Crypto.RSAEncrypt(Data As MemoryBlock, PublicKey As String) As MemoryBlock

New in 2013r4

Supported for all project types and targets.

Encrypts the data using the specified PublicKey.

Notes

Attempting to encrypt using a PrivateKey raises a CryptoException.

Sample Code

Encrypt some text:

Var privateKey As String
Var publicKey As String

If Crypto.RSAGenerateKeyPair( 1024, privateKey, publicKey ) Then
// 1024-bit private and public keys were generated

Const kMessage = "this is a test"

Var msg As New MemoryBlock(14)
msg.StringValue(0, 14) = kMessage

// Encrypt msg using the publicKey
Var encryptedData As MemoryBlock = Crypto.RSAEncrypt( msg, publicKey )

If encryptedData <> Nil Then
MessageBox("Successfully encrypted.")
End If
End If
