Hi,

I am working on the digital certificate support for our VPN gateway and it
works fine with RSA SHA1 (hash algo). When I am using MD5 hash algo, I get
an error on remote for signature verification failed. I am using BCM5820
crypto engine and I have tried using OpenSSL also.

What is difference between Signature for SHA1 hash and MD5 hash?

How I can resolve this issue?

thanks
Rajendra
