I thought UUIDs had to be 128 bits, such as "de305d54-75b4-431b-adb2-eb6b9e546014" (32 x 4-bit characters, not counting hypens). How is "ajLWxEodc6CmQLHADuKVwD"

- hesdeadjim 11y ago"de305d54-75b4-431b-adb2-eb6b9e546014" is simply an encoding of a 128 bit number. This standard hex UUID representation requires 8 bits/character * 36 characters == 288 bytes == 2304 bits. This encoding only requires 22 characters or 1408 bytes, almost half the size.
