The German Lorenz cipher machine, used in World War II for encryption of very high-level general staff messages
The Ancient Greek scytale, probably much like this modern reconstruction, may have been one of the earliest devices used to implement a cipher.- File:Nsa-enigma.jpgThe Enigma machine, used in several variants by the German military between the late 1920s and the end of World War II, implemented a complex electro-mechanical cipher to protect sensitive communications. Breaking the Enigma cipher at Polish Biuro Szyfrów, and the subsequent large-scale decryption of Enigma traffic at Bletchley Park, was an important factor contributing to the Allied victory.
- File:Smartcard.JPGA credit card with smart card capabilities. Smart cards attempt to combine portability with the power to compute modern cryptographic algorithms.
Padlock icon from the Firefox web browser, meant to indicate a page has been sent in SSL or TLS-encrypted protected form. But note that a properly subverted browser might mislead a user by displaying some similar icon when a transmission is not being protected by SSL or TLS. Security is not a straightforward issue.
