Login Dataset for COSC 520 Login Checker

A synthetic dataset of usernames for benchmarking how quickly different data structures (linear search, binary search, hash table, Bloom filter and Cuckoo filter) can check whether a login is already taken. logins.txt: 10,000,000 unique logins, one per line absent_logins.txt: 100,000 logins that are not in logins.txt, used to test lookups for new users and to measure false-positive rates Logins mix name-based (sara.patel), word-based (blue.moon874) and random (x7kq2pzd) patterns, with an average length of 11.6 characters. The data is fully synthetic and contains no real user information. It can be regenerated exactly with seed 520 using the code at https://github.com/smahdieh/COSC-520---login-checker.
