🔐 Radikant-SASL-C

Simple Authentication and Security Layer

Introduction

Radikant SASL is a minimal SASL driver only supporting SCRAM and uses Radikant Crypto as a backend for cryptographic operations. It was created soley to support the Radikant PostgreSQL driver.

SCRAM Example

int Perform_Authentication()
{
    // 1. Create a SASL context
    sasl_context_t *ctx = sasl_context_create();
 
    // 2. Configure the context
    sasl_config_t config = {
        .mechanism = SASL_MECH_SCRAM_SHA256,
        .role = SASL_ROLE_CLIENT
    };
    
    sasl_error_t err = sasl_context_set_config(ctx, &config);
 
    // 3. Set credentials
    sasl_credentials_t creds = {
        .username = "user",
        .password = "pencil"
    };
 
    err = sasl_context_set_credentials(ctx, &creds);
 
    // 4. Start the authentication process
    sasl_buffer_t client_out = {0};
    err = sasl_start(ctx, SASL_MECH_SCRAM_SHA256, NULL, &client_out);
 
    return (err == SASL_OK) ? 0 : -1;
}
