.NET 解密加密

前言

 在日常开发过程中，不可避免的涉及到数据加密解密（Hash）操作，所以就有想法开发通用工具，NETCore.Encrypt就诞生了。目前NETCore.Encrypt只支持.NET Core ,工具包含了AES,DES,RSA加密解密，MD5，SHA*,HMAC*等常用Hash操作。

通过Nuget安装

Install-Package NETCore.Encrypt -Version 2.0.8

AES 操作

创建AES 秘钥

var aseKey = EncryptProvider.CreateAesKey();
 
var key = aesKey.Key;
var iv = aesKey.IV;

 

 AES 加密

var srcString = "aes encrypt";
//不带加密向量
var encrypted = EncryptProvider.AESEncrypt(srcString, key);

 

var srcString = "aes encrypt";
//带加密向量
var encrypted = EncryptProvider.AESEncrypt(srcString, key, iv);

 

//对byte[] 进行aes加密（version 2.0.6）
var srcBytes = new bytes[]{xxxx};
//带加密向量
var encryptedBytes = EncryptProvider.AESEncrypt(srcBytes , key, iv);　

AES 解密

var encryptedStr = "xxxx";
//不带加密向量（与加密方式对应）
var decrypted = EncryptProvider.AESDecrypt(encryptedStr, key);

 

var encryptedStr = "xxxx";
//带加密向量
var decrypted = EncryptProvider.AESDecrypt(encryptedStr, key, iv);

　　

//对byte[] 进行aes解密（version 2.0.6）
var encryptedBytes = new bytes[]{xxxx};
//带加密向量
var encryptedBytes = EncryptProvider.AESDecrypt(encryptedBytes , key, iv);

DES 操作

创建DES 秘钥

//秘钥长度为24
var desKey = EncryptProvider.CreateDesKey();

DES加密

var srcString = "des encrypt";
var encrypted = EncryptProvider.DESEncrypt(srcString, key);

 

//对byte[] 进行des加密（version 2.0.6）
var srcBytes = new bytes[]{xxxx};
var encryptedBytes = EncryptProvider.DESEncrypt(srcBytes , key);

DES解密

var encryptedStr = "xxxx";
var decrypted = EncryptProvider.DESDecrypt(encryptedStr, key);　

 

//对byte[] 进行des解密（version 2.0.6）
var encryptedBytes = new bytes[]{xxxx};
var decryptedBytes = EncryptProvider.DESDecrypt(decryptedBytes , key)　

RSA 操作

 RSA秘钥长度枚举 

public enum RsaSize
{
    R2048=2048,
    R3072=3072,
    R4096=4096
}

 创建RSA秘钥

var rsaKey = EncryptProvider.CreateRsaKey();    //default is 2048
 
// var rsaKey = EncryptProvider.CreateRsaKey(RsaSize.R3072);
 
var publicKey = rsaKey.PublicKey;
var privateKey = rsaKey.PrivateKey;
var exponent = rsaKey.Exponent;
var modulus = rsaKey.Modulus;

 RSA加密 Sign 和 Verify 方法

string rawStr = "xxx";
string signStr = EncryptProvider.RSASign(rawStr, privateKey);
bool   result = EncryptProvider.RSAVerify(rawStr, signStr, publicKey);　

 RSA加密

var publicKey = rsaKey.PublicKey;
var srcString = "rsa encrypt";
 
var encrypted = EncryptProvider.RSAEncrypt(publicKey, srcString);
 
//on mac/linux at version 2.0.5
var encrypted = EncryptProvider.RSAEncrypt(publicKey, srcString, RSAEncryptionPadding.Pkcs1);

 RSA解密

var privateKey = rsaKey.PrivateKey;
var encryptedStr = "xxxx";
var decrypted = EncryptProvider.RSADecrypt(privateKey, encryptedStr);
 
//on mac/linux at version 2.0.5
var decrypted = EncryptProvider.RSADecrypt(privateKey, encryptedStr, RSAEncryptionPadding.Pkcs1);

通过RSA秘钥创建RSA

var privateKey = rsaKey.PrivateKey;
RSA rsa = EncryptProvider.RSAFromString(privateKey);

RSA 和 PEM 相互转换

//Rsa to pem format key
 
//PKCS1
var pkcs1KeyTuple = EncryptProvider.RSAToPem(false);
var publicPem = pkcs1KeyTuple.publicPem;
var privatePem = pkcs1KeyTuple.privatePem;
 
//PKCS8
var pkcs8KeyTuple = EncryptProvider.RSAToPem(true);
publicPem = pkcs8KeyTuple.publicPem;
privatePem = pkcs8KeyTuple.privatePem;
 
//Rsa from pem key
 
var rsa = EncryptProvider.RSAFromPem(pemPublicKey);
rsa = EncryptProvider.RSAFromPem(pemPrivateKey);
 
//Rsa encrypt and decrypt with pem key
 
var rawStr = "xxx";
var enctypedStr = EncryptProvider.RSAEncryptWithPem(pemPublicKey, rawStr);
var decryptedStr = EncryptProvider.RSADecryptWithPem(pemPrivateKey, enctypedStr);

HASH 操作

 MD5

var srcString = "Md5 hash";
var hashed = EncryptProvider.Md5(srcString);

 SHA

var srcString = "sha hash";   
//SHA1
var hashed = EncryptProvider.Sha1(srcString);
//SHA256
var hashed = EncryptProvider.Sha256(srcString);
//SHA384
var hashed = EncryptProvider.Sha384(srcString);
//SHA512
var hashed = EncryptProvider.Sha512(srcString);

 HMAC

var key="xxx";
var srcString = "hmac hash";    
 
//MD5
var hashed = EncryptProvider.HMACMD5(srcString,key);
//HMACSHA1
var hashed = EncryptProvider.HMACSHA1(srcString,key);
//HMACSHA256
var hashed = EncryptProvider.HMACSHA256(srcString,key);
//HMACSHA384
var hashed = EncryptProvider.HMACSHA384(srcString,key);
//HMACSHA512
var hashed = EncryptProvider.HMACSHA512(srcString，key);

BASE64 操作

Base64加密

var srcString = "base64 string";   
var hashed = EncryptProvider.Base64Encrypt(srcString);   //default encoding is UTF-8
 
//Encoding.ASCII
var hashed = EncryptProvider.Base64Encrypt(srcString,Encoding.ASCII);  

Base64解密

var encryptedStr = "xxxxx";   
var strValue = EncryptProvider.Base64Decrypt(encryptedStr);   //default encoding is UTF-8
 
//Encoding.ASCII(需要与加密编码对应)
var strValue = EncryptProvider.Base64Decrypt(encryptedStr,Encoding.ASCII);
