Thank you .
Can i include the public key generated below to a certificate and if
possible how can it be done.
openssl rsa -pubout -in priv.pem -out pub.pem

I have used this command to obtain public key in hex but, how to get
the individual value of public key ( n,e).

In fact, you asked for the modulus (n), and that's what you obtained.
To get the entire public key, including the public exponent (e), use this:
openssl x509 -pubkey -noout -in /home/certificates/MTA/MTA_DEVICE.cert.pem |
openssl rsa -noout -text -pubin
Then, do whatever is necessary to convert this output in something
useful for you.
