Hash Generator
Generate SHA-256, SHA-1, SHA-384, and SHA-512 hashes from any text. Runs entirely in your browser using the Web Crypto API.
Tip: Press Ctrl+Enter (or Cmd+Enter) to generate.
What is a Hash Generator?
A hash generator takes any input text and produces a fixed-length string of characters using a cryptographic algorithm. Hash functions are one-way: the same input always produces the same hash, but it's computationally infeasible to reverse the hash back to the original text. Hashing is used to verify file integrity, store passwords securely, create digital signatures, and detect data tampering. Our generator uses the browser's built-in Web Crypto API, so your text never leaves your device.
How to use the Hash Generator
- 1Type or paste the text you want to hash into the input area.
- 2Click "Generate Hashes" (or press Ctrl+Enter).
- 3All four hash algorithms run simultaneously: SHA-1, SHA-256, SHA-384, and SHA-512.
- 4Copy any individual hash using the Copy button next to it.
Common uses
- →Verifying file integrity by comparing hash values before and after transfer
- →Learning about cryptographic hash functions for security coursework
- →Generating checksums for software packages and downloads
- →Testing hash-based authentication and data validation logic in development
Frequently asked questions
+What is a hash function?
A hash function converts any input text into a fixed-length string of characters. The same input always produces the same hash, but the input cannot be recovered from the hash.
+Which hash algorithm should I use?
Use SHA-256 or SHA-512 for security-sensitive applications. SHA-1 is outdated and should be avoided for cryptographic purposes. SHA-384 is a good middle ground.
+Is MD5 supported?
MD5 is not available via the browser's built-in Web Crypto API, which we use to ensure security. We support SHA-1, SHA-256, SHA-384, and SHA-512 instead.
