FAQ
Frequently Asked Questions
In cryptography, 'plaintext' is the standard single-word term. 'Plain text' (two words) more commonly refers to text without formatting (e.g., .txt file). However, in general IT, the terms are sometimes used interchangeably.
In standard usage, it is a noun or adjective. Using it as a verb (e.g., 'to plaintext data') is non-standard jargon but may be encountered in very informal technical discussions.
No. In modern usage, 'plaintext' can refer to any unencrypted data, including binary data, numbers, or files, not just human-readable text.
They are largely synonymous. 'Cleartext' is sometimes used to emphasise that the data is not only unencrypted but also immediately understandable (e.g., not compressed or encoded). 'Plaintext' is the more common term in formal cryptography.
Unencrypted, ordinary text or data that is readable without any special processing or decryption.

Mnemonic
Think of a 'plain' postcard anyone can read, versus a 'ciphertext' which is like a secret code. Plaintext = plainly readable text.
Conceptual Metaphor
TEXT IS AN OBJECT (that can be transformed); SECRECY IS COVERING/CONCEALING (plaintext is uncovered, ciphertext is covered).
