sys.pkey_decrypt()

Purpose:

sys.pkey_decrypt() decrypts a publickey encrypted/base64 encoded piece of text

Usage:

cleartext = sys.pkey_decrypt(<pkeyname>,<b64text>,<encodingtype>);

Arguments:

alpha - <pkeyname> - The name used by the application when opening the private key.

alpha - <b64text> - The encrypted and encoded text to decode and decrypt

Returns:

<cleartext> - The cleartext that was originally encrypted and encoded.

"" - Some error

Where Used:

sys.pkey_decrypt() can be called from anywhere as long as you have a valid private RSA key open.

Example:

The demo program demo.pkey.1 has an example of using a public/private key to encrypt and then using only the private key to decrypt a small amount of text. If you try to do this with too large a piece of text you will see that it fails at a fairly small length.

Description:

sys.pkey_decrypt() will use an open private key to decrypt a small amount of base64 encoded text. amount of text.
