Hash Generator
Generate SHA hashes from text or files
Last updated:Hash generation computes cryptographic digests (SHA-1, SHA-256, SHA-384, SHA-512) of any text input — useful for verifying message integrity, comparing API responses, or generating stable identifiers. LlamaPDF uses the browser's native crypto.subtle.digest API, so your input is never transmitted anywhere.

How to generate a hash
- 1
Type or paste the text you want to hash into the input field above.
- 2
Select your hash algorithm — MD5, SHA-1, SHA-256, or SHA-512. Each produces a fixed-length fingerprint of your input.
- 3
Your hash is generated instantly. Copy the result to your clipboard. All hashing is performed in your browser using native cryptographic APIs — your input text is never sent anywhere.
Why use our hash generator?
Hashing is a fundamental tool for verifying data integrity, comparing file contents, and working with checksums. Developers use hashes to validate downloads, check for data tampering, and implement security features. Our generator supports the most widely used algorithms — MD5, SHA-1, SHA-256, and SHA-512 — and produces results instantly. It is also useful for generating unique identifiers from strings or confirming that two pieces of text are identical without sharing the original content.
All hashing runs in your browser using native Web Crypto APIs, so your input is never sent to a server. Need to encode data rather than hash it? Try our Base64 encoder or URL encoder for reversible transformations. You can also protect your PDFs with a password for document-level security.
