crypto's Issues

[Feature request] Implement AES-IGE

Hi there! First of all, love your lib. Just started getting into Deno myself and it's nice to see a good crypto library already exists. I'm working on porting another very large project to Deno, and it requires the AES-IGE block cipher. IGE isn't used much at all except by Telegram for their MTProto protocol, but it would be really helpful to me to have it available in your library.

Why my AES result wrong?

My typescript AES result is different from golang language, typescript is client language, and golang is my server language.

Then I try some AES website like https://the-x.cn/en-US/cryptography/Aes.aspx, and I found golang AES result is same as the website AES result.

Here is my code.

const te = new TextEncoder();
const key = te.encode("1234567899999999");
const data = te.encode("1234");

const iv = new Uint8Array(16)
for (let i = 0; i < key.length; i++) {
	iv[i] = key[i]
}

const cipher = new Cbc(Aes, key, iv, Padding.PKCS7);
const encrypted = cipher.encrypt(data);
const base64 = Base64.encode(encrypted)

The typescript AES result = CbV6UFL7HC7H1smYlwliVg==
The golang AES result = S7gxtGIbOdtmzhn4vAW13A==
The website AES result = S7gxtGIbOdtmzhn4vAW13A==

It's so strange and I am checking my code, does my code has any problem?

error: Invalid key size (must be either 16, 24 or 32 bytes)

Hello, I just see this Deno module and I want to use it.

here is my code:

import { Aes } from 'https://deno.land/x/[email protected]/aes.ts';
import { Cbc, Padding } from 'https://deno.land/x/[email protected]/block-modes.ts';

export default function encrypt(encData: string, encKey: string) {
  const te = new TextEncoder();

  const key = te.encode(encKey);
  const data = te.encode(encData);
  const iv = new Uint8Array(16);

  const cipher = new Cbc(Aes, key, iv, Padding.PKCS7);

  return cipher.encrypt(data);
}

however, running

console.log(encrypt("ABC123456", "VeryStrongPassword"));

return this error

error: Uncaught Error: Invalid key size (must be either 16, 24 or 32 bytes)
      throw new Error("Invalid key size (must be either 16, 24 or 32 bytes)");

How do I fix this? New to Deno.

Thank you (and sorry in case this is a foolish question).
