `Secp256k1Zkp` object and it returns the following value:

    - `Secp256k1Zkp`: An `Secp256k1Zkp` object.
2. Secp256k1-zkp is valid private key method: `isValidPrivateKey(string $privateKey): bool`

    This method is used to check if a provided private key is valid and it accepts the following parameters:

    - `string $privateKey`: The private key to validate.

    This method returns the following values:

    - `bool`: `TRUE` if the private key is valid or `FALSE` if it is not.
3. Secp256k1-zkp get public key method: `getPublicKey(string $privateKey): string | FALSE`

    This method is used to get a provided private key's public key and it accepts the following parameters:

    - `string $privateKey`: The private key to get the public key for.

    This method returns the following values:

    - `string`: The private key's public key.
    - `FALSE`: Getting the public key failed.
4. Secp256k1-zkp add private keys method: `addPrivateKeys(string &$firstPrivateKey, string $secondPrivateKey): bool`

    This method is used to add two private keys and it accepts the following parameters:

    - `string &$firstPrivateKey`: The private key to add the second private key to. This variable will contain the sum of the private keys if the function returned `TRUE`.
    - `string $secondPrivateKey`: The private key to add to the first private key.

    This method returns the following values:

    - `bool`: `TRUE` if adding private keys was successful or `FALSE` if it failed.
5. Secp256k1-zkp get blinding factor method: `getBlindingFactor(string $blind, string $value): string | FALSE`

    This method is used to get the blinding factor from a provided blind and value and it accepts the following parameters:

    - `string $blind`: The blind to use.
    - `string $value`: The value to use. This must be a non-negative integer.

    This method returns the following values:

    - `string`: The blinding factor for the provided blind and value.
    - `FALSE`: Getting the blinding factor failed.
6. Secp256k1-zkp get commitment method: `getCommitment(string $blindingFactor, string $value): string | FALSE`

    This method is used to get the commitment for a provided value using a provided blinding factor and it accepts the following parameters:

    - `string $blindingFactor`: The blinding factor to use.
    - `string $value`: The value to commit. This must be a non-negative integer.

    This method returns the following values:

    - `string`: The commitment for the provided value using the provided blinding factor.
    - `FALSE`: Getting the commitment failed.
7. Secp256k1-zkp get Bulletproof method: `getBulletproof(string $blindingFactor, string $value, string $rewindNonce, string $privateNonce, string $message): string | FALSE`

    This method is used to get Bulletproof for a provided value committed with a provided blinding factor using a provided rewind nonce, private nonce, and message and it accepts the following parameters:

    - `string $blindingFactor`: The blinding factor use to commit the value.
    - `string $value`: The value committed to. This must be a non-negative integer.
    - `string $rewindNonce`: The rewind nonce to use.
    - `string $privateNonce`: The private nonce to use.
    - `string $message`: The message to use.

    This method returns the following values:

    - `string`: The Bulletproof for the provided value committed with the provided blinding factor using the provided rewind nonce, private nonce, and message.
    - `FALSE`: Getting the Bulletproof failed.
8. Secp256k1-zkp get private nonce method: `getPrivateNonce(): string | FALSE`

    This method is used to get a random private nonce that can be used when creating a partial single-signer signature and it returns the following values:

    - `string`: A private nonce.
    - `FALSE`: Getting a private nonce failed.
9. Secp256k1-zkp combine public keys method: `combinePublicKeys(array $publicKeys): string | FALSE`

    This method is used to get the combined public key for provided public keys and it accepts the following parameters:

    - `array $publicKeys`: The public keys to combine.

    This method returns the following values:

    - `string`: The combined public key.
    - `FALSE`: Combing public keys failed.
10. Secp256k1-zkp get partial single-signer signature method: `getPartialSingleSignerSignature(string $privateKey, string $message, string $privateNonce, string $publicKey, string $publicNonce): string | FALSE`

    This method is used to get the partial single-signer signature for a provided message signed with a provided private key using a provided private nonce, public key, and public nonce and it accepts the following parameters:

    - `string $privateKey`: The private key to use.
    - `string $message`: The message to sign.
    - `string $privateNonce`: The private nonce to use.
    - `string $publicKey`: The public key to use.
    - `string $publicNonce`: The public nonce to use.
