<p>The KeyName element contains a string value (in which white space is
significant) which may be used by the signer to communicate a key
identifier to the recipient. Typically, KeyName contains an identifier
related to the key pair used to sign the message, but it may contain

a distinguished name (DN), an email address, etc.)</p>

several signatures in a document might use a key verified by an X.509v3

RetrievalMethod element instead of including the entire chain with a

<p>A Key Agreement algorithm provides for the derivation of a shared secret key based on
a shared secret computed from certain types of compatible public keys from both the sender
and the recipient. Information from the originator to determine the secret is indicated by
an optional OriginatorKeyInfo parameter child of an AgreementMethod element while that associated
with the recipient is indicated by an optional RecipientKeyInfo. A shared key is derived from
this shared secret by a method determined by the Key Agreement algorithm.</p>

used as a stand-alone XML document, be placed within an application
document, or appear inside an EncryptedData or Signature element as
