Decrypting and Understanding 'Cipher Text'
Symmetric, encryption algorithms (ciphers) for text, a means of encryption. When text is converted, to characters, items and objects, in its encrypted format, not able to be opened or made any sense of. This is typically done for security purposes. Cipher Text is a term used in cryptography and data, file and information, transmission, encryption. It deals with the transformational process taking plaintext, using an algorithm, the so-called cipher, to enable it.
Encrypted data is typically unreadable, non-legible, not decipherable unless it has been encrypted/decoded, with a key. Characters of bits is readable, unless you have the converter in place to decipher it. See elsewhere secret keys, encryption and decryption. They are economic, easy and fast to use, even for large quantities of data. It is quite secure. Security, secret keys for encryption and decryption should be shared with caution and changed frequently, similar to for passwords. To enable users to access and read it, they do need to know and have the key, in order to do so. Find commands in the System.Security.Cryptography namespace (RijndaelManaged, AESManaged, DES, TripleDES, RC2).
Key Exam Points
-
User and data security, review relevant chapter from the manual.
-
For the exam study related terms and case scenarios, creating solutions, practices and practice tests, multiple choice questions.
