Which algorithms does the hash calculator support?
MD5, SHA-1, SHA-256 and SHA-512, computed simultaneously for text or files to ease comparison.
Hash vs encryption?
Hashing is one-way for integrity checks; encryption is reversible for protection. Hashes cannot recover the original — for verification, not secrecy.
How do I verify a downloaded file?
Compute its SHA-256 here and compare with the official checksum on the software site. Match means the file is intact and unmodified.
Is MD5 still safe?
MD5 has collision attacks — avoid it for security. Fine for casual checks, but use SHA-256/512 for anything important.
Is online hashing safe?
Safe. Files compute locally in your browser, never uploaded, suitable for sensitive content.
What is hashing best for?
Download verification, file dedup, salted password storage, integrity checks and release validation.
Are there limits on free use?
No. Free, no registration, with streaming support for large files.
How large a file can I hash?
Streaming computation handles multi-GB files without memory failure.
