- Anti-leech timing adjust.
- Time given after download link been loaded by your website. After the period end download link will be expired or unavailable.
- Anti-spam ability (captcha).
- Another security purpose to bother visitors with. In case you care to use it.
- Additional character for token.
- Put any character to produce more unique value of the token. This will make your token different with others who also using this plugin.
- Popup’s ON/OFF ability.
- More secure if set to default: YES. No pop-up, will make security rely only on token’s encryption code.

Hello!
I love your “Risal Download” plugin. Thank you for creating it and offering it! If more people knew and understood exactly what Risal Download does, there would be tremendous demand for this product. You have created one of the best methods for protecting documents from unauthorized access and download. When Risal Download is used in combination with a page access plugin, (e.g., any of the various plugins that restrict page access based on user login permissions), document download links become extremely well protected.
One question: I’ve noticed that Risal Download’s implementation of pop-ups and captcha both work very well on PCs, but these options do not appear to work when a Mac is visiting the web page containing those Risal options. In order for the page to be usable by Mac users, I have needed to turn off pop-ups and captcha in the Risal options. Do you know what might be causing that problem? It would be ideal if Risal Download created links that work well for PCs and Macs.
Thank you again!
