(1) This key would allow the government to decrypt messages as needed, purportedly after seeking and obtaining a warrant.(2) the computer can be used to encrypt and decrypt sensitive transmissions(3) Second, when they cannot decrypt the alien code, he gives her the key to the mystery.(4) Since the eavesdropper doesn't know the starting point, he can't decrypt the message.(5) But once you have the right key, it takes less than a fraction of a second to prove that the key is the correct key: All you do is decrypt the message.(6) Everybody will know the information has come from you because only your public key can decrypt a message that has been encrypted using your private key.(7) Failure to comply with a decryption notice will be a criminal office, unless the individual concerned can prove he or she did not have the ability to decrypt the message for any reason, such as losing the password.(8) It should be easy to encrypt and decrypt messages with the key (which must be kept secret) but difficult to do so without it.(9) Otherwise, he can merely decrypt the message without any additional steps or effort.(10) The Aegis system allows a user to encrypt or decrypt a message by just hitting a button and entering a password, and the company says the password part of the process may be phased out soon.(11) the computer can be used to encrypt and decrypt sensitive transmissions(12) Another thing that will come along - probably after more than a decade or two - is quantum cryptanalysis, where you would use a quantum computer to decrypt existing codes.(13) But he's just as excited describing decryption as he is about his first surfing trip to the Pacificu2026(14) By 1944, over 4,000 German messages were being decrypted daily at Bletchley Park.(15) Many historians think that a secret Soviet message sent in 1945 (later decrypted by the Venona project) identifies Hiss by a code name.(16) Equally, the German Navy passed on decrypts of Allied traffic to Japan after 9 December 1941 only in its own cipher because of suspicions about Anglo-American inroads into Japanese systems.
