Frequently asked questions
What does the hash generator do?
The MarTools Hash Generator calculates SHA-1, SHA-256, and SHA-512 hash values from text or uploaded files directly in your browser.
Can I generate a hash from text online?
Yes. Enter or paste text into the hash generator to calculate its SHA-1, SHA-256, and SHA-512 hash values directly in your browser.
Can I generate a hash for a file?
Yes. Upload a file to calculate its SHA-1, SHA-256, and SHA-512 hashes. The file is processed in your browser.
How do I verify a file checksum?
Generate the hash of your local file using the same hashing algorithm as the trusted checksum, then compare the resulting hash values. Matching values indicate that the calculated data matches the reference hash.
What is the difference between SHA-1, SHA-256, and SHA-512?
They are different hashing algorithms that produce different digest lengths. SHA-1 produces a 160-bit digest, SHA-256 produces a 256-bit digest, and SHA-512 produces a 512-bit digest.
Is a hash the same as encryption?
No. Hashing and encryption are different concepts. Hashing produces a digest from input data, while encryption is designed to transform data so it can later be recovered with the appropriate key.
Are hashes calculated on a server?
No. MarTools calculates the hashes directly in your browser using the Web Crypto API, so the supported text or file data is not sent to a MarTools server for hashing.
