|
||
|
||
<p>When the public key is in DER-encoded PKCS#1 ASN.1 format, it is
|
||
recommended to use <code>ring::signature::verify()</code> with
|
||
<code>ring::signature::RSA_PKCS1_*</code>, because <code>ring::signature::verify()</code>
|
||
will handle the parsing in that case. Otherwise, this function can be used
|
||
to pass in the raw bytes for the public key components as
|
||
<code>untrusted::Input</code> arguments.</p>
|
||
|
||
<p><code>params</code> determine what algorithm parameters (padding, digest algorithm,
|
||
key length range, etc.) are used in the verification. <code>msg</code> is the message
|
||
and <code>signature</code> is the signature.</p>
|
||
|
||
<p><code>n</code> is the public key modulus and <code>e</code> is the public key exponent. Both are
|
||
interpreted as unsigned big-endian encoded values. Both must be positive
|
||
and neither may have any leading zeros.</p>

<h2>Search Tricks</h2>
|
||
|
||
<p>
|
||
Prefix searches with a type followed by a colon (e.g.
|
||
<code>fn:</code>) to restrict the search to a given type.
|
||
</p>
|
||
|
||
<p>
|
||
Accepted types are: <code>fn</code>, <code>mod</code>,
|
||
<code>struct</code>, <code>enum</code>,
|
||
<code>trait</code>, <code>type</code>, <code>macro</code>,
|
||
and <code>const</code>.
|
||
</p>
|
||
|
||
<p>
|
||
Search functions by type signature (e.g.
|
||
<code>vec -> usize</code> or <code>* -> vec</code>)
