It's strongly recommended to install BLENC from sources without 'pecl' command. In this way you can:
- Specify your personal encryption key used to create redistributable keys. Your sourcecode will be more difficult to decrypt also for users that can read your key_file on webserver.
- Specify a expiration date for the BLENC module. With expiration date you can decide that BLENC module on target system will work until a date. After that BLENC will not decrypt any files.
Please read the content of blenc_protect.h in sources of BLENC to know how set these hardcoded options.
