In cryptography what is ciphertext
In cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information. Encryption does not itself prevent interference but denies the intelligible conte… Webciphertext: [noun] the enciphered form of a text or of its elements — compare plaintext.

WebAn example This example uses the common unix utility "md5sum", which hashes the data on stdin to a 128 bit hash, displayed as 32 hex digits. Assume the password is "mysecretpass" and both the client and the server know this.The client connects to the server. The server makes up some random data, say "sldkfjdslfkjweifj ”.The server sends this data to client. WebWhat is 'Ciphertext' Definition: Cipher is an algorithm which is applied to plain text to get ciphertext. It is the unreadable output of an encryption algorithm. The term "cipher" is …
WebIn cryptology, the discipline concerned with the study of cryptographic algorithms, a cipher is an algorithm for encrypting and decrypting data. Symmetric key encryption, also called secret key encryption, depends on the use of ciphers, which operate symmetrically. Webcipher, any method of transforming a message to conceal its meaning. The term is also used synonymously with ciphertext or cryptogram in …
WebCiphertext, or encrypted text, is a series of randomized letters and numbers which humans cannot make any sense of. An encryption algorithm takes in a plaintext message, runs the … WebConfusion in a symmetric cipher is obscuring the local correlation between the input ( plaintext) and output ( ciphertext) by varying the application of the key to the data, while diffusion is hiding the plaintext statistics by spreading it over a larger area of ciphertext. [2] Although ciphers can be confusion-only ( substitution cipher, one ...
