Voucher Generators

The Voucher Server supports generation of Vouchers utilizing different generation methods via the concept of Voucher Generators.

Each Voucher Generator specifies unique generation properties to utilize when generating a Voucher Batch.

The current supported Generation Functions are:

Numeric

The current supported encryption formats are:

Unencrypted
HMAC (SHA)

To access the Voucher Generators search page, select the Voucher Generators menu link.

All configured Voucher Generators will be shown with standard features for searching and sorting available via the table controls.

Double clicking a row or clicking the edit icon will display the Voucher Generator details page.

In the example screenshot the configured Voucher Generator 15-digit HMAC SHA384 is configured as an active Voucher Generator, with its Voucher Generation generating 15 character numeric Vouchers which are encrypted utilizing an HMCA SHA384 encryption algorithm.

Note: After their initial creation Voucher Generator generation and encryption properties may not be changed.
