Using the Smartex Key Utilities Library

This is the Smartex API utilities library. It is used to :

• Create keys
• Retrieving public keys
• Create a SIN to use when retrieving tokens from the Smartex API
• Sign a payload to use in the X-Signature header field of a Smartex API request.

Quick Start

Installation

To use the library in your project clone the github repository and include the smartex.h header. This will enable you to access the following functions :

int generatePem(char **pem) // creates an ECKEY and sets the value of pem to the PEM encoding of the key
int getPublicKeyFromPem(char *pemstring, char **pubkey) //takes a pem string and sets the value of pubkey to the compressed public key extracted from the pem
int generateSinFromPem(char *pem, char **sin) //gets the base58 unique identifier associated with the pem
int signMessageWithPem(char *message, char *pem, char **signature) //sets signature to the signature of the sha256 of the message

API Documentation

API Documentation is available on the Smartex site.
