BitLocker does this and it's nice UX for walking someone through a recovery key over the phone.
Another VERY nice feature is it hashes each set of 6 digits as you type, so if you transpose one, you immediately get feedback instead of "invalid key!" after typing the whole thing out.

- Mavvie 3y agoI don't think that's how it works... It's a checksum, not letting you check if each section is part of the key. At worst, the key would have some portion less entropy since there's a lot of bits used for checksums.
