sys.pkey_sign()

Purpose:

sys.pkey_sign() uses an open private key to digitally sign a string of text.

Usage:

sig = sys.pkey_sign(<pkeyname>,<text>);

Arguments:

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

alpha - <text> - The data to sign

Returns:

alpha - <sig> - The digital signature of the text

"" - Error

Anything else - the digital signature of the text.

Where Used:

sys.pkey_sign() can be called anytime the private key is open.

Example:

The following Demo programs have examples of using sys.pkey_sign()

• demo.pkey.1
• demo.pkey.2
• demo.serial.cr

Description:

sys.pkey_sign() uses the open private key to create the digital signature for a string of text. The application may store this signature and use sys.pkey_verify() somewhere else in the application to verify that the signed text has not been modified.
