You have the system_hash key in config/blesta.php
but break that and your encryptions are all gone.
Edit:
HAHAHAHAHAH the password from a hash? Erm it's done with Bcrypt which is irreversible like Beav said. There's NO way you can reverse that unless you use a competitor who doesn't use it correctly.
Was it you that I chat with earlier? If yes, then it was the cron job - it wasn't set up on the server. In case any others have this issue, make sure you set up the 5 minute cron job. Settings > System > Automation shows what the command should be, but the cron must be created on your server.
