ℹ️ About Hash Functions
Hash functions are one-way cryptographic functions that convert input data into a fixed-size string of characters. They are commonly used for data integrity verification, password storage, and digital signatures.
MD5: Fast but cryptographically broken. Use only for checksums, not security.
SHA-1: Deprecated for security purposes. Avoid for new applications.
SHA-256: Currently recommended for most cryptographic purposes.
SHA-384/512: Stronger variants, useful for high-security requirements.
⚠️ Security Note: Hash functions are one-way. You cannot "decrypt" or reverse a hash to get the original data. For password storage, use dedicated password hashing algorithms like bcrypt or Argon2.
