WebIf you can make sense of what is written, then it is in plaintext. Ciphertext, or encrypted text, is a series of randomized letters and numbers which humans cannot make any sense of. … WebThe plaintext message is read from the user using getline, which reads input until a newline character is encountered. A vector of integers called randoms is defined, which will hold the random numbers generated for each character in the plaintext message. A loop iterates over each character in the plaintext message.

WebSep 12, 2024 · Plaintext - Data before encryption, often text but not always. Could be a photograph or other file Encryption - Transforming data into ciphertext, using a cipher. Encoding - NOT a form of encryption, just a form of data representation like base64. Immediately reversible.

WebAn affine cipher, (like a shift cipher), is an example of a substitution cipher: In encryption using a substitution cipher, each time a given letter occurs in the plaintext, it always is replaced by the same ciphertext letter. For example, the plaintext letter ‘e’ might be replaced by the ciphertext letter ‘K’ each time it occurs.
