Finally, the Euclid algorithm is used to compute the decryption key D to meetE * d = 1 (mod (p-1) * (q-1))where N and D are also coprime. The number e and n are public keys, and D is the private key. Two primes p and Q no longer needed, should be discar

encrypted. When the encryption algorithm is used in this mode, in addition to the key, you also need to negotiate an initialization vector (iv), this IV has no practical significance, but only in the first calculation of the need to use it. With this model, security can be increased.A typical example of a block cipher is Des,rc5,idea.A typical example of a sequence cipher is RC4.

RSA algorithm is the first algorithm that can be used in both encryption and digital signature, and it is easy to understand and operate. RSA is the most widely studied public-key algorithm, from the proposed to now nearly 20 years, experienced a variety of attacks, gradually accepted by people, generally considered to be one of the best public

Introduction rsa cryptosystem is a public key cryptosystem which is proposed earlier. In 1978, Rivest,shamir and Adleman of the Massachusetts Institute of MIT (MIT) presented an asymmetric (public key) cryptosystem based on number theory, called the RSA Cryptosystem, in a paper entitled "Methods for obtaining digital

The communication between networks is realized by means of transmitting messages, and in the process of transmitting these messages, it is very important to encrypt the message in order to protect the content from being stolen and modified.
