keys

[solid]

Hi, I have the following question: If I encrypted some text with the
public key K, and tried to decrypt it with a wrong key (i.e. a key
which is NOT the corresponding private key), will I get an exception,
or is there is a boolean function to test whether the right key has
been used?

The only "test" is that the output of decryption is what you wanted.
If the algoritm was able to determine whether a key was right or not
it would make cracking it much easier.
