Frequently Asked Questions
No. All hashing is performed entirely in your browser using the Web Crypto API. Your data never leaves your device.
SHA-1, SHA-256, SHA-384, and SHA-512 are supported. These are all part of the SHA-2 family (except SHA-1) and are provided natively by the Web Crypto API.
Yes! You can paste text directly or upload any file. The tool hashes the raw bytes of the file.
SHA-1 is considered cryptographically weak and should not be used for security-critical applications like certificate signing. Use SHA-256 or SHA-512 instead.
