About Hash Functions

Hash functions convert data of any size into a fixed-size string. They are one-way functions — you cannot reverse a hash to get the original data.

Algorithm Comparison

  • MD5: Fast but cryptographically broken. Use only for checksums.
  • SHA-1: Deprecated for security. Avoid for new applications.
  • SHA-256: Recommended. Used in SSL, Bitcoin, and most security applications.
  • SHA-384/512: Stronger variants for high-security needs.

Common Use Cases

  • File integrity verification
  • Password storage (with salt)
  • Digital signatures
  • Data deduplication
