云享通.Net Core针对常用加解密常规操作库

云享通.Net Core针对常用加解密常规操作库，如：RSA,PKCS1,PKCS8,SHA1WITHRSA,MD5,SM2,SM3,SM4,SHA256,HMAC-SHA256，同时支持RSA的私钥格式转换PrivateKeyPkcs1ToPkcs8和PrivateKeyPkcs8ToPkcs1

典型示例

国密2加解密及签名验签示例

// 生成密钥对
CryptoSM2.GenerateKey(out var publicKey, out var privateKey);

Console.WriteLine($"Public Key: {publicKey}");
Console.WriteLine($"Private Key: {privateKey}");

// 测试加密：Base64与Hex
string message = "Hello, SM2! 你好";
string encryptedBase64 = CryptoSM2.EncryptStringToBase64(message, publicKey, true);  // true表示返回Base64
string encryptedHex = CryptoSM2.EncryptToHex(Encoding.UTF8.GetBytes(message), publicKey);

Console.WriteLine($"Encrypted Base64: {encryptedBase64}");
Console.WriteLine($"Encrypted Hex: {encryptedHex}");

// 测试解密
string decrypted = CryptoSM2.DecryptFromBase64(encryptedBase64, privateKey);
Console.WriteLine($"Decrypted: {decrypted}");

// 测试签名
string signature = CryptoSM2.Sign(message, privateKey);
Console.WriteLine($"Signature: {signature}");

// 测试验证签名
bool isVerified = CryptoSM2.VerifySign(message, signature, publicKey);
Console.WriteLine($"Signature Verified: {isVerified}");

// 加密解密的完整流程
Console.WriteLine("\n--- Complete Encryption/Decryption Test ---");
string originalMessage = "Encrypt and Decrypt with SM2";
string encryptedMessage = CryptoSM2.EncryptStringToBase64(originalMessage, publicKey, true);
string decryptedMessage = CryptoSM2.DecryptFromBase64(encryptedMessage, privateKey);

Console.WriteLine($"Original Message: {originalMessage}");
Console.WriteLine($"Encrypted Message (Base64): {encryptedMessage}");
Console.WriteLine($"Decrypted Message: {decryptedMessage}");

// 签名与验证的完整流程
Console.WriteLine("\n--- Complete Signing/Verification Test ---");
string originalMessageForSign = "SM2 Signing Example";
string generatedSignature = CryptoSM2.Sign(originalMessageForSign, privateKey);
bool verificationResult = CryptoSM2.VerifySign(originalMessageForSign, generatedSignature, publicKey);

Console.WriteLine($"Original Message: {originalMessageForSign}");
Console.WriteLine($"Generated Signature: {generatedSignature}");
Console.WriteLine($"Signature Verification Result: {verificationResult}");

国密3加密示例

string text = "你好, SM3!";
string charset = "utf-8";

// 加密为字节数组
byte[] hashBytes = CryptoSM3.Encrypt(text, charset);
Console.WriteLine($"Encrypt: {BitConverter.ToString(hashBytes).Replace("-", "")}");

// 加密为 HEX 字符串
string hashHex = CryptoSM3.EncryptToHex(text, charset);
Console.WriteLine($"Encrypt To Hex: {hashHex}");

// 加密为 Base64 字符串
string hashBase64 = CryptoSM3.EncryptToBase64(text, charset);
Console.WriteLine($"Encrypt To Base64: {hashBase64}");

// 测试不同字符集
string textGBK = "你好, SM3! (GBK)";
string charsetGBK = "gbk";
string hashHexGBK = CryptoSM3.EncryptToHex(textGBK, charsetGBK);
Console.WriteLine($"Encrypt To Hex (GBK): {hashHexGBK}");

string hashBase64GBK = CryptoSM3.EncryptToBase64(textGBK, charsetGBK);
Console.WriteLine($"Encrypt To Base64 (GBK): {hashBase64GBK}");

// 测试空字符串
string emptyText = string.Empty;
string emptyHex = CryptoSM3.EncryptToHex(emptyText);
Console.WriteLine($"Encrypt To Hex (Empty): {emptyHex}");

string emptyBase64 = CryptoSM3.EncryptToBase64(emptyText);
Console.WriteLine($"Encrypt To Base64 (Empty): {emptyBase64}");

国密4加/解密示例

string key = "1234567890abcdef";
string iv = "abcdef1234567890";
string text = "你好, SM4!";

// ECB 模式
string ecbHex = CryptoSM4.EncryptECBToHex(key, text);
string ecbBase64 = CryptoSM4.EncryptECBToBase64(key, text);
Console.WriteLine($"ECB Hex: {ecbHex}");
Console.WriteLine($"ECB Base64: {ecbBase64}");
Console.WriteLine($"ECB Decrypt Hex: {CryptoSM4.DecryptECBFromHex(key, ecbHex)}");
Console.WriteLine($"ECB Decrypt Base64: {CryptoSM4.DecryptECBFromBase64(key, ecbBase64)}");

// CBC 模式
string cbcHex = CryptoSM4.EncryptCBCToHex(key, iv, text);
string cbcBase64 = CryptoSM4.EncryptCBCToBase64(key, iv, text);
Console.WriteLine($"CBC Hex: {cbcHex}");
Console.WriteLine($"CBC Base64: {cbcBase64}");
Console.WriteLine($"CBC Decrypt Hex: {CryptoSM4.DecryptCBCFromHex(key, iv, cbcHex)}");
Console.WriteLine($"CBC Decrypt Base64: {CryptoSM4.DecryptCBCFromBase64(key, iv, cbcBase64)}");

RSA加密及验签

// 生成RSA密钥对
var rsa = new CryptoRSA(2048, CryptoRSA_PKCSType.PKCS8, true);
Console.WriteLine($"Public Key:\n{rsa.PublicKey}");
Console.WriteLine($"Private Key:\n{rsa.PrivateKey}");

// 从私钥中提取公钥
string extractedPublicKey = CryptoRSA.GetPublicKeyFromPrivateKey(rsa.PrivateKey, CryptoRSA_PKCSType.PKCS8);
Console.WriteLine($"Extracted Public Key:\n{extractedPublicKey}");

// 私钥格式转换：PKCS8转PKCS1
string pkcs1PrivateKey = CryptoRSA.PrivateKeyPkcs8ToPkcs1(rsa.PrivateKey, true);
Console.WriteLine($"PKCS8 to PKCS1 (PEM):\n{pkcs1PrivateKey}");

// 私钥格式转换：PKCS1转PKCS8
string pkcs8PrivateKey = CryptoRSA.PrivateKeyPkcs1ToPkcs8(pkcs1PrivateKey, true);
Console.WriteLine($"PKCS1 to PKCS8 (PEM):\n{pkcs8PrivateKey}");

// 数据签名与验签
string data = "Hello, RSA!";
string signSHA1 = CryptoRSA.SHA1WithRSASign(data, rsa.PrivateKey);
Console.WriteLine($"SHA1 Sign:\n{signSHA1}");

bool isValidSHA1 = CryptoRSA.SHA1WithRSAValid(data, rsa.PublicKey, signSHA1);
Console.WriteLine($"SHA1 Signature Valid: {isValidSHA1}");

string signSHA256 = CryptoRSA.SHA256WithRSASign(data, rsa.PrivateKey);
Console.WriteLine($"SHA256 Sign:\n{signSHA256}");

bool isValidSHA256 = CryptoRSA.SHA256WithRSAValid(data, rsa.PublicKey, signSHA256);
Console.WriteLine($"SHA256 Signature Valid: {isValidSHA256}");
