ACE20 and hashing algorithm

Question

I have a secure website behind an Cisco ACE20 using A2(3.2). Everything is working great. Only that now I need to renew my certificate. When creating the CSR and sending it to my CA I get this warning:
"Alert: Your CSR has been signed using the MD5 hashing algorithm. While the MD5 hashing algorithm is not optimal it will not prevent you from using this CSR to enroll for your SSL certificate. VeriSign best practices recommend that you use a different hashing algorithm for the signature. CSR Information"
Anybody know if it is possible to use SHA instead of MD5 or what can I do in this case?

Answer 1

I dont think you can chnage the signing method for CSRs on the ACE directly. But i would use something like OpenSSL to generate the CSR for SHA.
http://gnuwin32.sourceforge.net/packages/openssl.htm
openssl req -out c:\CSR.csr -new -newkey rsa:2048 -nodes -keyout c:\privateKey.key -sha1
The above will load a wizard format questionare for your CSR parameters similar to the ACE.
You can then upload your key, and cert when you get it to the ACE afterwards.
