This is a simple service that checks a password against a dictionary of common passwords. The service then returns a response informing the caller whether or not the password is common.
The server loads a dictionary of passwords, then creates a bloom filter in order to efficiently check the input password for presence in the dictionary. False positives are possible but unlikely.
