Asymmetric cryptography

Can we encrypt a message with private key of host A and the can the host B decrypt the message using public key of A? How t0 term this rather than used in hybrid cryptography?

Re: Asymmetric cryptography

Yes you can -- its something like digital signature...Its not so much secure (for data confidentiality) - every one can decrypt message with public key

BUT it says yes this message was encrypted with private key of host A so sender is host A - so such scenario is used for proof of identity...

Second scenario with asymmmetric cryptography: message is encrypted with public key of host A and can be decrypted only with private key of host A so only host A can decrypt message - its used when confidentiality is needed

M.

hope that helps rate if it does
