Hash Generator
A hash generator is a tool that creates a fixed-length hash value from input text using algorithms such as SHA-256, SHA-384, and SHA-512.
Quick answer
Supports SHA-1, SHA-256, SHA-384, and SHA-512.
Client-side only. Hashing is one-way and not encryption.
What this tells you
- •Supports SHA-1, SHA-256, SHA-384, and SHA-512.
- •Processing runs client-side in your browser and input is not sent to a server.
- •Hashing is one-way and not encryption, so hashes cannot be reliably reversed to original text.
How to Use
- 1Enter text input.
- 2Choose hash algorithm.
- 3Click Generate Hash and copy the output.
How It Works
Formula
Digest = HASH(algorithm, UTF-8 input bytes)The browser SubtleCrypto API computes a cryptographic digest and returns a hex-encoded string.
Calculation note: values are processed in the order shown above, using the current input units.

Common mistakes
- Treating hashes as encryption
- Expecting to decode hash back to plain text
- Using SHA-1 for new security-critical applications
Frequently Asked Questions
No. Hashing is one-way; encryption is reversible with a key.
