End-to-end encryption (E2EE) is a method of implementing a secure communication system where only communicating users can participate. No one else, including...

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

Diffie–Hellman key exchange, public-key key encapsulation, and public-key encryption. Public key algorithms are fundamental security primitives in modern cryptosystems...

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...

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

Structured encryption (STE) is a form of encryption that encrypts a data structure so that it can be privately queried. Structured encryption can be used...

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

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

Encryption software is software that uses cryptography to prevent unauthorized access to digital information. Cryptography is used to protect digital information...

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...

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

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...

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

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

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

(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...

Disk encryption is a special case of data at rest protection when the storage medium is a sector-addressable device (e.g., a hard disk). This article presents...

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...

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...

Identity-based encryption (IBE), is an important primitive of identity-based cryptography. As such it is a type of public-key encryption in which the public...
