you see, as Nils, pointed out your blob is not in asn.1 der format (not
starting with 0x30..). since ecdsa_sig is BIGNUM *r, *s; you can try
using the BN_bin2bn() function to directly convert your blob to BIGNUM.
you'll need to do this twice, once for r & once for s. Since Nil
Thanks I found it already! Now everything works fine

Hi again,
Yes, ecdsa_sig is defined like

Hi Jim,
First of all thanks for your fast answer.
But still it don't understand 100%!
If have an SignatureValue which is
724PlFGHTTL1cFlLFU6g6UetcPVBEAN6oNpogAUx3rgELFH86gA+NqvjVf316zek
But how can I but this now into an ECDSA_SIG struct?

Can you maybe give me a short example?
Thanks and regards

what he means is that there is no asn.1 sequence, just the 2 integers
concat'ed. normally you would've expected to have something like this:

When I decode this SignatureValue with the following function

{
BIO *b64, *bmem;
char *buffer = (char *)malloc(length);
memset(buffer, 0, length)
Does really no one have any idea?
