About File Hashing

Cryptographic hash functions generate unique fixed-size strings (hashes) from input data. They are one-way functions, making it nearly impossible to reverse the process.

MD5

128-bit hash. Fast but not recommended for security. Good for checksums and non-security purposes.

SHA-1

160-bit hash. Better than MD5 but deprecated for security. Still used in Git and legacy systems.

SHA-256

256-bit hash. Current security standard. Widely used in cryptography, blockchain, and secure applications.

Common Use Cases

  • File integrity verification (detect corruption or tampering)
  • Download verification (compare with official checksums)
  • Password storage (hashing before database storage)
  • Digital signatures and certificates
  • Blockchain and cryptocurrency
  • Version control systems (Git uses SHA-1)
