Which algorithms are supported?

SHA-256, SHA-384, SHA-512, and SHA-1 via Web Crypto.

No. Hashing runs locally in the browser.

What encoding is used?

UTF-8 text is hashed; output is lowercase hexadecimal.

Can I hash binary files?

Paste text content. For files, use CLI checksum tools.

Is SHA-1 still useful?

Included for legacy systems; prefer SHA-256 for new work.

Does this replace HMAC?

No. Use dedicated HMAC tooling when a secret key is required.

Generate SHA-256, SHA-384, SHA-512, and SHA-1 hex digests from text using Web Crypto—no server upload.

Hashing for debugging and verification

Developers hash strings for cache keys, checksum verification, and comparing webhook signatures. A hash generator online using Web Crypto matches what modern browsers expose to client apps.

Security notes

This tool is for debugging and checksum workflows, not password storage. Never treat client-side hashing as a replacement for server-side password hashing with salts.

How it works

1Enter plain text and select a SHA algorithm.
2Web Crypto computes the digest locally and shows lowercase hex output.
3Copy the hash into scripts, tickets, or comparison notes.

Examples

SHA-256 of a short string

developer-tools-hub

SHA-512 for cache key material

cache:user:42:preferences

SHA-384 sample

webhook-payload-v3

SHA-1 legacy checksum

legacy-integration-token

When to use this tool

Compute SHA-256 checksums for config snippets.
Compare hashed values from API documentation.
Generate digests for cache-busting keys.
Verify sample HMAC payloads during integration work.
Test idempotency keys before sending requests.
Document expected hash outputs in runbooks.
