Examples

<?php

/**
 * Example of how to hook into the 'automator_mcp_public_key' filter.
 *
 * This example demonstrates how to modify the public key before it's used.
 * It might be useful to obfuscate or further process the key based on specific needs,
 * although modifying a public key directly is generally not recommended for security reasons.
 * This is more for demonstration of the hook's functionality.
 *
 * @param string $pem The public key in PEM format.
 * @param string $version The version of the public key.
 * @param array  $record_array An array representation of the public key record.
 * @return string The modified public key in PEM format.

    // In a real-world scenario, you'd have a more sophisticated logic here.
    // For this example, we'll just prepend a string to the PEM if the version is 'v2'.
    // This is purely illustrative and not a recommended security practice.
    if ( 'v2' === $version ) {
        $pem = "--- CUSTOM_MODIFICATION_FOR_V2 ---n" . $pem;
    }

    // You could also potentially log information about the key being used.
    error_log( "Automator public key used. Version: {$version}. Record ID: " . ( isset( $record_array['id'] ) ? $record_array['id'] : 'N/A' ) );

    // Always return the modified value.
    return $pem;
}

// Add the filter to WordPress.
// The '3' indicates that our callback function accepts 3 arguments ($pem, $version, $record_array).
