Hi,
I have a certificate in pem format issued to me by a CA, and a private key
which I generated. Since I need to do domain key signing (dkim), I was
asked to
use the followng openssl command to generate the public key:
$ openssl rsa -in rsa.private -out rsa.public -pubout -outform PEM
Since I've already gotten a public key from the CA is there anyway that I
can extract the
info in my public key to produce the same result as the above openssl
command?
The following is what I need to get out from my public key (openssl x509 -in
public.key -nnout), for ex:
Modulus (1024 bit):
00:a0:f3:2a:3a:ac:38:6c:36:2c:14:7d:54:77:ec:

Exponent: 65537 (0x10001)
Thanks any help is much appreciated.
