Today I would like to discuss the entropy of a phrase based password.
Phrase Based Password
A phrase based password is a password assembled from several easy to remember and spell words, delimited by spaces.
As a result, such passwords are very [...]
A common and easy way to estimate the strength of a password is its entropy.

The entropy measures the number of [...]
In this article I will explain the method I suggest for hashing password and saving them in a database.
