SHA hash generator
Turn text or a file up to 100 MB into a hexadecimal SHA digest using the Web Crypto API in your browser. Useful for integrity checks, development, and learning.
Three steps.
Zero uploads.
- 01
Paste text or optionally choose a local file.
- 02
Choose SHA-256, SHA-384, or SHA-512.
- 03
Copy the hexadecimal digest.
Secure randomness is one part of security.
KeyWoven uses browser cryptography where the tool requires randomness, but it does not certify a system or make any result unbreakable. Unique storage, multi-factor authentication, rate limits, trusted devices, and the policy of the service using the value still matter.

Hash generator FAQ
Is a hash the same as encryption?+
No. Encryption is designed to be reversed with a key; a cryptographic hash is a one-way digest of the input.
Can I hash sensitive text here?+
The calculation happens locally and KeyWoven does not receive the text. Still, avoid exposing secrets on a device or browser you do not trust.
Should I store passwords as a plain SHA hash?+
No. Password storage should use a purpose-built, salted, slow password hashing function such as Argon2, scrypt, or bcrypt.
