Decrypting

In the meantime – but also in general – the proffered advice to use end-to-end encrypted (E2E) text and voice communication apps makes sense, as it will prevent attackers’ from decrypting any intercepted communication.

A fragment of the DeCSS code, which can be used by a computer to circumvent a DVD's copy protection DeCSS was one of the first free computer programs capable of decrypting content on a commercially produced DVD video disc.

In the late 1990s, groups such as the Censorware Project began reverse-engineering the content-control software and decrypting the blacklists to determine what kind of sites the software blocked.

The access point ensures the text was encrypted with the correct key by decrypting it with its own key.

The Feistel structure ensures that decryption and encryption are very similar processes—the only difference is that the subkeys are applied in the reverse order when decrypting.

The high-level, strategic nature of the intelligence obtained from Tutte's crucial breakthrough, in the bulk decrypting of Lorenz-enciphered messages specifically, contributed greatly, and perhaps even decisively, to the defeat of Nazi Germany.

The seed value serves as the cryptographic key for decrypting the ciphertext stream.

When round keys are short, this can be achieved by simply exhaustively decrypting the ciphertext pairs one round with each possible round key.
