AzrngCommon.Security
AzrngCommon.Security 是一个常用加密工具库,覆盖国际通用算法与国密算法,提供统一的编码输入输出(Base64/Hex)。
- 对称加密:AES、AES-GCM、DES、3DES、SM4
- 非对称加密:RSA、SM2
- 哈希与消息认证:MD5、SHA1/SHA256/SHA512、SM3、HMAC
- 目标框架:
netstandard2.1; net6.0; net7.0; net8.0; net9.0; net10.0
安装
Install-Package AzrngCommon.Security
dotnet add package AzrngCommon.Security
快速开始
1) AES-GCM(推荐,具备完整性校验)
using Common.Security;
using Common.Security.Enums;
var plain = "hello aes-gcm";
var (key, _) = AesHelper.ExportSecretAndIv(256, OutType.Base64);
// 推荐使用命名参数,明确调用 GCM 重载
var cipher = AesGcmHelper.Encrypt(
plainText: plain,
secretKey: key,
secretType: SecretType.Base64,
outType: OutType.Base64);
var restored = AesGcmHelper.Decrypt(
cipherCombined: cipher,
secretKey: key,
secretType: SecretType.Base64,
cipherTextType: OutType.Base64);
2) AES-CBC(兼容场景)
using Common.Security;
using Common.Security.Enums;
var plain = "hello aes-cbc";
var (key, iv) = AesHelper.ExportSecretAndIv(256, OutType.Base64);
// 安全默认包装:CBC + PKCS7
var cipher = AesHelper.EncryptCbcPkcs7(plain, key, iv);
var restored = AesHelper.DecryptCbcPkcs7(cipher, key, iv);
3) RSA(推荐 OAEP-SHA256 + PSS)
using Common.Security;
using Common.Security.Enums;
using System.Security.Cryptography;
var source = "hello rsa";
var (publicKey, privateKey) = RsaHelper.ExportBase64RsaKey();
// 加解密(推荐 OAEP-SHA256)
var cipher = RsaHelper.EncryptOaepSha256(source, publicKey, keyType: RSAKeyType.PEM);
var restored = RsaHelper.DecryptOaepSha256(cipher, privateKey, keyType: RSAKeyType.PEM, privateKeyFormat: RsaKeyFormat.PKCS8);
// 签名验签(推荐 PSS)
var sign = RsaHelper.SignDataPss(source, privateKey, HashAlgorithmName.SHA256, privateKeyType: OutType.Base64);
var ok = RsaHelper.VerifyDataPss(source, sign, publicKey, HashAlgorithmName.SHA256, publicKeyType: OutType.Base64);
详细用法
哈希与 HMAC
using Common.Security;
using Common.Security.Enums;
var md5 = Md5Helper.GetMd5Hash("abc");
var md5_16 = Md5Helper.GetMd5Hash("abc", is16: true);
var fileMd5 = Md5Helper.GetFileMd5Hash("appsettings.json");
var sha256 = ShaHelper.GetSha256Hash("abc");
var sha512 = ShaHelper.GetSha512Hash("abc");
var fileSha256 = ShaHelper.GetFileSha256Hash("appsettings.json", OutType.Hex);
var fileSha512 = ShaHelper.GetFileSha512Hash("appsettings.json", OutType.Hex);
var hmac = ShaHelper.GetHmacSha256Hash("payload", "secret", OutType.Base64);
var verified = ShaHelper.VerifyHmacSha256Hash("payload", "secret", hmac, OutType.Base64);
AES-GCM 分段输出
适合将 Cipher/Nonce/Tag 分开存储或跨系统传输。
using Common.Security;
using Common.Security.Enums;
var (key, _) = AesHelper.ExportSecretAndIv(256, OutType.Base64);
var (cipher, nonce, tag) = AesGcmHelper.EncryptToParts("hello", key, outType: OutType.Base64);
var plain = AesGcmHelper.DecryptFromParts(cipher, nonce, tag, key, cipherTextType: OutType.Base64);
RSA 兼容接口(历史系统)
using Common.Security;
using Common.Security.Enums;
using System.Security.Cryptography;
var (pub, pri) = RsaHelper.ExportPemRsaKey(RsaKeyFormat.PKCS1);
// 兼容模式:PKCS#1 v1.5
var cipher = RsaHelper.Encrypt("legacy-data", pub);
var plain = RsaHelper.Decrypt(cipher, pri, privateKeyFormat: RsaKeyFormat.PKCS1);
var sign = RsaHelper.SignData("legacy-data", pri, HashAlgorithmName.SHA256);
var ok = RsaHelper.VerifyData("legacy-data", sign, pub, HashAlgorithmName.SHA256);
SM 系列
using Common.Security;
using Common.Security.Enums;
// SM3
var sm3 = Sm3Helper.GetSm3Hash("hello");
// SM4
var key = "1234567890123456";
var iv = "1234567890123456";
var cipherSm4 = Sm4Helper.Encrypt("hello", key, Sm4CryptoEnum.CBC, outType: OutType.Base64, iv: iv);
var plainSm4 = Sm4Helper.Decrypt(cipherSm4, key, Sm4CryptoEnum.CBC, inputType: OutType.Base64, iv: iv);
// SM2
var (publicKey, privateKey) = Sm2Helper.ExportKey(OutType.Hex);
var cipherSm2 = Sm2Helper.Encrypt("hello", publicKey, publicKeyType: OutType.Hex, outType: OutType.Hex);
var plainSm2 = Sm2Helper.Decrypt(cipherSm2, privateKey, privateKeyType: OutType.Hex, inputType: OutType.Hex);

安全建议
- 新项目优先:
- 对称加密:
AesGcmHelper(GCM) - 非对称加密:
EncryptOaepSha256/DecryptOaepSha256 - 数字签名:
SignDataPss/VerifyDataPss
- 对称加密:
- DES/3DES 仅建议兼容历史系统,不建议新系统使用。
- 固定密钥、固定 IV、明文落库都会显著降低安全性。
兼容与迁移
AesGcmHelper中历史非 GCM 重载(Encrypt/Decrypt带CipherMode/PaddingMode)已标记[Obsolete]。- 迁移建议:
- 历史 AES 调用迁移到
AesHelper.Encrypt/Decrypt或AesHelper.EncryptCbcPkcs7/DecryptCbcPkcs7 - 新业务优先使用
AesGcmHelper的 GCM 重载
- 历史 AES 调用迁移到
