+ examples of how to use the public_key API. Keys and certificates

+
+ <p>Note that some shell printouts, in the following examples,

+ <section>
+ <title>PEM files</title>
+ <p> Pulic key data (keys, certificates etc) may be stored in PEM format. PEM files
+ comes from the Private Enhanced Mail Internet standard and has a
+ structure that looks like this:</p>
+
+ <code>&lt;text&gt;
+ -----BEGIN &lt;SOMETHING&gt;-----
+ &lt;Attribute&gt; : &lt;Value&gt;
+ &lt;Base64 encoded DER data&gt;
+ -----END &lt;SOMETHING&gt;-----
+ &lt;text&gt;</code>
+
+ <p>A file can contain several BEGIN/END blocks. Text lines between
+ blocks are ignored. Attributes, if present, are currently ignored except
+ for <c>Proc-Type</c> and <c>DEK-Info</c> that are used when the DER data is
+ encrypted.</p>

+ DESCRIPTION
+ "Denotes a generic transport address.
+
+ A TransportAddress value is always interpreted within the
+ context of a TransportAddressType or TransportDomain value.
+ Every usage of the TransportAddress textual convention MUST
+ specify the TransportAddressType or TransportDomain object
+ which provides the context. Furthermore, MIB authors SHOULD
+ define a separate TransportAddressType or TransportDomain
+ object for each TransportAddress object. It is suggested that
+ the TransportAddressType or TransportDomain is logically
+ registered before the object(s) which use the
+ TransportAddress textual convention if they appear in the
+ same logical row.
+
+ The value of a TransportAddress object must always be
+ consistent with the value of the associated
+ TransportAddressType or TransportDomain object. Attempts
+ to set a TransportAddress object to a value which is
+ inconsistent with the associated TransportAddressType or
+ TransportDomain must fail with an inconsistentValue error.
+
+ When this textual convention is used as a syntax of an
+ index object, there may be issues with the limit of 128
+ sub-identifiers specified in SMIv2, STD 58. In this case,
+ the OBJECT-TYPE declaration MUST include a 'SIZE' clause
+ to limit the number of potential instance sub-identifiers."
