The key material The key material is a random sequence of bytes used to derive a cryptographic key.
Optional
region?: RegionRegion to target. If none is passed will use default region from the config.
Optional
salt?: stringA salt is random data added to key material to ensure unique derived keys, even if the input is similar. It helps strengthen security when the key material has low randomness (low entropy).
The key's origin must be
