In the project you need to add a registration function, think of using RSA Asymmetric encryption method. Third-party libraries such as OpenSSL were compared, and Cryptopp was used.1. source File CollationYou can get the source files of the library in http://www.cryptopp.com/, and then archive the files again after extracting them.

In general, the current SaaS service provides the current SDK or API docking service that involves an authentication and data encryption issue. It is generally common practice to configure the use of asymmetric encryption to solve this problem, you hold the public key of the SaaS company, the SaaS company holds your public key, you can do encryption and signature verification.Let's look at two ways to generate key pair under Linux or Mac:Using OpenSSL to generate a 2048bit-length key pair, we fi
Php rsa encryption and decryption methods and development interfaces, rsa encryption and decryption
Network security is very important, especially to ensure data security. Many programmers who write interfaces directly transmit plaintext data. In my opinion, this is not professional. I advocate that all data through interfaces should be encrypted and decrypted before use.

Brief introductionRSA Asymmetric encryption has a very strong security, HTTPS SSL encryption is the use of this method of HTTPS requests encrypted transmission. Because the RSA algorithm involves private key and public key respectively for encryption and decryption, it is called asymmetric encryption. Private key and public key have interoperability, that is encrypted with private key can be decrypted with public key, with public key encryption can be

Asp can decrypt the ciphertext encrypted by using the built-in RSA method with the RSA that comes with PHP. this is now the case. here (Company A) there is something that was previously outsourced to Company B, ASP is used on the other side, and PHP is used on the company side. now B needs to be used. Now A generates the private key and public key (refer to blog. csdn. netclh604articledetails20224735), prov
