Install

Install-Package XC.RSAUtil

The old package name is XC.Framework.Security.RSAUtil. Now renamed XC.RSAUtil and will continue to use.

Generate the key

Use class RsaKeyGenerator.The result returned is a list of two-element strings,Element 1 is the private key and element 2 is the public key.

Format: XML

var keyList = RsaKeyGenerator.XmlKey(2048);
var privateKey = keyList[0];
var publicKey = keyList[1];

Format: Pkcs1

var keyList = RsaKeyGenerator.Pkcs1Key(2048);
var privateKey = keyList[0];
var publicKey = keyList[1];

Format: Pkcs8

var keyList = RsaKeyGenerator.Pkcs8Key(2048);
var privateKey = keyList[0];
var publicKey = keyList[1];

RSA key conversion

Use class RsaKeyConvert.It supports key conversion for these three formats,namely: xml, pkcs1, pkcs8.

XML->Pkcs1:

Private Key : RsaKeyConvert.PrivateKeyXmlToPkcs1()
Public Key : RsaKeyConvert.PublicKeyXmlToPem()

XML->Pkcs8:

Private Key : RsaKeyConvert.PrivateKeyXmlToPkcs8()
Public Key : RsaKeyConvert.PublicKeyXmlToPem()

Pkcs1->XML:

Private Key : RsaKeyConvert.PrivateKeyPkcs1ToXml()
Public Key : RsaKeyConvert.PublicKeyPemToXml()

Pkcs1->Pkcs8:

Private Key : RsaKeyConvert.PrivateKeyPkcs1ToPkcs8()
Public Key : No conversion required

Pkcs8->XML:

Private Key : RsaKeyConvert.PrivateKeyPkcs8ToXml()
Public Key : RsaKeyConvert.PublicKeyPemToXml()

Pkcs8->Pkcs1:

Private Key : RsaKeyConvert.PrivateKeyPkcs8ToPkcs1()
Public Key : No conversion required

Encrypt, decrypt, sign, and verify signatures

XML, Pkcs1, Pkcs8 respectively corresponding categories: RsaXmlUtil, RsaPkcs1Util, RsaPkcs8Util.They inherit from the abstract class RSAUtilBase

Encrypt: RSAUtilBase.Encrypt()
Decrypt: RSAUtilBase.Decrypt()
Sign: RSAUtilBase.SignData()
Verify: RSAUtilBase.VerifyData()

PEM formatting

Use class RsaPemFormatHelper.

Format Pkcs1 format private key: RsaPemFormatHelper.Pkcs1PrivateKeyFormat()
Remove the Pkcs1 format private key format: RsaPemFormatHelper.Pkcs1PrivateKeyFormatRemove()
Format Pkcs8 format private key: RsaPemFormatHelper.Pkcs8PrivateKeyFormat()
Remove the Pkcs8 format private key format: RsaPemFormatHelper.Pkcs8PrivateKeyFormatRemove()

why i must input privatekey when decrypt. in fact , your code privatekey default value is null.
thank you.

加密长度问题

不知道有没有长度的解决方案？
我直接拿来跑不动..
提示参数错误
测试发现是加密传过长了

支持linux 吗？

是否支持Linux发布

Removing local BouncyCastle.Crypto and using NuGet package ?

I am not sure if you have a custom version of BouncyCastle for yourself in this project but if no, it would be good to use the original nuget package for easier update and fix ambiguous references while using BouncyCastle in my own project for other encryptions (AES, DES, ...)
