Review the paragraph from the code book.
ordinarily, if alice wants to use rsa to encrypt a message to bob, she looks up his public key and then applies rsa's one-way function to the message. conversely, bob decrypts the ciphertext by using his private key to reverse rsa's one-way function. both processes require considerable mathematical manipulation, so encryption and decryption can, if the message is long, take several minutes on a personal computer.
which transitional word has the same meaning as "on the other hand”?
ordinarily
conversely
manipulation
encryption
