|

<p><code>aad</code> is the additional authenticated data (AAD), if any.</p>
|
||
<p>On input, <code>in_out[ciphertext_and_tag]</code> must be the ciphertext followed
|
||
by the tag. When <code>open_within()</code> returns <code>Ok(plaintext)</code>, the plaintext
|
||
will be at <code>in_out[0..plaintext.len()]</code>. In other words, the following
|
||
two code fragments are equivalent for valid values of
|
||
<code>ciphertext_and_tag</code>, except <code>open_within</code> will often be more efficient:</p>
|
||
<pre><code class="language-skip">let plaintext = key.open_within(aad, in_out, cipertext_and_tag)?;
|
||
</code></pre>
|
||
<pre><code class="language-skip">let ciphertext_and_tag_len = in_out[ciphertext_and_tag].len();
|
||
in_out.copy_within(ciphertext_and_tag, 0);
|
||
let plaintext = key.open_in_place(aad, &mut in_out[..ciphertext_and_tag_len])?;
|
||
</code></pre>
|
||
<p>Similarly, <code>key.open_within(aad, in_out, 0..)</code> is equivalent to
|
||
<code>key.open_in_place(aad, in_out)</code>.</p>
|
||
<p>When <code>open_in_place()</code> returns <code>Err(..)</code>, <code>in_out</code> may have been
|
||
overwritten in an unspecified way.</p>
|
||
<p>The shifting feature is useful in the case where multiple packets are
|
||
being reassembled in place. Consider this example where the peer has
|
||
sent the message “Split stream reassembled in place” split into
|
||
three sealed packets:</p>
|
||
<pre><code class="language-ascii-art"> Packet 1 Packet 2 Packet 3
|
||
Input: [Header][Ciphertext][Tag][Header][Ciphertext][Tag][Header][Ciphertext][Tag]
|
||
| +--------------+ |
|
||
+------+ +-----+ +----------------------------------+
|
||
v v v
|
||
Output: [Plaintext][Plaintext][Plaintext]
|
||
“Split stream reassembled in place”
|
||
</code></pre>
|
||
<p>This reassembly be accomplished with three calls to <code>open_within()</code>.</p>
