Authenticated Encryption (AE) is an encryption scheme which simultaneously assures the data confidentiality (also known as privacy: the encrypted message...

Homomorphic encryption is a form of encryption that allows computations to be performed on encrypted data without first having to decrypt it. The resulting...

In cryptography, the ElGamal encryption system is an asymmetric key encryption algorithm for public-key cryptography which is based on the Diffie–Hellman...

Cryptography prior to the modern age was effectively synonymous with encryption, converting readable information (plaintext) to unintelligible nonsense...

End-to-end encryption (E2EE) is a private communication system in which only communicating users can participate. As such, no one else, including the communication...

That system was declassified in 1997. In a public-key cryptosystem, the encryption key is public and distinct from the decryption key, which is kept secret...

cryptography, null encryption (or selecting null cipher or NONE cipher) is choosing not to use encryption in a system where various encryption options are offered...

Link encryption is an approach to communications security that encrypts and decrypts all network traffic at each network routing point (e.g. network switch...

itself is only suitable for the secure cryptographic transformation (encryption or decryption) of one fixed-length group of bits called a block. A mode...

In cryptography and steganography, plausibly deniable encryption describes encryption techniques where the existence of an encrypted file or message is...

volume encryption feature included with Microsoft Windows versions starting with Windows Vista. It is designed to protect data by providing encryption for...

Disk encryption is a technology which protects information by converting it into code that cannot be deciphered easily by unauthorized people or processes...

Pretty Good Privacy (PGP) is an encryption program that provides cryptographic privacy and authentication for data communication. PGP is used for signing...

The Data Encryption Standard (DES /ˌdiːˌiːˈɛs, dɛz/) is a symmetric-key algorithm for the encryption of digital data. Although its short key length of...

as cascade encryption, cascade ciphering, multiple encryption, and superencipherment. Superencryption refers to the outer-level encryption of a multiple...

Probabilistic encryption is the use of randomness in an encryption algorithm, so that when encrypting the same message several times it will, in general...

Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in...

Dynamic Encryption is a cryptographic principle that enables two parties to change the encryption algorithm for every transaction. The principle of Dynamic...

Email encryption is encryption of email messages to protect the content from being read by entities other than the intended recipients. Email encryption may...

In cryptography, Triple DES (3DES or TDES), officially the Triple Data Encryption Algorithm (TDEA or Triple DEA), is a symmetric-key block cipher, which...

Database encryption can generally be defined as a process that uses an algorithm to transform data stored in a database into "cipher text" that is incomprehensible...

A deterministic encryption scheme (as opposed to a probabilistic encryption scheme) is a cryptosystem which always produces the same ciphertext for a...

Honey encryption is a type of data encryption that "produces a ciphertext, which, when decrypted with an incorrect key as guessed by the attacker, presents...

Functional encryption (FE) is a generalization of public-key encryption in which possessing a secret key allows one to learn a function of what the ciphertext...

(HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP). It uses encryption for secure communication over a computer network, and is widely used on...
