Deckware takes a shuffled deck of 54 cards in your hands (the standard 52-card deck plus 2 distinguishable jokers), and extracts 237-bits of entropy as a hexadecimal string from that shuffle. If sufficiently shuffled, a deck of 54 cards produces ~237.0638 bits of entropy which is strong enough for cryptographic symmetric keys.
The hexadecimal result could be converted into a Niceware passphrase or used as the entropy for a Bitcoin BIP39 mnemonic. Deckware can also directly generate an 8-word passphrase with 79-bits security. Check out this passphrase generator tool.
