Type text or choose a file to instantly get its MD5 and SHA hashes, and paste a published checksum to check that the file is intact.
Your files never leave your device
Open the File tab and choose the downloaded file. Copy the checksum from the developer's website and paste it into the compare box. The tool finds which algorithm matches and highlights it; if nothing matches, download the file again.
A short fixed-length fingerprint calculated from data. The same input always gives the same hash, and even a tiny change gives a completely different one.
Choose the file, then paste the checksum published by the developer into the compare box. A match means the file is complete and unchanged.
No. The file is read and hashed on your device; it never leaves it.
SHA-256 is the common choice today. MD5 and SHA-1 are still used for checksums but are no longer secure against deliberate tampering.
No. Hashing is one-way. Short or common texts can still be guessed, so use proper password hashing for storing passwords.
Yes, but the whole file is loaded into memory, so files of several gigabytes may fail on phones.
