What is a Hash?
A hash function converts input data into a fixed-size string of characters, which acts as a digital fingerprint.
Security Uses
Hashes are used for data integrity verification, password storage, digital signatures, and file identification.

đ Security Recommendations
Avoid MD5/SHA1 for Security
MD5 and SHA-1 are cryptographically broken and vulnerable to collision attacks. Never use them for passwords or security-sensitive applications.
Use SHA-256 or SHA-512
For security-critical applications, use SHA-256 or SHA-512. These are currently considered secure against all known attacks.
Always Salt Passwords
When hashing passwords, always use a unique salt for each user to prevent rainbow table attacks. Use algorithms like bcrypt or Argon2 specifically designed for passwords.
Consider SHA-3/Keccak
For future-proof security, consider using SHA-3 (Keccak) which uses a completely different design from SHA-2 and is resistant to length-extension attacks.
