' This example assumes the Chilkat API to have been previously unlocked.

' RSA public key in XML format:

' To use Optimal Asymmetric Encryption Padding (OAEP) padding,
' simply set the OaepPadding property:
rsa.OaepPadding = True

' Encrypt a string and return the encrypted data base64-encoded:
rsa.EncodingMode = "base64"
