Hi,
In public key cryptography, a message encrypted with a private key can
be decrypted with a public key, and so I tried:
openssl rsautl -encrypt -inkey private-key -in message -out cryptogram
openssl rsautl -decrypt -inkey public-key -pubin -in cryptogram
The problem is that the second command gives me:
A private key is needed for this operation
Why can't one decrypt with a public key?
I do realize that I can convince the recipient of the message that the
message is indeed mine by signing the message.
Thanks,
Irek
