  Plaintext - Wikipedia, the free encyclopedia
In cryptography, plaintext is information used as input to an encryption algorithm; the output is termed ciphertext.
Plaintext is typically human readable, either directly or with some commonly available device, such as a Compact Disk player.
Plaintext is vulnerable in use and in storage, whether in electronic or paper format.

The plaintext could be, for example, a diplomatic message, a bank transaction, an email, a diary and so forth — any information that someone might want to prevent others from reading.
If plaintext is kept in a computer file, the disk (or perhaps the entire computer) and its components must be secure.
Padding is often used, and it is common to run all messages being sent through a data compression algorithm prior to submitting the result (the actual plaintext for encryption to a cryptosystem).

 Plaintext — CLC Plone   (Site not responding. Last check: 2007-10-26)
ASCII is plaintext, but since ASCII is defined by encoding standards, this makes the "unformattedness" of plaintext a function of the formats and protocols regulating its appearance.
Plaintext is also a term from cryptography, where it refers to the input into a crypto system, or the message to be encoded (also referred to as "clear text").
Plaintext is a strategic resource in the military intelligence world of cryptography.

 Chosen plaintext attack - Wikipedia, the free encyclopedia
A chosen plaintext attack is any form of cryptanalysis which presumes that the attacker has the capability to choose arbitrary plaintexts to be encrypted and obtain the corresponding ciphertexts.
This appears, at first glance, to be an unrealistic model; it would certainly be unlikely that an attacker could persuade a human cryptographer to encrypt large amounts of plaintexts of the attacker's choosing.
Conventional symmetric ciphers, in which the same key is used to encrypt and decrypt a text, are often vulnerable to this type of attack, for example, differential cryptanalysis of block ciphers.

 Cryptology
To decrypt the plaintext letter is found at the head of the column determined by the intersection of the diagonal containing the cipher letter and the row containing the key letter.
While the encryption of any particular plaintext with a block cipher will result in the same ciphertext when the same key is used; with a stream cipher, the transformation of the smaller plaintext units will vary, depending on when they are encountered during the encryption process.
If the plaintext segment is guessed it is unlikely that its exact position is known however a message is generally short enough for a cryptanalyst to try all possible positions in parallel.

 Plaintext   (Site not responding. Last check: 2007-10-26)
During encryption, if the plaintext is transformed by a cipher algorithm, the result will be a ciphertext.
Since dumpster diving is widely possible, and reconstruction of even shredded sheets possible for those sufficiently committed to their recovery, discarded printed plaintexts must be thoroughly crosscut shredded, burned, or otherwise made un-diveable.
Second, possession of any plaintext whatsoever, whether it is itself meaningful (and perhaps sensitive) or merely some administrivia, makes several cryptanalytic attacks either possible or easier.

This hatred of plaintext is also evident in Hotmail, Microsoft's Trojan horse to Passport.
One possible reason is it comes from the PC-world where having a printer was all important, and don't understand that desktop publishing functions like bold, italic, and underline make no sense in the networked world, where data is rarely printed out.
Plaintext can be created by anything and read by anything.

 Amount of Plaintext Known to Attackers
The more plaintext that is known to attackers, the greater the potential that an attacker can discover the encryption key used to produce ciphertext.
For a chosen plaintext attack, an attacker chooses plaintext and submits it to be encrypted.
All public key cryptosystems are vulnerable to chosen plaintext attacks and, thus, use a variety of techniques to protect against these attacks.

 Known Plaintext Attack
In this paper we describe a known plaintext attack on the PKZIP stream cipher which takes a few hours on a personal computer and requires about 13--40 (compressed) known plaintext bytes, or the first 30--200 uncompressed bytes, when the file is compressed.
The known plaintext bytes are the inputs of the update_keys function, and the derived key3's are the outputs.
In this case, 13 known plaintext bytes are required for the whole attack, and the complexity of analysis is 2^{38}.

 Editor Plaintext Embedding
In the NS 6.0 codebase, the editor is always an html editor, and plaintext editing is a special case of html.
The plaintext editor is intended to be a lightweight replacement for native text fields and text areas.
The plaintext editor is explicitly not intended to be a "rich-text editor" which allows changes such as bold, italic, etc. While there is definitely a need for a rich-text editing interface (distinct from more elaborate editing functionality such as table editing), most clients requesting a plaintext editor do not need this functionality.

The PLAINTEXT element defined a separated multi-line set of text to be rendered as it exists in the source document with the same line breaks.
Only the PLAINTEXT ending element is recognized as an element inside of PLAINTEXT content, all else is treated as character data.
Comments in RFC 1866 state that PLAINTEXT has no ending element and all characters after the start element are data.

 Monoalphabetic Substitution
Keep in mind that the definition of a monoalphabetic substitution allows for the possibility that two distinct plaintext letters are replaced by the same cyphertext letter.
To this end, we will use the convention that plaintext letters are always in uppercase and cyphertext letters are always in lowercase.
To break a monoalphabetic substitution using a known plaintext attack, we can take advantage of the fact that any pair of letters in the original plaintext message is replaced by a pair of letters with the same pattern.

 Known-Plaintext and Compression
But, in practice, it is very difficult to prevent some amount of plaintext from escaping, because the information in that plaintext may not have any worth, and so will not be protected.
The job of the plaintext is to represent whatever data is being communicated.
If we communicate in distinct messages, and if the "plaintext" includes a length field, that "length" had better be modulo or block size, or we will be describing in plaintext a size the opponents can see as ciphertext.

 Definition of Ciphertext-only attack
In cryptography, a ciphertext-only attack is a form of cryptanalysis where the attacker is assumed to have access only to a set of ciphertexts.
The attack is completely successful if the corresponding plaintexts can be deduced, or even better, the key.
All that is needed is some way to distinguish valid plaintext from random noise, never a problem for natural languages.

When plaintext passwords are disabled, the IMAP server will advertise the LOGINDISABLED capability and the POP3 server will not advertise the USER capability.
Plaintext passwords will always be enabled in SSL sessions; the IMAP server will not advertise the LOGINDISABLED capability and the POP3 server will advertise the USER capability.
If the client does a successful start-TLS in a non-SSL session, plaintext passwords will be enabled, and a new CAPABILITY or CAPA command (which is required after start-TLS) will show the effect as in SSL sessions.

 How PGP works
The method of disguising plaintext in such a way as to hide its substance is called encryption.
PGP uses a cryptographically strong hash function on the plaintext the user is signing.
PGP can encrypt the plaintext or not; signing plaintext is useful if some of the recipients are not interested in or capable of verifying the signature.

This number depends both on the characteristics of the plaintext and the key length of the encryption algorithm.
For other plaintexts it will be more or less, but not that much more or less.) For DES, the unicity distance is 8.2 bytes.
If the plaintext is a random key, the redundancy is zero and the unicity distance reaches infinity: it is impossible to recognize the correct plaintext from an incorrect plaintext.

Each plaintext letter selects an entry in the substitution table (for that cipher), and the contents of that entry becomes the ciphertext letter.

One solution to this problem is, through the use of cryptography, to prevent intruders from being able to use the information that they capture.
Encryption is the process of translating information from its original form (called plaintext) into an encoded, incomprehensible form (called ciphertext).
Decryption refers to the process of taking ciphertext and translating it back into plaintext.

Since the idea of the PUA is a « free-for-all, » any type of character belonging to any script may be included in the PUA.
2) Since the nature of PUA characters which can be serviced by fonts can vary from font to font, identifying PUA characters on a plaintext level may be moot, a rich text format level being required to identify fonts in text.
