Cipher text into plain text
WebEncryption is converting plain text into ciphertext. The working is shown below: Input : 1.Plain text that has to be converted into ciphertext. 2.A KEY to encrypt the plain text Output: Ciphertext We have a simple formula for encryption C = KPmod26 C is ciphertext, K is the key, P is the plain text vector. WebCryptography. Cryptography is the process of converting between readable text, called plaintext, and an unreadable form, called ciphertext . This occurs as follows: The sender converts the plaintext message to ciphertext. This part of the process is called encryption (sometimes encipherment ).

WebOnce the length of the secret key is known, the cipher text is rewritten into a corresponding number of columns, with a column for each letter of the key. Each column is then made up of plaintext that’s been encrypted by one Caesar cipher. The code-breaker then breaks the cipher text in a similar way to a Caesar cipher. WebApr 1, 2012 · The algorithm you're describing is known as a generalized Caesar cipher. The congruence relation that ciphers text is C = rP + s (mod 26) where P is the plain text, r is a multiplier and s is the shift. In the situation you describe, you have a …
