RE: DCM SSL sha1 / sha256 cert issues

Brad,

I did verify the cert via browser with both IE and Chrome.
This only verifies port 443.
I was looking for test/verification for the non-HTTP apps listed in DCM with the cert assigned to them.

No CAs in the chain? I've seen that once before for an FTP site using
SSL. I actually just imported that as a CA and it worked. Something odd
for sure

Self-signed certs in this case?

Another things you can do is enter the URL in your browser. I know chrome can return a LOT of information about your cert.

In our case.

QSH
openssl s_client -connect icomstest.pencor.com:443

Returns the below info.

I'm concerned about the verify error.
Correct SSL Protocol, SSL cypher are shown.
Cert is shown, but SHA needs to be interpreted.

Brad,
Yes, I just thought I'd piggy back on the thread without de-railing
it. I remembered that Scott wrote a UNIXCMD thing. I'm just googling
stuff on connecting via OpenSSL now.

Peter,

I believe Scott meant you could use OpenSSL to grab the certificate
from a server and then with that tell what kinds it is.

We have something similar in our SSL documentation here:
http://docs.bvstools.com/home/ssl-documentation/openssl

Adding an openSSL hook to HTTPAPI and/or our GETURI product is also
something that's been on my todo list for a while as I'm just not
satisfied with the APIs much any more. I mean it's ok, but using
openSSL would sure be a nice addition. I had to do the same thing
with email years ago and one of my most used products was created. :)

Hi Scott,
Could you point me at some material so that I might try writing a
program that connects to a 3rd part server via OpenSSL as an
alternative to HTTPAPI ?

Paul,

For server-type applications, you could connect with the openssl
command-line client. It can tell you all sorts of info about the
certs that it receives.

The same tool can be used to analyze a certificate from a file (on
your PC or the IFS, etc). You'd probably have to export it from the
DCM, but you could use this to find out whether it uses SHA256

You could also use it to connect to various services (Central,
Database, et al) to see what they're running.

Just a thought.

1) Within DCM, is there a method to see if a cert is SHA1 or SHA256?
I'm not seeing the sha details anywhere.

2) I need a tool or method to determine which cert is being used
by a
non HTTP SSL job/process.
