Sqids (pronounced "squids") is an open-source library that lets you generate YouTube-looking IDs from numbers. These IDs are short, can be generated from a custom alphabet and are guaranteed to be collision-free. Read more .
This is what they look like:
Scala code is located at https://github.com/sqids/sqids-scala
To encode & decode:
val sqids = Sqids.default
val id = sqids.encodeUnsafeString(1, 2, 3) // "86Rf07"
val numbers = sqids.decode(id) // List(1, 2, 3)Randomize IDs by providing a custom alphabet:
Alphabet("FxnXM1kBN6cuhsAvjW3Co7l2RePyY8DwaU04Tzt9fHQrqSVKdpimLGIJOgb5ZE")
.flatMap(Sqids.forAlphabet)
.foreach { sqids =>
val id = sqids.encodeUnsafeString(1, 2, 3) // "B4aajs"
val numbers = sqids.decode(id) // List(1, 2, 3)
}Enforce a minimum length for IDs:
Sqids
.withMinLength(10)
.foreach { sqids =>
val id = sqids.encodeUnsafeString(1, 2, 3) // "86Rf07xd4z"
val numbers = sqids.decode(id) // List(1, 2, 3)

The main use of Sqids is purely visual. If you'd like to use IDs instead of numbers in your webapp, Sqids could be a good choice:
