HashLume 2.0. EVERYTHING IS FREE EXCEPT THE CERTIFICATE All seven algorithms, folder hashing, verification, manifest import and every export format are now free with no limits. The one paid feature is the Sealed Certificate, $9.99 once. If you already bought the unlock, nothing changes and nothing is taken away: if you bought HashLume Lifetime, you already own the Sealed Certificate. FOLDER DIGESTS YOU CAN REPRODUCE A folder's digest is now computed from a shasum-format manifest, so anyone can recompute its SHA-1 and SHA-2 digests with the tools already on their Mac — and the Sealed Certificate prints the command. The previous method was HashLume's own, in no standard format, and gave two folders the same digest when their files merely traded names. NEW: HASHING, IN PLAIN TERMS A glossary of the words that trip people up, written in ordinary English, in the Help menu. NEW: TRY IT YOURSELF Three things you can run and watch: flip one bit and see half the digest change; check every algorithm against its published test vector; and find a real CRC32 collision live on your own Mac in a few seconds. THE CERTIFICATE, VERIFIABLE BY ANYONE Every certificate now ships with a companion .pem holding the exact signed bytes and the openssl commands to check them, plus a seal over the PDF page itself so the document and the record can be proved to belong together. ACCESSIBILITY A VoiceOver pass: controls named, every table cell spoken with its units, contrast measured on rendered pixels in both appearances, and an in-app Reduce Motion switch.
