Frequently Asked Questions
Via the browser's own native, standards-compliant SHA-1 implementation (crypto.subtle.digest), not a custom or approximate one.
No — SHA-1 has known practical collision attacks and is deprecated for security use (signatures, certificates). It's still fine for non-adversarial checksums or compatibility with legacy systems that require it.
SHA-256 or SHA-512 (both also available on this site) are the current standard choices for cryptographic hashing.
No — hashing happens entirely in your browser using the native Web Crypto API.
