About Cryptographic Hashes

• A hash function maps any input to a fixed-length output — the same input always produces the same hash.
• Hashes are one-way: you cannot recover the original text from a hash.
• MD5 and SHA-1 are broken for security use — prefer SHA-256 or higher.
• Never store plain passwords. Use bcrypt, Argon2, or scrypt instead.
• Even a single character change produces a completely different hash (avalanche effect).
