Base64- Encoded X.509 Certificate Format
X.509 certificate format is an emerging certificate standard. It is part of the OSI
group of standards. X.509 certificates are very clearly defined using a notation
called ASN.1 (Abstract Syntax Notation 1) which specifies the precise kinds of
binary data that make up the certificate.
ASN.1 can be encoded in many ways, but the emerging standard is an encoding
called DER (Distinguished Encoding Rules), which results in a compact binary
certificate.
For e-mail exchange purposes the binary certificate is often Base64 encoded,
resulting in an ASCII text document that looks like the following:
-----BEGIN CERTIFICATE-----

-----END CERTIFICATE-----
CiscoWorks requires the Certificates to be uploaded in this format.
Other certificate formats such as PKCS#7 also have similar formats. Hence it is
Note
important that you confirm with the CA the format of the certificate, and request
specifically for Base64 Encoded X.509Certificates formats.
