A collection of Java command-line tools demonstrating core cybersecurity concepts.

Evaluates password strength using composition rules, entropy calculation, and comparison against commonly leaked passwords.

Encrypts and decrypts text files using a byte-level XOR cipher, demonstrating file I/O and basic cryptographic principles.

These projects were built to apply and demonstrate practical cybersecurity concepts using Java, combining secure coding practices with an understanding of common attack patterns (credential stuffing, brute-force resistance).
