加密是将数据到一种形式，称为密文不能轻易的转换理解 byunauthorized 人。解密是加密的 databack 转换其原始形式，以便它可以被理解的过程。使用的加密/解密航宇老作为沟通的艺术。在战时，可以采用一组密码，通常 incorrectlycalled 的"代码"，为了不让敌人从获得的传输内容。（从技术上讲，代码是代表没有保持秘密的意图信号的一种手段 ； 例子是莫尔斯电码 andASCII）。简单密码包括字母数字，字母在字母表中，therotation 和"争先恐后"的 voicesignals 通过反演的单边带频率的替代。更复杂的密码 workaccording 到复杂的计算机算法，重新排列数据 bitsin 数字信号。为了方便地恢复的加密信号的内容，则需要正确的解密密钥。"撤消"工作的 encryptionalgorithm 算法是关键。另外，一台计算机可用于尝试在"破"的密码。越复杂的加密算法，它变得对不能进入关键的通信进行监听的降解。加密/解密是无线通信中的 especiallyimportant。这是因为无线电路 areeasier"挖掘"硬连线的同行相比。然而，加密/解密是一个好主意，当进行任何种类的 sensitivetransaction，例如信用咭购买在线或在组织中的不同部门之间的陪伴着秘密的讨论。Strongerthe 密码 — — 那就是，难未经授权的人把它打破 — — 越好，一般。然而，作为加密/decryptionincreases 的力量，如此的成本。近几年来，在所谓的强加密的争议 hasarisen。这是指那收敛牢不可破没有解密密钥密码。虽然大多数公司及其客户认为它作为保守秘密和尽量减少欺诈的手段，作为一个潜在的手段，通过 whichterrorists 的一些政府认为强加密可能会逃避当局。解密密钥将存储在 asupposedly 安全的地方，仅由当局，使用只有支持捉拿法院命令使用。这项计划的反对者辩称罪犯可以砍进密钥托管数据库并非法获取、 偷窃，或改变钥匙。3.1EXISTING 系统在现有的系统中，加密密钥是发送文档。关键是与文档一起发送，如果任何用户都可以使用该密钥查看 encrypteddocument。这意
