Frequently asked questions
Which hash algorithm should I use?
SHA-256 is the standard general-purpose choice for integrity checks. SHA-1 is considered cryptographically broken and should only be used for non-security purposes like cache keys.
Can this generate MD5 hashes?
No. Browsers' native Web Crypto API doesn't expose MD5 since it's deprecated for security use — this tool sticks to the SHA family, which is natively supported and safe to rely on.
