sys.pkey_verify()

Purpose:

sys.pkey_verify() verifies a the signature for a string of text using public key cryptography.

Usage:

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

Arguments:

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

alpha - <text> - The data to verify

alpha - <sig> - The signature to verify

Returns:

0 - Signature verified.

-1 - Signature verify failed.

Where Used:

sys.pkey_verify() can be called anytime the application has an open public/private key that they want to use to verify the digital signature of a string of text.

Example:

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

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

Description:

sys.pkey_verify() uses public key cryptography to verify the digital signature of a string of text. The application must have open either the public or the private key corresponding to the private key that was used to digitally sign the text.

Requirements

sys.pkey_open() requires 4CServer Version 4.6.1 or higher
