From the OpenSSL RSA man page: To print out the components of a private key to standard output:
openssl rsa -in key.pem -text -noout Not explicitly in the man page, but from reading it, it appears to get the components of the private key, the following should work: openssl rsa -in key.pem -pubin -pubout -text -noout Lou Artificial Intelligence is no match for Natural Stupidity Artificial Intelligence is no match for Natural Stupidity On Tue, Jun 26, 2012 at 6:01 AM, gialloporpora <gialloporp...@gmail.com> wrote: > > Dear all, > I am trying to learn how S/MIME encryption/digital signing works. > > I would like to show the numerical values assigned to my private and public > key. > > I have converted my personal certificate from p12 to pem, in this way: > > openssl pkcs12 -in mycert.p12 -out mycert.pem > > Now, I have used this command to show the modulus of the private/public key: > > openssl rsa -in mykey.pem -noout -modulus > > and I see an hexadecimal value, now I know that my public key is a data like > this: > > (exp1, modulus) > > > > where modulus is the value above.
