Package pem implements the PEM data encoding, which originated in Privacy
Enhanced Mail. The most common use of PEM encoding today is in TLS keys and
certificates. See RFC 1421.

<p>
In the call graph viewer below, each node
is a function belonging to this package
and its children are the functions it
calls&mdash;perhaps dynamically.
</p>
<p>
The root nodes are the entry points of the
package: functions that may be called from
outside the package.
There may be non-exported or anonymous
functions among them if they are called
dynamically from another package.
</p>
<p>
Click a node to visit that function's source code.
From there you can visit its callers by
clicking its declaring <code>func</code>
token.
</p>
<p>
Functions may be omitted if they were
determined to be unreachable in the
particular programs or tests that were
analyzed.

<pre>type Block struct {
Type <a href="../../builtin/index.html#string">string</a> <span class="comment">// The type, taken from the preamble (i.e. &#34;RSA PRIVATE KEY&#34;).</span>

Bytes []<a href="../../builtin/index.html#byte">byte</a> <span class="comment">// The decoded bytes of the contents. Typically a DER encoded ASN.1 structure.</span>
}</pre>
<p>
A Block represents a PEM encoded structure.
</p>
<p>
The encoded form is:
</p>
<pre>-----BEGIN Type-----
Headers
base64-encoded Bytes
-----END Type-----
</pre>
<p>
where Headers is a possibly empty sequence of Key: Value lines.
</p>
<h3 id="Decode">func <a href="http://localhost:6060/src/encoding/pem/pem.go?s=2203:2251#L68">Decode</a></h3>
<pre>func Decode(data []<a href="../../builtin/index.html#byte">byte</a>) (p *<a href="index.html#Block">Block</a>, rest []<a href="../../builtin/index.html#byte">byte</a>)</pre>
<p>
Decode will find the next PEM formatted block (certificate, private key
etc) in the input. It returns that block and the remainder of the input. If
no PEM data is found, p is nil and the whole of the input is returned in
rest.
