A cipher is an algorithm that performs decryption or encryption, a series of precise steps that can be followed by a process. An optional, less general term is encipherment. While using a cipher the original information is called plaintext, and encrypted form as ciphertext. Answer: A Explanation: The strict comparison operator returns true only if the operand are of the same type and content matches. When the switch statement is executed, the value of the expression is calculated and compared to the case labels, and looks for a case whose expressions produce the same value after evaluations (where the comparison is determined by the === operator).

Rebecca N. Wright, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 II.B Brute Force Attacks. Brute force attacks are ciphertext-only attacks or known-plaintext attacks in which the decryption algorithm is used as a “black box” to try decrypting a given ciphertext with all possible keys until, in the case of a ciphertext-only attack, a meaningful message is found In cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher. Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it. Oct 24, 2018 · Just as there are characteristic letter frequencies, there are also characteristic patterns of pairs of adjacent letters, called digrams (groups of 2 letter) and trigrams (groups of 3 letters). The frequency of appearance of letter groups can be used to match up plaintext letters that have been separated in a ciphertext. Attention reader!
