Data Encryption Standard (DES)
|
Detailed explanation-1: -The DES algorithm uses a 56-bit key, and as expected from something with such a small key size, it is a symmetric key encryption algorithm-asymmetric keys are usually more than a thousand bits in length.
Detailed explanation-2: -The Data Encryption Standard (DES /ˌdiːˌiːˈɛs, dɛz/) is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure for modern applications, it has been highly influential in the advancement of cryptography.
Detailed explanation-3: -The two main uses of asymmetric-key algorithms are public-key encryption and digital signatures. Public-key encryption is a method where anyone can send an encrypted message within a trusted network of users.
Detailed explanation-4: -Ed25519 signing. X25519 key exchange. Ed448 signing. X448 key exchange. Elliptic curve cryptography. RSA. Diffie-Hellman key exchange. DSA. More items
