Below table represents estimated time to crack passwords based on passphrase lenght and complexity.

Of course time may differ depending on number of factors like:

• Using dictionary words in passwords may allow almost instant crack ( for example if “rainbow tables” are beign used)
• Hardwa used (CPU/GPU power, RAM etc.)
• Application used to crack password (how optimized is a code, programing language used etc.)
• Which symbols are included (more symbols longer time to crack)
