PHP RSA encryption, decryption, signature, verification Because the docking of third-party organizations using the Java version of the RSA encryption and decryption method, all just started on the internet to find a lot of PHP version of the RSA encryption, but most of the docking Java does not apply. The following PHP version is suitable for docking Java interf

and decryption speed is slow. The representation algorithm includes: RSA, ElGamal, Elliptic Curve Series algorithm. Generally applicable to the signature scene or key negotiation, not suitable for large amounts of data encryption and decryption. Combination mechanism The first is to negotiate a temporary symmetric encryption key (session

has a pair of public and private keys, then the process of encrypting decryption is as follows: Bob sends his public key to Alice. Alice encrypts her message with Bob's public key and sends it to Bob. Bob decrypts Alice's message with his private key. The above procedure ca

Conversion between RSA key C # format and Java format,Preface Recently, due to project requirements, the server is written by c # And the client is written by java. Communication Data is encrypted using RSA asymmetric encryption. However, the key formats generated by java and c # are different, so you need to convert t

ObjectiveRequires developers to use OpenSSL locally to generate private and public keysBecause the Mac comes with the OpenSSL tool, you don't have to download the OpenSSL tool like WindowsStep 1. Create a folder where the terminal enters the folderCd/users/tanqihong/desktop/rsa2. Terminal input OpenSSL open tool 3. Generate RSA private keyGenrsa-out RSA_PRIVATE_K

Topic Links:http://acm.hdu.edu.cn/showproblem.php?pid=1211Main topic:RSA is a powerful tool for encrypting data, and the RSA system is described as follows:Select two large prime numbers p, q, Calculate n = p * Q,F (n) = (p-1) * (q-1), select an integer e, make gcd (E,f (n)) = 1,E is the public key, calculation D makes d * e mod f (n) = 1 mod f (n), and D is the private
