SecuroCheck is a password strength check utility based on web technologies.
- A variety of features:
- Color-feedback: Based on password strength, which is calculated using character categories
- Cracking time estimation: Estimates how long it would take a modern GPU to crack the password using brute force.
- Character category detection: Identifies the use of different character types, which strengthens passwords.
- Weak pattern detection: Detects weak patterns, like sequences and repeated characters.
- Common password detection: Compare against commonly used passwords using a pre-compiled list of 10 million passwords.
- Unicode: Accounts and handles for non-ASCII Unicode characters, like math symbols and emojis.
Strength Estimation: via brute-force, which is trying out all possible combinations of characters possible until the right password is found. The code calculates the entropy of the password, using the formula entropy = password length x log2(strength) and time to crack = strength ^ password length / guesses per second. Character property detection is implemented, checking if the password includes numbers, lowercase, whitespace, Unicode characters etc.

- Performance: The password strength calculation and cracking time estimation uses a modern GPU's brute force speed, 100 trillion guesses per second. This however, is quite subjective.
