512 bitsWhat is a Hash?
A hash is an algorithm that maps data of arbitrary length to a fixed-length digest. The same input always produces the same output, while a tiny change in input produces a completely different output. It is impossible to reverse a hash value back to the original data.
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
- File integrity verification: compare hash values after download to confirm files are not tampered with
- Password storage: systems store hash values instead of plaintext passwords
- Data deduplication: quickly determine if data is identical via hash values
- Digital signatures: used as message digest for signature verification
