Convert PHP openssl_encrypt and openssl_decrypt to GO language [closed]

I’m having a challenge converting the PHP openssl_* functions to GO language. I want to be able to encrypt a text using PHP and decrypt it using GO. This is the PHP functions encryption and decryption:

<?php

function Encrypt($ClearTextData)
{
    $secretKey = 'RJBwYSb5dFcyqUEHD300jY9nhxmi6Lnx';
    try {
        $EncryptionKey = base64_decode($secretKey);
        $InitializationVector = openssl_random_pseudo_bytes(openssl_cipher_iv_length('AES-256-CBC'));
        $EncryptedText = openssl_encrypt($ClearTextData, 'AES-256-CBC', $EncryptionKey, 0, $InitializationVector);
        $data = base64_encode($EncryptedText . '::' . $InitializationVector);

        return $data;
    } catch (Exception $ex) {
        throw $ex;
    }
}

function Decrypt($CipherData)
{
    $secretKey = 'RJBwYSb5dFcyqUEHD300jY9nhxmi6Lnx';
    try {
        if (!$CipherData) {
            throw new ErrorException('Empty cipher string', 4004);
        }

        $EncryptionKey = base64_decode($secretKey);
        list($Encrypted_Data, $InitializationVector) = array_pad(explode('::', base64_decode($CipherData), 2), 2, null);
        return openssl_decrypt($Encrypted_Data, 'AES-256-CBC', $EncryptionKey, 0, $InitializationVector);
    } catch (Exception $ex) {
        throw $ex;
    }
}

I want to have the same functions in GO. The decrypt function in GO should be able to decrypt what has been encrypted in PHP
