<p>AES ECB, CBC, XTS, CTR, CFB, GCM and other conventional symmetric encryption
|
|
modes are found in <a href="../symm/index.html"><code>symm</code></a>. This is the implementation of AES IGE and key wrapping</p>
|
|
<p>Advanced Encryption Standard (AES) provides symmetric key cipher that
|
|
the same key is used to encrypt and decrypt data. This implementation
|
|
uses 128, 192, or 256 bit keys. This module provides functions to
|
|
create a new key with <a href="struct.AesKey.html#method.new_encrypt"><code>new_encrypt</code></a> and perform an encryption/decryption
|
|
using that key with <a href="fn.aes_ige.html"><code>aes_ige</code></a>.</p>
|
|
<p>The <a href="../symm/index.html"><code>symm</code></a> module should be used in preference to this module in most cases.
|
|
The IGE block cipher is a non-traditional cipher mode. More traditional AES
|
|
encryption methods are found in the <a href="../symm/struct.Crypter.html"><code>Crypter</code></a> and <a href="../symm/struct.Cipher.html"><code>Cipher</code></a> structs.</p>
