About Hash Functions

What are Hash Functions?

Hash functions are algorithms that convert input data of any size into a fixed-size string of characters. They are one-way functions, meaning you cannot reverse the process to get the original input.

Common Uses

  • ✅ Password storage (with salting)
  • ✅ File integrity verification
  • ✅ Digital signatures
  • ✅ Data deduplication
  • ✅ Checksum validation

Security Notes

  • MD5: Not secure for cryptographic purposes. Use only for checksums.
  • SHA-1: Deprecated for security. Avoid for new applications.
  • SHA-256: Secure and widely used. Recommended for most applications.
  • SHA-512: Most secure. Use for high-security applications.
