The concatenation of two digitally signed CRLs is not a
valid digitally signed CRL.  Some applications may
happen to have code to explicitly support this hack, but
that ability could actually be a security hole as an enemy
could concatenate an outdated and a current CRL, fooling
such applications into thinking the revocations in the old
CRL still apply (Which would be relevant if a CA
temporarily "revokes" half-issued certificates as part of its
procedures).

Hi all,

on various sources on the internet I found that it is possible to
concatenate two X509 CRL's together.

cat file1.pem file2.pem>  combined.pem

However, if I run
openssl crl -in combined.pem -text -noout
I see only the revoked certificates from file1.pem

Is this not supported? Should I use a different command? Is this a bug?

Thanks for your help,
Olivier
