With the advent of computing, the term plaintext expanded beyond human-readable documents to mean any data, including binary files, in a form that can be viewed or used without requiring a key or other decryption device. Information—a message, document, file, etc.—if to be communicated or stored in an unencrypted form is referred to as ...
One of the most famous military encryption developments was the Caesar cipher, in which a plaintext letter is shifted a fixed number of positions along the alphabet to get the encoded letter. A message encoded with this type of encryption could be decoded with a fixed number on the Caesar cipher.
In computing, plain text is a loose term for data (e.g. file contents) that represent only characters of readable material but not its graphical representation nor other objects (floating-point numbers, images, etc.). It may also include a limited number of "whitespace" characters that affect simple arrangement of text, such as spaces, line ...
With the original design of email protocol, the communication between email servers was in plain text, which posed a huge security risk. Over the years, various mechanisms have been proposed to encrypt the communication between email servers. Encryption may occur at the transport level (aka "hop by hop") or end-to-end.
5 Plaintext vs plain text. 2 comments. Toggle the table of contents. ... Have gone ahead and tried to disentangle cleartext, plain text, and plaintext. Lots of fiddly ...
Known-plaintext: the attacker has a set of ciphertexts to which they know the corresponding plaintext; Chosen-plaintext attack: the attacker can obtain the ciphertexts corresponding to an arbitrary set of plaintexts of their own choosing Batch chosen-plaintext attack: where the cryptanalyst chooses all plaintexts before any of them are encrypted.
^ The "classic" format is plain text, and an XML format is also supported. ^ Theoretically possible due to abstraction, but no implementation is included. ^ The primary format is binary, but text and JSON formats are available. [8] [9]
This allows some implementations (e.g. JBoss [11]) to store HA1 rather than the cleartext password (however, see disadvantages of this approach) Client nonce was introduced in RFC 2617, which allows the client to prevent chosen-plaintext attacks, such as rainbow tables that could otherwise threaten digest authentication schemes
