Abstract
Embodiments of the present invention provide a compression capability for compressing a CRL, such as an X.509 CRL, stored as a file, data structure or data object in a computer system having a certification authority (CA) and a security client. An exemplary method provides for accessing the CRL contents including a certificate revocation record and performing compression procedure, such as a lossless compression procedure on the contents of the CRL. The compressed CRL contents can be stored in another file, data structure or data object. A request for the compressed CRL is from a security client whereupon the compressed CRL is returned to the security client by transferring the compressed CRL contents to the security client. The security can client un-compress the compressed CRL contents. In some cases the uncompressed CRL contents can be transferred to the security client. The compression procedure can further compress a body portion of the CRL and modify a header portion of the CRL to indicate that the body portion is compressed. The security client can read the header portion to determine that the CRL is compressed and can un-compresses the CRL.
