Hello,

I have a question for a security junkie.

In a typical PKI model, a sender of a message may encrypt the message using a public key, and the recipient can decrypt the message using his private key.

My question is: Can a person decrypt the message using the public key? Apparently the answer is no, but I don't understand why this is. It seems to me that if you have the means to encrypt something, than you should be able to decrypt it with the same info.

Thanks!
