<section1 topic='Public Key Publication via PEP' anchor='usecases-pub'>
|
||||
<p>An entity SHOULD use &xep0163; to publish all its long-term public keys via its own server.</p>
|
||||
<p>If the pubkeys PEP node does not exist already then the entity MUST create it. In this case, the entity SHOULD specify that items published to the node are persistent and that the keys will only be pushed to subscribers whenever new keys are published (i.e. not when subscribers become newly available or when a new subscription is created). If the user wants to control access to his/her identity (see <link url='#security'>Security Considerations</link>) then the entity MUST also specify an appropriate access model other than "Open". The entity MAY create the node by including a <configure/> element when publishing a key for the first time.</p>

<p>If the pubkeys PEP node does not exist already then the entity MUST create it. In this case, the entity SHOULD specify that items published to the node are persistent and that the keys will only be pushed to subscribers whenever new keys are published (i.e. not when subscribers become newly available or when a new subscription is created). If the user wants to control access to his/her identity (see <link url='#security'>Security Considerations</link>) then the entity MUST also specify an appropriate access model other than "Open". The entity MAY create the node by including a <configure/> element when publishing a key for the first time (note: this functionality is not yet supported by &xep0060;).</p>
|
||||
<p>The entity can update the keys that the node contains at any time. The value of the 'id' attribute of each <item/> element SHOULD be set to the fingerprint of the public key. i.e., the SHA256 hash (see &nistfips180-2;) of the key's normalized <KeyValue/>, <PGPData/> or <X509Data/> element (all character data <em>between</em> all elements MUST be removed and the XML MUST be converted to canonical form - see &w3canon;). Thus subscribers are able to request a single key by specifying its fingerprint (for example, when a subscriber is using the &xep0116; protocol).</p>
|
||||
<p>Each public key MUST be wrapped in a <KeyInfo/> element as specified in &w3xmlsig;. Each <KeyInfo/> element published using PEP MUST contain a <KeyName/> element with a unique (for the user) name to allow the key to be referenced by other XMPP Extension Protocols (for example, &xep0136;). The name MAY be the same as the value of the 'id' attribute. However, if two <KeyInfo/> elements contain the same public key in different formats (for example, an X.509 certificate may contain an RSA key), then the name of the two keys SHOULD be the same.</p>
