A cryptographic hash function takes any input and produces a fixed-length output (the hash). Even a tiny change in the input produces a completely different hash. Hashes are used to verify file integrity and store passwords securely.

Is MD5 still safe to use?

MD5 and SHA-1 are cryptographically broken and should not be used for security purposes. They are shown for legacy compatibility only. For any security application use SHA-256 or stronger.

How do I verify a file download?

Download the file, then drag and drop it into the Hash Generator above. Compare the SHA-256 hash shown against the checksum published on the download page. If they match the file is authentic and untampered.
