Hello all

 I have generated a X.509 certificate using bouncy castle generator and i used the \
ECDSA as the signature algorithm in the certificate.

The certificate is already generated, but when i verify it using bouncy castle only \
signature exception appears, which mean the certificate has an invalid signature.

So, What is the problem now, how the certificate generated successfully and then when \
i verify it gives me invalid signature?

Can you help me please.

Thanks in advance
BEST REGARDS

Ayman
