jAvA 中的CiphEr类RSA方式能不能用私钥加密公钥解...

KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA"); keyGen.initialize(1024); KeyPair key = keyGen.generateKeyPair(); Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding"); //把第二个参数改为 key.getPrivate() cip...

可以设定RSA,1024bit或2048bit两种

下面是RSA加密代码。 /** * RSA算法,实现数据的加密解密。 * @author ShaoJiang * */ public class RSAUtil { private static Cipher cipher; static{ try { cipher = Cipher.getInstance("RSA"); } catch (NoSuchAlgorithmException e) { e.pr...

using System;using System.Security.Cryptography;using System.Text;public static void Main(String[] args){var strPriKey = ""; // 你的私钥的Base64格式字符串(不需要公钥,私钥已包含公钥信息)using (var rsa = Init(strPriKey)){// 加...

有尝试过,约定字符集编码了吗? 我也遇到了,猜测可能和字符集编码有关。

有点区别,java中默认填充方式是RSA/ECB/PKCS1Padding,Cipher.getInstance("RSA/ECB/PKCS1Padding");android不是 java Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding"); android Cipher cipher = Cipher.getInstance("RSA/ECB/NoP...

public String encryptStringWithRSA(RSAPublicKey publicKey, String str) { String key; try { key = encode(publicKey.getEncoded()); byte[] keyBytes = decode(key); X509EncodedKeySpec x509KeySpec = new X509EncodedKeySpec(keyBytes); ...
