Sqids (pronounced "squids") is an open-source library that lets you generate short unique identifiers from numbers. These IDs are URL-safe, can encode several numbers, and do not contain common profanity words. Read more .
This is what they look like:
Quick encode & decode example:
val sqids = Sqids.default
val id = sqids.encodeUnsafeString(1, 2, 3) // "86Rf07"
val numbers = sqids.decode(id) // List(1, 2, 3)
If IDs are too short, you can pad them to a certain length:
Sqids
.withMinLength(10)
.foreach { sqids =>
val id = sqids.encodeUnsafeString(1, 2, 3) // "86Rf07xd4z"
val numbers = sqids.decode(id) // List(1, 2, 3)
}
Create unique IDs by shuffling the alphabet:
Alphabet("k3G7QAe51FCsPW92uEOyq4Bg6Sp8YzVTmnU0liwDdHXLajZrfxNhobJIRcMvKt")
.flatMap(Sqids.forAlphabet)
.foreach { sqids =>
val id = sqids.encodeUnsafeString(1, 2, 3) // "XRKUdQ"
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 project, Sqids could be a good choice.
