Hello Dave,

Thanks for responding. Following is the output printed by openssl

./openssl req -in csr.csr -noout -text

Certificate Request:
    Data:
        Version: 0 (0x0)
        Subject: CN=eccert/unstructuredName=xxxx
        Subject Public Key Info:
            Public Key Algorithm: id-ecPublicKey
                Public-Key: (256 bit)
                pub:

                ASN1 OID: prime256v1
        Attributes:
        Requested Extensions:
            X509v3 Key Usage: critical
                Digital Signature
    Signature Algorithm: ecdsa-with-SHA256


Please share is there any issue with these parameters?

Thanks,
Rajeswari.
