Even the best encryption algorithm does not help when the password used is easy to identify. SimpleumSafe rated the quality of your passphrase and estimates the time required to “crack” your password. To get a useful feedback about your password strength.
If an incorrect password was entered in SimpleumSafe, there will be a time lag until the next time you can enter a password again (2 seconds at the first attempt, then 4 sec. , 8 sec. 16 sec. and so on) .
A secure password ensures that it can not be guessed by targeted testing. A good encryption algorithm ensures that really all options (in AES-256 there are 2^255 possibilities) must be tried and there are no “shortcuts”.
