RSADLL manual

Overview

The RSA algorithm was invented in 1978 by Ron Rivest, Adi Shamir, and Leonard Adleman. It is a public and private key cipher. The component includes an example of a public and private key, the seperate RSADLLKeyMaker component is required for creating valid keys. The component is limited to 40bit encryption.

Methods/Properties

Methods:

RSA.DeCrypt(Inp As String,d As Long,n As Long): Returns a string with the decrypted value.

RSA.Encrypt(Inp As String,e As Long,n As Long): Returns a string with the encrypted value.

Properties:

No properties.

Example

Below is a demonstration of using the RSADLL component, using the RSADLLKeyGenerator component.

<%


	Dim RSA,RSAKeyGen,encryptedData,decryptedData


	Dim e,d,n


	Dim plaintext





	Set RSA = Server.CreateObject("RSADLL.Crypt")


	Set RSAKeyGen = Server.CreateObject("RSADLL.RSAKeyGen")


	plaintext = "Good morning world"





	RSAKeyGen.GenerateKey





	encryptedData = RSA.Encrypt(plaintext,RSAKeyGen.e,RSAKeyGen.n)


	decryptedData = RSA.DeCrypt(encryptedData,RSAKeyGen.d,RSAKeyGen.n)




	Response.Write "Encrypting " & plaintext & "<BR>"


	Response.Write "Encrypted: " & encryptedData & "<BR>"


	Response.Write "Decrypted: " & decryptedData
