Frequently Asked Questions
Is my data secure?▾
Yes, all hashing is performed in your browser using the Web Crypto API. No data is ever sent to any server.
Why is MD5 not included?▾
MD5 is cryptographically broken and not supported by the Web Crypto API. We recommend using SHA-256 or SHA-512 instead for security-critical use cases.
Can I hash files?▾
Yes, use the file input to select a file. The file is read in your browser and hashed locally without uploading.
What hash algorithm should I use?▾
For general use, SHA-256 is the most widely recommended. SHA-512 offers a longer hash. SHA-1 is included for legacy compatibility but is no longer considered secure for cryptographic purposes.
Can I use this to verify file integrity?▾
Yes. Upload a file and generate its hash, then compare it against the expected hash provided by the file source. If the hashes match, the file has not been tampered with or corrupted during download.
What is the maximum file size I can hash?▾
The file is read entirely into memory in your browser, so the practical limit depends on your device. Most modern browsers can handle files up to several hundred megabytes without issues.
Can I use this tool on my phone?▾
Yes, the hash generator works in any modern mobile browser. You can hash text input or upload files directly from your phone.
