|
<p>AES IGE (Infinite Garble Extension) is a form of AES block cipher utilized in
|
|
OpenSSL. Infinite Garble refers to propagating forward errors. IGE, like other
|
|
block ciphers implemented for AES requires an initialization vector. The IGE mode
|
|
allows a stream of blocks to be encrypted or decrypted without having the entire
|
|
plaintext available. For more information, visit <a href="http://www.links.org/files/openssl-ige.pdf">AES IGE Encryption</a>.</p>
|
|
<p>This block cipher uses 16 byte blocks. The rust implementation will panic
|
|
if the input or output does not meet this 16-byte boundary. Attention must
|
|
be made in this low level implementation to pad the value to the 128-bit boundary.</p>
|
|
<h2 id="panics"><a class="doc-anchor" href="#panics">§</a>Panics</h2>
|
|
<p>Panics if <code>in_</code> is not the same length as <code>out</code>, if that length is not a multiple of 16, or if
|
|
<code>iv</code> is not at least 32 bytes.</p>
