What is File Hash?
A file hash maps file content to a fixed-length digest using a specific algorithm. The same file always produces the same hash value, while any tiny change in content produces a completely different result. It is impossible to reverse a hash value back to the original file content.
Supported Algorithms
- MD5 - 128-bit digest, fast, not recommended for security purposes
- SHA-1 - 160-bit digest, collision vulnerabilities found, not recommended for security
- SHA-256 - 256-bit digest, widely used, secure and reliable, recommended for most use cases
- SHA-384/SHA-512 - 384/512-bit digest, higher security, suitable for high-security requirements
Common Use Cases
- Download verification: compare the downloaded file's hash with the official value
- File integrity check: detect if a file has been tampered with or corrupted during transfer
- Duplicate detection: quickly determine if two files have identical content via hash values
- Security auditing: use SHA-256 or higher to verify critical files haven't been tampered with
