.NET Core RSA algorithm using the help tool.It supports data encryption, decryption, signature and verification signature.It supports three key formats, namely: xml, pkcs1, pkcs8.It also supports key conversion for these three formats.Last also support pem formatting.

Install-Package XC.RSAUtil

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

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];

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

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

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

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

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

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

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

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()

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()
