About File Hash Calculator
Calculate cryptographic hash values of your files to verify integrity and authenticity. Hash values are unique fingerprints that change if even a single byte of the file is modified.
MD5: 128-bit hash, fast but not cryptographically secure
SHA-1: 160-bit hash, deprecated for security purposes
SHA-256: 256-bit hash, widely used and secure
SHA-384: 384-bit hash, higher security than SHA-256
SHA-512: 512-bit hash, maximum security
Common use cases: Verify file downloads, detect file corruption, ensure file integrity, compare files without transferring them
