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 gener
Asymmetric encryption has been rated as the encryption standard, mainly includes (public key encryption private key decryption, or private key encryption public key decryption) This article mainly explains how to generate the public and private keys and string encryption and string decryption in JavaIf you need code co

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. The header file is placed in the Include folder and the CPP is placed in the SRC di

You can use Keypairgenerator to generate a public/private key pair in your code. Generating a key is a CPU-consuming job.

//Generate key pair
keypairgenerator KeyGen = Keypairgenerator.getinstance ("RSA");
Keygen.initialize (1024);

The RSA algorithm is the first algorithm that can be used for both data encryption and digital signature. It is easy to understand and operate, and is also popular. Its security is based on the difficulty of big integer factorization, while the big integer factorization is a famous mathematical problem. So far, there is no effective solution, therefore, the security of the RSA algorithm can be ensured.

The RSA algorithm is the first algorithm that can be used for both encryption and digital signature, and it is easy to understand and manipulate. RSA is the most widely researched 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
About RSA encryption and decryption problem, nothing to get a bit, first the main process to save, for Exchange or later use.First make sure that you have the OpenSSL installed on your PC, and that your Mac system will install automatically after installation! How to install?? ..... Please Baidu ...The installation commands are as follows:sudo apt-get install OpenSSLCreate a folder anywhere in your location to save your public
For the issue of RSA encryption and decryption, just get it done. First, save the main process for communication or future use. First, make sure that OpenSSL is installed on your computer. Generally, it is automatically installed on Mac! How to install it ??..... Please Baidu ...... The installation command is as follows: Sudo apt-Get install OpenSSL Create a folder anywhere you want to save your public key
