Hashids.java

• Hashids: Generate short unique ids from integers

• Auto Generate Sequential UIID

  You basically want Hashids but sequential? Why not simple convert a base 10 (0-9) number to hex? (0-F)

  I found hashids [1] to be a great compromise between integer ids in the database and copyable non-enumerable strings on the client.

• Short, friendly base32 slugs from timestamps

• We Chose NanoIDs for PlanetScale’s API

  I wonder how this might compare to just storing regular autoincrementing ints in the database, and converting to/from hashids (https://hashids.org/) at the edge. It eliminates the collision concern and stores more compactly at the cost of a tiny amount of encode/decode when processing requests. You’d want to push it down as close to the database layer as possible to avoid inadvertent int ID leaks; I added native hashids support to clickhouse but I’m not sure what other database support might entail.

• How can I generate truly unique slugs?

  Since hashids are not really hashes and are not secure at all this is not even achieved. Hashids can be easily decoded without the salt by a simple brute-force attack described by the authors of hashid themselves right on their website: https://hashids.org/

• How to handle id-based routes with UUID
  1 project | /r/learnprogramming | 14 Dec 2022

  You don't necessarily need to use UUIDs. You could use something like Hashids to generate random strings from your sequential IDs in a reversible way, so that users can't predict what their values will be, but you can decode them as needed.

• All of my database models have id replaced with UUID4s. Is there any risk to using these in URLs?
  1 project | /r/djangolearning | 25 Aug 2022

  You should not use UUIDv4 as a primary key. You can use normal int values and then use hashids to make them safe for URL. UUIDv7 might be good to use as well once they are more widely supported as well.

• What’s Django’s argument for using 64-bit int as default pk over uuid. Can anyone point me to something I can read?
