The optional RSA 2048 signature is across the three certificates, the signature version and the
user-provided nonce
RSA PKCS#1v1.5 Sign {<Nonce (UINT64)> || <Signature Version (UINT32)> || <Cisco Root CA
2048 cert (DER)> ||
<Cisco subordinate CA (DER)> || <SUDI certificate (DER)> }
Cisco management solutions are equipped with the ability to interpret the above output. However,
a simple script using OpenSSL commands can also be used to display the identity of the platform
and to verify the signature, thereby ensuring its Cisco unique device identity.
