In cryptography, the EFF DES cracker (nicknamed "Deep Crack") is a machine built by the Electronic Frontier Foundation (EFF) in 1998, to perform a brute force search of the Data Encryption Standard (DES) cipher's key space – that is, to decrypt an encrypted message by trying every possible key. The aim in doing this was to prove that the key size of DES was not sufficient to be secure.

(pl) EFF DES破解机（英語：EFF DES cracker）是电子前哨基金会（EFF）在1998年建造的机器，用于暴力破解美国政府的数据加密标准，即DES加密算法，昵称“深译”（英語：Deep Crack）。这台机器能够对DES密钥空间中所有的密钥逐一进行尝试，从而将密文破解，其目的在于证明DES的密钥长度不足，不能保证安全。本机器的相关技术资料，包括原理图、电路图、芯片VHDL源代码、模拟器源代码，均被电子前哨基金会公开发表在《破解DES》一书中，并使用了公有领域许可协议，允许任何人复制、使用与修改。为了避开美国政府的出口管制，源代码是以书本形式而不是电子形式发布的。书中的源代码含有机器可读的元数据，方便读者使用OCR将源代码录入计算机。 (zh) Em criptografia, o EFF DES cracker (apelidado de "Deep Crack") é uma máquina construída pela EFF para executar uma busca por ataque por força bruta do espaço de chave de cifragem do DES, para descriptografar e criptografar mensagens tentando todas as chaves possíveis. O motivo para fazer isso era provar que o a chave do DES não é longa o suficiente para ser considerada segura. (pt)
