About SHA-256 Generator
Generate a SHA-256 cryptographic hash from any text string or file directly in your browser using the Web Crypto API. SHA-256 produces a 256-bit (64 hex character) digest that is a one-way fingerprint of the input. Use it to verify file integrity, store password hashes, create content fingerprints, or validate API message signing. The hash updates in real time as you type. For files, the tool streams the content through the hash function so even large files are handled without excessive memory usage. All computation is client-side –no data is sent anywhere.
Frequently Asked Questions
Can I hash a file, not just text?
Yes. Drop or select a file to compute its SHA-256 hash for integrity verification.
Is SHA-256 suitable for password hashing?
Raw SHA-256 is not recommended for passwords. Use a dedicated password hashing algorithm like bcrypt or Argon2 instead.
What format is the output?
The hash is displayed as a lowercase hexadecimal string (64 characters).
