in cryptography, a cipher is a digital security algorithm that encrypts and decrypts data. homepage → the page people see when they visit your site's root domain. read more about the homepage. flex-shrink → the flex-shrink css property defines how much an element shrinks relative to ...
In cryptography, cipher text (ciphertext) is data that has beenencrypted. Cipher text is unreadable until it has been converted intoplain text(decrypted) with akey. About the author Webopedia Staff Since 1995, more than 100 tech experts and researchers have kept Webopedia’s definitions, articles...

密码学Cryptography | 密码学(Cryptography)这一话题(向潜在敌人隐藏信息)已经存在了数千年。随着现代技术、计算机和电信的出现,它发生了巨大的变化。加密(encryption)是一种获取消息(称为明文 plaintext)并对其实施某个应用操作(称为密码或暗号 cipher)的行为。因此,在收到一条乱码、不可读的消息作为输出时,我们称为...

Most of them are mathematical in nature. Since matrices have unique and very powerful concept and can be easily understood so it could be applied as an efficient way for encrypting and storing text. This article describes some of the techniques of cryptography using matrices. The technique is ...
(algorithm, cryptography) Any procedure used incryptographyto convertplaintextintociphertext(encrypted message) in order to prevent any but the intended recipient from reading that data. Schematically, there are two classes of encryption primitives:public-key cryptographyandprivate-key cryptography; they ...
Cryptography deals with encrypting or encoding a piece of information (in a plain text) into a form that looks gibberish and makes little sense in ordinary language. This encoded message(also calledciphertext) can then be decoded back into a plain text by the intended recipient using a decoding...
