Hash Generator
Calculate SHA-1, SHA-256, SHA-384 or SHA-512 hashes from text and copy the digest for verification.
FreeBrowserAbout Hash Generator
Calculate a SHA digest for text using SHA-1, SHA-256, SHA-384 or SHA-512. Copy the hexadecimal result when comparing exact message contents or debugging a checksum input.
When to use this tool
- Compare configuration text across environments.
- Check the exact input used in a message digest workflow.
Limits to know before using it
Whitespace and line breaks change the digest. A hash is not encryption or a keyed signature. SHA-1 is unsuitable for new security-sensitive designs; use File Checksum for files.
Data handling and cost

Frequently Asked Questions
No. Hashes are generated locally in your browser using Web Crypto. The input text and generated digests are not sent to any server.
The first version supports SHA-1, SHA-256, SHA-384, and SHA-512. MD5 is intentionally not included in the browser-native implementation and should not be used for security-sensitive workflows.
No. Fast hash functions are not appropriate for password storage. Use a dedicated password hashing algorithm such as Argon2, bcrypt, or scrypt with salts and tuned work factors.
