caikit.core.toolkit.reversible_hasher

The ReversibleHasher provides a simple obfuscation tool for munging strings in a reversible way. It is useful when needing a repeatable way to obfuscate a string that may come from a configuration detail that should not be transparently visible to a user, but needs to be trivially reversed, possibly with entirely new in-memory state.

WARNING: This utility is intentionally not a cryptographically secure hash! It: is explicitly designed to be reversible.
