Cryptographic Hash & File Checksum Generator
Calculate cryptographic hash digests (SHA-256, SHA-512, SHA-1, MD5) for text and files locally using the native Web Crypto API. Fast, accurate, and completely private.
如何使用此工具
- Enter text or select a file to compute checksums.
- View generated hashes in real-time across multiple algorithms.
- Copy any hash value with a single click.
常见问题解答
Are my files uploaded to generate the checksum?
No, files are streamed and processed entirely in memory via the browser Web Crypto API.
Which algorithm is best for password security?
SHA-256 and SHA-512 are cryptographic standard functions with strong collision resistance.
