HashingTransformer

class HashingTransformer(val hasher: Hasher) : ColumnTransformer<String, Hashed>

Transformer that stores the Hashed.encodedValue of a hashed value in a character column, using the provided hasher to verify the values read back out of it.

The hashing itself is performed by Hasher.hash, not by this transformer, so a value that is already stored is never hashed again when it is read and written back.
