asymmetric encryption example

encrypt, while decryption requires another key. For example, you ask the bank for the public key, the bank sends you the public key, you encrypt the message using the public key, then only the holder of the private key-the bank can decrypt your message. Unlike symmetric encryption, the bank does not need to send the private key over the network, so security is greatly improved.The most commonly used

1.Encryption Algorithm Daquan:Rsa:RSA is made of the initial letters of the surnames of Ron Rivest, Adi Shamir, and Leonard Adleman, who first publicly desc Ribed the algorithm in 1977.Http://www.emc.com/corporate/about-rsa/index.htmHttps://en.wikipedia.org/wiki/RSA_%28cryptosystem%29DSA: Digitally Signature algorithm digital Signature AlgorithmECDSA: Elliptic Curve digital Signature algorithm Elliptic curve Signature algorithmDSS: Digital Signature S

Des:Digital Encryption Standard. Obsolete Standard.Single key algorithm is the sender of the information using key A for data encryption, the receiver of the information uses the same key a for data decryption. The single key algorithm is a symmetric algorithm.The algorithm is good at adding/solving speed, the key volume is short, symmetric encryption is used Dsa

Http://www.cnblogs.com/1-2-3/archive/2007/09/17/colloquialism-digital-certificate-part1.htmlSummaryThis series is easy to read, so you can understand the basic principles of digital signatures and how to apply them (even if you are an enterprise boss who is not computer savvy, you can read this article). Then we step into the technical details, and finally will give a B/s information system using the digital signature demo.Because the digital signature is based on

One, asymmetric encryptionAsymmetric encryption has a set of key pairs, one is public, anyone can obtain, called the public key;One is self-preservation and strictly confidential, called the private key.The rules are as follows:by someone A the public key encrypted message, only by the A the private key is decrypted;by A The private key encrypts the message, only by the A decryption of the public key. sende

Asymmetric Cryptography Concepts 1, the main difference with the symmetric encryption algorithm is that encryption and decryption of the key is not the same, a public (public key), a secret (private key). This paper mainly solves the problem of key distribution management of symmetric encryption algorithm, and improve

Ixi In actual applications, symmetric encryption is not enough. In more cases, symmetric encryption and asymmetric encryption are used in combination. asymmetric encryption (public key encrypt
