Documentation

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

List<string> keyList = RsaKeyGenerator.XmlKey(2048);
string privateKey = keyList[0];
string publicKey = keyList[1];

Format: Pkcs1

List<string> keyList = RsaKeyGenerator.Pkcs1Key(2048);
string privateKey = keyList[0];
string publicKey = keyList[1];

Format: Pkcs8

List<string> keyList = RsaKeyGenerator.Pkcs8Key(2048);
string privateKey = keyList[0];
string publicKey = keyList[1];

RSA key conversion

Use class RsaKeyConvert. It supports key conversion for xml, pkcs1 and 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()
