Time to crack passwords

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)
