(Chilkat2-Python) RSA Encrypt with Modulus and Exponent

Demonstrates how to RSA encrypt with a given modulus and exponent.

Chilkat2 Python Downloads install with pip pip3 install chilkat2 or download... Python Module for Windows, Linux, Alpine Linux, MacOS, Solaris

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

rsa = chilkat2.Rsa()

# Assuming you already have a base64 modulus and exponent,
# wrap it in XML like this:
modulus = "qMBRpdYrAy5aMmo31NErUizh5sbweguSmh4wlK6uJEIDl+kwTlROnE34KOFExeTbJSX0WygPi+vWl0yNq7buIMUKpytossAAWut5khO3CQJxTk7G2gnEPNUUXHiExGgNrLzcSLv8YIlfVALhoRWyC67KOL+a+3taNq3h+BHeWhM="
exponent = "AQAB"

xml = chilkat2.Xml()
xml.Tag = "RSAPublicKey"
xml.NewChild2("Modulus",modulus)
xml.NewChild2("Exponent",exponent)

# Encrypt with the public key.
publicKey = xml.GetXml()
