I am currently working on an assignment that requires digitally signing a document, and verifying the digital certificate.

I have been able to achieve the same using Crypt::DSA module, wherein DSA is used to digitally sign the doc.

However, since the requirement is to use PKI, I would need to use Crypt::RSA for digital signing and verification. Also, please let me know how can I capture the public keys of recipient and the private key of the host machine, so that I can create and verify digital signatures using RSA.

Thanks.
