Hash Generator

Developer

Generate SHA-256, SHA-512, SHA-1, and SHA-384 hashes from text or files. All processing happens locally in your browser.

256 bits (64 hex chars)

0 / 10,000,000 characters

All hashing is performed entirely in your browser using the Web Crypto API. No text or file content is sent to any server.

Enter text above to generate a hash.

Paste an expected hash to compare it against the computed result. Comparison is case-insensitive.

MD5 is not included because it's cryptographically broken and cannot be used safely. SHA-256 is the recommended alternative.

How to Use

1Choose input mode: Text for typing or pasting content, File for hashing any file.
2For text: type or paste your content into the text area.
3For files: drag and drop or click to upload any file up to 100 MB.
4Select the hash algorithm: SHA-256 is recommended for most purposes.
5Copy the hash in your preferred format: lowercase hex, uppercase hex, or Base64.
6Optionally paste an existing hash in the Verify section to check if it matches.

Verify file integrity: confirm a downloaded file matches its published hash

Understand password hashing: see how passwords are stored (never store plaintext)

Data deduplication: detect duplicate files by comparing hashes

Digital signatures: understand the foundation of code signing

Checksums: verify data hasn't been corrupted during transfer

Learning: explore how cryptographic hash functions work
