Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text input or file uploads. All hashes are computed at once for easy comparison.
How to Use This Hash Generator
Enter text in the input field and click Generate Hashes, or upload a file to compute hashes from its contents. The tool generates all four hash types simultaneously: MD5, SHA-1, SHA-256, and SHA-512. Click Copy next to any hash to copy it to your clipboard. SHA variants use the Web Crypto API (SubtleCrypto) for fast, native performance.
Hash Algorithm Comparison
MD5 produces a 128-bit hash and is fast but not collision-resistant. SHA-1 produces a 160-bit hash and is deprecated for security use. SHA-256 and SHA-512 are part of the SHA-2 family and are widely used for security applications, digital signatures, and file integrity verification.
Frequently Asked Questions
Is my data safe?
Yes. All hashing happens in your browser using the Web Crypto API and a local MD5 implementation. No data is sent to any server.
Can I hash large files?
Yes. The file is read into memory in your browser. Performance depends on your device, but files up to several hundred megabytes typically work fine.
