MD5 and SHA-1 can detect accidental corruption but must not be relied on against a deliberate attacker.
Enter text or choose a non-empty file to see its digests.
Frequently asked questions
How long is an MD5 digest?
MD5 produces 128 bits, shown as 32 hexadecimal characters. This Tool hashes the UTF-8 bytes of text or the exact bytes of a chosen file.
Can MD5 prove a download is authentic?
No. MD5 has lost collision resistance: an attacker can construct different messages with the same digest. It remains useful for accidental corruption checks and legacy SSH fingerprints, but use a trusted signature to establish authenticity.
Why is there a 100 MB file cap?
Files are read whole and hashed in your browser. The 100 MB cap limits memory use and time spent computing MD5 on the main thread. No file is uploaded.
