Frequently asked questions
Why include MD5 if it's broken?+
MD5 is needed for legacy systems that still rely on it — software distribution mirrors, old archive verification. Use SHA-256+ for security.
How does it compare to shasum?+
Output matches `shasum -a 256` byte-for-byte. Verify by hashing the same file with both tools.
Can I hash huge files?+
Yes — limited only by your tier's file size limit (5 MB free, 500 MB Pro, 5 GB Developer).
