Thank you, that works! For so

Hi
I recently migrated an application from OpenSSL 1.1.1 to OpenSSL 3.0, and
I'm wondering how best to handle DSA signatures - specifically, the 'r' and
's' values - in OpenSSL 3.0.
In OpenSSL 1.1.1, it was pretty easy:
DSA_do_sign() - gets you a DSA_SIG
DSA_SIG_get0()

start with an 8 byte sequence that matches the regular expression:

Of course that should be: "the first 4 bytes", which corresponds to "the
first 8 hex digits"
Duh!

When computing DSA signatures, the first eight bytes of the signature
appear to follow a rather predictable pattern, which I am concerned about.
I've tested this to be so using two slightly different input texts:
1. "Mary had a little lamb"

Steve,
That did it!! Thanks a bunch

Nils,

The private key I used was one read in when I generated a DSA

Any thoughts? Same routine I used for

What I've seen so far with openssl is that there seems to be 10,000 ways
to do the same thing so I want to make sure I understand how to do a DSA
signature. My questions are as follows:
1. Do you need a separte cert for signing RSA DSA? I created certs with
the following shell (create parms and c
