AES Encryption ECB Mode with PKCS7 Padding

Duplicates the following C# code:

public static byte[] DecryptBySymmetricKey(string encryptedText, byte[] key)
  {
     string keyAsBase64 = Convert.ToBase64String(key);

     byte[] dataToDecrypt = Convert.FromBase64String(encryptedText);
     var keyBytes = key;
     AesManaged tdes = new AesManaged();
     tdes.KeySize = 256;
     tdes.BlockSize = 128;
     tdes.Key = keyBytes;
     tdes.Mode = CipherMode.ECB;
     tdes.Padding = PaddingMode.PKCS7;
     ICryptoTransform decrypt__1 = tdes.CreateDecryptor();
     byte[] deCipher = decrypt__1.TransformFinalBlock(dataToDecrypt, 0, dataToDecrypt.Length);
     tdes.Clear();
     string EK_result = Convert.ToBase64String(deCipher);
     return EK_result;
}

Go

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    crypt := chilkat.NewCrypt2()

    // In the C# code above that is to be duplicated here, use the base64 encoded key.
    keyAsBase64 := "..."
    encryptedBytesAsBase64 := "...."

    crypt.SetKeyLength(256)
    crypt.SetCryptAlgorithm("AES")
    crypt.SetCipherMode("ecb")
    crypt.SetPaddingScheme(0)
    crypt.SetEncodedKey(keyAsBase64,"base64")

    crypt.SetEncodingMode("base64")

    // Pass the base64 representation of the encrypted data.
    // (The EncodingMode indicates you are passing base64.)
    EK_result := crypt.DecryptStringENC(encryptedBytesAsBase64)

    fmt.Println(*EK_result)

    crypt.DisposeCrypt2()
