In cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher. [1] . Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it.
This definition explains ciphertext, including what it is and how it's different from plaintext and cleartext. Learn about the types of ciphers used, ciphertext attacks and examples of ciphertext.

Jan 14, 2023 · Ciphertext is an essential tool for protecting information from being accessed by unauthorized individuals. To read ciphertext, one must have the proper key or algorithm. There are several different cipher types, but the most common ones used today are the Substitution and Transposition ciphers.
- A ciphertext-only attack is when an attacker can access ciphertext but not the corresponding plain text or key. Even though the attacker does not h...
- A cipher is a mathematical function used to encrypt and decrypt data. ciphertext is the data that has been encrypted using a cipher.
- An example of a symmetric key cipher is the AES (Advanced Encryption Standard) cipher. This type of cipher uses the same key for both encryption an...
- An example of a public key cipher is the RSA (Rivest-Shamir-Adleman) cipher. This type of cipher uses different keys for encryption and decryption.
Feb 24, 2023 · Share. Last update on August 16, 2023 Published on February 24, 2023. Ciphertext is unreadable, encrypted data that can only be read if you know the key. Learn all about ciphertext and how it ensures your data privacy by securing computers and online communications, including encrypted email.
Algorithms transform plaintext into ciphertext, and vice versa, to convert ciphertext back into plaintext. These processes are known as encryption and decryption. Ciphertext, represents a cryptographic approach in which an algorithm utilizes substitutions instead of original plaintext elements.
Apr 18, 2024 · Ciphertext refers to data that is encrypted and unreadable. The only way to read encrypted data is by decrypting it using an encryption key. Since ciphertext can’t be read without providing the encryption key, it’s the best way to protect your sensitive data from prying eyes and unauthorized access.
