Hash Generator
Hash text with SHA-256, SHA-1, or MD5 in your browser.
Tool workspace
Hashes UTF-8 text in your browser (Web Crypto for SHA-256/SHA-1; pure JS for MD5). Nothing is uploaded.
How it works
Paste text, choose SHA-256, SHA-1, or MD5, and Hex or Base64 output.
SHA-256 and SHA-1 use Web Crypto. MD5 uses a local pure implementation (Web Crypto does not provide MD5).
Empty input clears the result—no error. Hashes are not passwords and do not imply security by themselves.
