Algorithms
This tool hashes pasted text in your browser and returns fixed-length SHA digests you can copy for verification and checksum workflows.
Why people use this tool
Hash Generator computes cryptographic hashes from text input using SHA-1, SHA-256, SHA-384, and SHA-512 algorithms. It is useful when you need a fast hash function for checksums, verification, signatures, or developer workflows without sending data to a server.
- Generate text-based checksums before comparing values across systems, logs, or API workflows.
- Create SHA hashes for signatures, verification steps, test fixtures, and developer documentation.
- Compare hash outputs to confirm whether two text inputs are identical without reviewing every character.
How to use it
- 1Enter or paste the text you want to hash.
- 2Click Generate to compute SHA-1, SHA-256, SHA-384, and SHA-512 hashes.
- 3Copy the hash value you need for your workflow.
FAQ
Helpful answersWhat is a hash function?
A hash function takes input data and produces a fixed-length string of characters. The same input always produces the same output, but you cannot reverse it.
Which hash algorithm should I use?
SHA-256 is the default choice for most general verification tasks. SHA-384 and SHA-512 are useful when a workflow specifically requires longer digests. SHA-1 still appears in legacy systems but is no longer recommended for security-sensitive use.
Can I hash files with this tool?
This version hashes text input only. It is best suited to pasted strings, tokens, payloads, snippets, and other text-based developer inputs.
Is this tool secure?
Yes. All hashing is done in your browser using the Web Crypto API. No data is sent to any server.
