Migration Guide

Upgrading to v1.0.0

Version 1.0.0 introduces breaking changes that follow from NoNoncense 1.0.0 breaking changes. Be sure to read its migration guide.

You only have to change anything if you are using encrypted IDs.

In order to migrate to NoNoncense 1.x encrypted nonces without breaking its uniqueness guarantees, you MUST NOT change your key or cipher:

pass your existing encryption key to NoNoncense.init/1 new :key64 option
pass :des3 to NoNoncense.init/1 new :cipher64 option

# in application.ex (probably)
NoNoncense.init(
  name: Once,
  machine_id: NoNoncense.MachineId.id!(opts),
  cipher64: :des3,
  key64: System.get_env("ONCE_KEY")
)
