About this tool
Generate a SHA-256 digest from text with the Web Crypto API. Processing happens locally in your browser, so your input is not sent to a server or included in analytics.
Frequently asked questions
Can SHA-256 hash passwords securely by itself?
No. Password storage requires a password hashing scheme such as Argon2id, scrypt, or bcrypt with salts and suitable work factors.
Is the text uploaded?
No. Web Crypto computes the digest in your browser.
Is this encryption?
No. Hashing is one-way and does not encrypt text for later decryption.
