Abstract
Efficient certificate revocation list (CRL) processing is disclosed. A desired modification to an encoded CRL is determined. A computing device sequentially processes, during a first pass, a first CRL stream comprising the CRL to identify a CRL length difference between the CRL and a modified CRL based on the desired modification. The computing device sequentially processes, during a second pass, a second CRL stream comprising the CRL. The computing device, during the second pass, streams a modified encoded header portion to a modified CRL stream that identifies a new length of the modified CRL based on the length difference, streams a modified encoded CRL entries portion comprising a plurality of CRL entries to the modified CRL stream that contains the desired modification, and streams a modified encoded trailer portion to the modified CRL stream that contains a new digital signature based on the desired modification.
