About Hash Generator
Calculate cryptographic message digests and file checksums instantaneously. Hash plain text strings or verify local file integrity by computing MD5, SHA-1, SHA-256, SHA-384, and SHA-512 digests using the hardware-accelerated Web Crypto API.
Frequently Asked Questions
Is my file uploaded when calculating a hash?
No. The file hash is calculated locally inside your browser using chunked ArrayBuffer streams. Zero bytes are uploaded to the internet.
What is a hash used for?
Fingerprints for files and passwords: the same input always gives the same hash, which lets you verify data has not changed.
Which algorithms are included?
MD5, SHA-1, SHA-256 and SHA-512 are generated together. SHA-256 is the recommended all-round choice.
