<p>To share the file the entity converts the HTTPS URL, the key and the IV to an aesgcm:// URL. Both IV and key are converted to their hex representation of 24 characters and 64 characters respectively and concatenated for a total of 88 characters (44 bytes). The IV comes first followed by the key. The resulting string is put in the anchor part of the aesgcm URL.</p> <p>To share the file the entity converts the HTTPS URL, the key and the IV to an aesgcm:// URL.

<p>The sending entity MAY also generate a thumbnail as a JPEG data uri and include that in the same message. The aesgcm:// and the data:image/jpep, are seperated by a new line character. The message SHOULD NOT include anything else. The JPEG thumbnail SHOULD be kept small (approximately 5KiB) to not run into into stanza size limitations. As a result the resulting thumbnail is considered to only be a very blury, very rough representation of the image.</p> <p>The sending entity MAY also generate a thumbnail as a JPEG data uri and include that in the same message.
