Plaintext

Replacing high frequency ciphertext symbols with high frequency plaintext letters does not reveal chunks of plaintext because of the transposition.

Synchronous stream ciphers In a synchronous stream cipher a stream of pseudo-random digits is generated independently of the plaintext and ciphertext messages, and then combined with the plaintext (to encrypt) or the ciphertext (to decrypt).

Thus, the a priori probability of a plaintext message M is the same as the a posteriori probability of a plaintext message M given the corresponding ciphertext.

You don't seem that the entire industry is killing you owning your hardware, aka they are killing plaintext microcontrollers.

Both will correspond to an individual’s real-life identity, but will exclude any plaintext information.

When you enter a password into a website, it is usually not stored as you entered it in plaintext, or at least we hope that is the case.

More than 440 million individual data entries were found sitting in plaintext in a cloud database.

During the process, he found that the operating system was storing portions of user emails in plaintext, even when they were supposed to be encrypted.

In 2018, Twitter confirmed that it stored passwords in plaintext, revealed a phone number leak bug despite having the knowledge about it for two years, and also admitted a location data leak in May.

Plaintext protocols that make usage of a straightforward procedure to location information are utilized by Web-businesses.

A CHK is a SHA-256 hash of a document (after encryption, which itself depends on the hash of the plaintext) and thus a node can check that the document returned is correct by hashing it and checking the digest against the key.

A separate notion was the use of a one-time pad of letters to encode plaintext directly as in the example below.

A set of reverse rounds are applied to transform ciphertext back into the original plaintext using the same encryption key.

A similar reduction in data complexity can be obtained in a chosen-plaintext variant of linear cryptanalysis (Knudsen and Mathiassen, 2000).

A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream ( keystream ).

As with any stream cipher, these can be used for encryption by combining it with the plaintext using bit-wise exclusive-or ; decryption is performed the same way (since exclusive-or with given data is an involution ).

Badly chosen routes will leave excessive chunks of plaintext, or text simply reversed, and this will give cryptanalysts a clue as to the routes.

Because the key material must be transported from one endpoint to another, and persist until the message is sent or received, it can be more vulnerable to forensic recovery than the transient plaintext it protects (see data remanence ).

Because these schemes pad the plaintext m with some number of additional bits, the size of the un-padded message M must be somewhat smaller.
