  2. Encryption - Wikipedia

    en.wikipedia.org/wiki/Encryption

    In cryptography, encryption (more specifically, encoding) is the process of transforming information in a way that, ideally, only authorized parties can decode.

  3. Cryptography - Wikipedia

    en.wikipedia.org/wiki/Cryptography

    Symmetric-key cryptography refers to encryption methods in which both the sender and receiver share the same key (or, less commonly, in which their keys are different, but related in an easily computable way). This was the only kind of encryption publicly known until June 1976. [34]

  4. RSA (cryptosystem) - Wikipedia

    en.wikipedia.org/wiki/RSA_(cryptosystem)

    RSA (Rivest–Shamir–Adleman) is a public-key cryptosystem, one of the oldest widely used for secure data transmission.The initialism "RSA" comes from the surnames of Ron Rivest, Adi Shamir and Leonard Adleman, who publicly described the algorithm in 1977.

  5. Homomorphic encryption - Wikipedia

    en.wikipedia.org/wiki/Homomorphic_encryption

    Homomorphic encryption is a form of encryption that allows computations to be performed on encrypted data without first having to decrypt it. The resulting computations are left in an encrypted form which, when decrypted, result in an output that is identical to that produced had the operations been performed on the unencrypted data.

  6. Encryption software - Wikipedia

    en.wikipedia.org/wiki/Encryption_software

    Software encryption uses a cipher to obscure the content into ciphertext. One way to classify this type of software is the type of cipher used. Ciphers can be divided into two categories: public key ciphers (also known as asymmetric ciphers), and symmetric key ciphers. [4] Encryption software can be based on either public key or symmetric key ...

  7. History of cryptography - Wikipedia

    en.wikipedia.org/wiki/History_of_cryptography

    Encryption in modern times is achieved by using algorithms that have a key to encrypt and decrypt information. These keys convert the messages and data into "digital gibberish" through encryption and then return them to the original form through decryption. In general, the longer the key is, the more difficult it is to crack the code.

  8. Public-key cryptography - Wikipedia

    en.wikipedia.org/wiki/Public-key_cryptography

    In a public-key encryption system, anyone with a public key can encrypt a message, yielding a ciphertext, but only those who know the corresponding private key can decrypt the ciphertext to obtain the original message.

  9. Cryptography standards - Wikipedia

    en.wikipedia.org/wiki/Cryptography_standards

    FIPS PUB 185 Escrowed Encryption Standard (EES) 1994, a key escrow system that provides for decryption of telecommunications when lawfully authorized. FIPS PUB 186-2 Digital Signature Standard 2000; FIPS PUB 190 Guideline for the Use of Advanced Authentication Technology Alternatives 1994
