 ## BCryptHasher
 
-BCrypt is a password hashing function that automatically incorporates salts to increase security. It also offers a configurable work factor that increases the amount of computational resources required to generate a hash ([key stretching](https://en.wikipedia.org/wiki/Key_stretching)).
