1 RSA 加密算法属于非对称加密算法,第一步需要生成密钥对 publicstaticKeyPairinitKeyPair()throwsNoSuchAlgorithmException{KeyPairGeneratorkeyPairGenerator=KeyPairGenerator.getInstance(ALGORITHM);keyPairGenerator.initialize(KEY_SIZE);returnkeyPairGenerator.generateKeyPair();} 生成的java.security.KeyPair对象虽然已经...
This Java API allows you to easily and securely encrypt/decrypt important data using RSA and AES. Background I wanted to make an actual program in Java for the first time and when looking for many ways to use RSA in a Java program online, many were complicated and/or very outdated. So...
On the "server", an RSA key pair would be generated in Java as follows: KeyPairGenerator kpg = KeyPairGenerator.getInstance("RSA"); kpg.initialize(2048); KeyPair kp = kpg.genKeyPair(); Key publicKey = kp.getPublic(); Key privateKey = kp.getPrivate(); ...

RSA是一种常用的非对称加密算法。所以有时需要在不用编程语言中分别使用RSA的加密、解密。例如用Java做后台服务端,用C#开发桌面的客户端软件时。 由于.Net、Java 的RSA类库存在很多细节区别,尤其是它们支持的密钥格式不同。导致容易出现“我加密的数据对方不能解密,对方加密的数据我不能解密,但是自身是可以正常加密解...

Java使用RSA算法实现安全登录 使用RSA非对称加密算法对密码进行加密,能够保证传输数据的安全性。RSA公钥和私钥在服务器端生成,并且把私钥保存到服务器,把公钥的模数和指数传递给前端。前端根据模数和指数对密码进行加密,将密码密文传递给服务器。服务器根据私钥对密文进行解密,最后完成登录验证。本文主要介绍:“前端登录...
from the result in the program, you will see that the encrypted text and decrypted text are both wrong. This is because n is too small and needs to be much bigger in order for encryption and decryption to work properly Using small prime numbers is also a security concern as interceptors ...
RSA is a short form for Rivest, Shamir, and Adleman, are the people who first publicly described it in 1977.
