public key cryptography ppt

Digital signatures Digital signature (also known as public key digital signature, electronic seal) is a kind of common physical signature written on paper, but it uses the technology of public key cryptography to identify the digital information method. A set of digital sign

Nodejs's crypto module public key encryption and decryptionNodejs has the following 4 classes related to public key cryptography.1. Cipher: Used for encrypting data;2. Decipher: Used to decrypt data;3. Sign: Used to generate signatures;4. Verify: Used to verify the signature

The basic public key cryptography steps were presented by Whitfield Diffie and Martin Hellman in 1976. Mathematical concept: A "prime number" is a positive integer that can only be divisible by 1 and itself (except for the remainder of 0). The first 8 prime numbers are 1, 2, 3, 5, 7, 11, 13, 17 Any positive integer that is not a prime number can be converted

RSA public Key cryptography was developed in 1977 by Ron Rivest, Adi Shamirh and Lenadleman (Massachusetts Institute of America).The algorithm's name is also their three person initials, the RSA algorithm is based on a very simple number theory fact:Multiplying the two large primes is easy, but it is extremely difficult to factorization the product, so the produc

Common public key algorithms Here are three of the most common public-key algorithms: Rsa-is suitable for digital signatures and key exchange. Rivest-shamir-adleman (RSA) encryption algorithm is currently the most widely used public
