Thanks for responding. Following is the output printed by openssl
./openssl req -in csr.csr -noout -text
Version: 0 (0x0)
Subject Public Key Info:
Public Key Algorithm: id-ecPublicKey
Public-Key: (256 bit)
ASN1 OID: prime256v1
X509v3 Key Usage: critical
Signature Algorithm: ecdsa-with-SHA256
Please share is there any issue with these parameters?
