Hi,

in our tests we noticed an OpenSSL peculiarity that that might
affect OpenCA, too. I don't have the time right now, so I cannot
test this currently with the CVS head, but I am quite sure that
the problem exists there, too.

Imagine you have a CA policy that demands sha1WithRSAEncryption as
signature algorithm througout your CA. (You don't seriously want
MD5, do you?)

You can set

default_md = sha1

in your OpenSSL configuration file for OpenCA and you will get
the desired hash algorithm in certificates.

However, if you also want sha1WithRSAEncryption in CRLs, it doesn't
seem to be possible to configure this in the openssl.cnf file. In fact,
I found out that it is seemingly necessary to explicitly call

openssl ca -gencrl -md sha1 ...

in order to get sha1WithRSAEncryption instead of the default
md5WithRSAEncryption.

Some people (like us) might want to be able to configure this in
the CA configuration. Perhaps I missed something, but I think
currently it is not possible set this up.
Should it be added to config.xml?

cheers

Martin
