Re: [openssl-users] Custom lastUpdate in CRL

[Jakob Bohm]

Interestingly, it is part of standard (automated) operations
here.  Specifically, we use it to verify that data from the
past was actually signed with certificates that were valid at
that (past) point in time.

It is not an ideal interface, but seems reliable in the
controlled environment where it is used.

Hi Jakob,
 Thanks. It solved my problem for now. I agree with your suggestion.
In our scenario this would be a regular thing for coming years and will
not be seen as standard way for operations.

apart from certificates.
Seems like 1.0-1 does not have it. Any pointers to how I can
achieve this using
OpenSSL(version) or another utility, preferably on Linux.

For such tasks, I currently use the faketime utility program
to run the openssl command line tool in a context with the
data artificially set to the desired time in the past.

I have previously suggested that an "as of" time argument
be added to certificate and signature validation operations,
and your use case suggests the same for issuance and signing
operations as well.

In fact, it seems the general solution (in future OpenSSL
updates) would be for all operations that use the "current
time/date" to accept an alternative value of that as an
argument.
