SHA-256 Hash Generator — Free Web Crypto Hashing for Files

Cách dùng

1. 1 Pick Text or File mode.
2. 2 Type / paste text, or choose a file (≤ 50 MB).
3. 3 Pick output encoding (hex or Base64).
4. 4 Copy the digest.

Vì sao dùng công cụ này

• Uses native Web Crypto API — hardware-accelerated where available.
• SHA-256 is approved for general security use, including signatures.
• Output in hex (64 chars) or Base64 (44 chars).
• Pure client-side — files never upload.

Câu hỏi thường gặp

SHA-256 Hash Generator là gì?

A SHA-256 Hash Generator is a tool that computes the SHA-256 message digest of text or files, producing a fixed-length cryptographic checksum of the input. It uses the browser's native Web Crypto API to perform the hashing and outputs the result in hexadecimal or Base64 encoding. The computation runs entirely in the browser, so the data being hashed is processed client-side and is never uploaded to a server.
