Hash Generator: Generate SHA-256, MD5, SHA-512 & SHA-1 Hashes

Calculate MD5, SHA-1, SHA-256, and SHA-512 cryptographic digests using browser-native Web Crypto APIs with zero server transmission.

Text Input to Hash

SHA-256

MD5

SHA-512

SHA-1 (Legacy)

How to Use Hash Generator

Enter any plain text or string to calculate SHA-256, MD5, SHA-1, and SHA-512 hashes simultaneously.
Copy the output with one-click copy buttons.

Practical Examples

Cryptographic Hash of "abc"

Verifies SHA-256 and MD5 test hashes.

Input:

abc

Output:

SHA-256: ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad
MD5: 900150983cd24fb0d6963f7d28e17f72

Common Mistakes & Troubleshooting

Attempting to reverse or crack cryptographic hashes: cryptographic hashes are mathematically irreversible one-way digests. FormatFlow never provides cracking tools.

Frequently Asked Questions

Are hash calculations performed on a server?

NO. All hashes are calculated locally on your CPU using the browser Web Crypto API and local TypeScript math. Nothing is transmitted over the network.
