I am generating a KeyPair for ECC from curve 'secp128r1' using openssl
Steps I followed :
first I generated a private key using the command
openssl ecparam -genkey -name secp128r1 -noout -out private.pem
then i viewed the corresponding public key using the command
openssl ec -in private.pem -text -noout
which showed an output as :
read EC key
Private-Key: (128 bit)
priv:

30:a8:a5
ASN1 OID: secp128r1
I want explicitly x and y components from the public key generated here, please can anyone suggest the correct way of doing this ?
The above public key is 264 bits long, hence cannot take(/split) it as is
Thanks
