This is probably a pretty basic question, but i'm new to encryption and openssl, so please forgive the fact that it's probably stupid.
I've got known private and public rsa keys in hex format, including all the parameters (n, p, q, etc.). I know that i can use genrsa to generate keys into a .pem file that can subsequently be passed to enc to encrypted some data. however, i need to be able to use the keys that i have been provided. is there a way to convert the hex values to the format that the .pem files should be in (or a way for enc to accept the hex values directly)?
i know 'openssl rsa -in key.pem -text' will do the reverse of what i want - i.e., give me a hex dump of the pem file. is there another utility or command to do what i need?
just to be absolutely clear, I would like to convert the sample public/private keys below to a format that i can supply to "openssl rsautl -encrypt -inkey keyfile.pem -in ..."
Thanks much for any support.
