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:
    00:9f:bf:2b:bd:06:86:3a:a1:bc:7c:3e:90:57:40:
    f4:bc
    pub:
    04:04:ce:24:34:d4:cb:f2:58:94:2f:8a:5f:06:d7:
    3f:ed:5a:50:ef:fb:cc:b7:49:62:16:62:9e:aa:d5:
    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
