Methods
# createGaloisKeys(stepsopt) → {GaloisKeys}
Generates and returns Galois keys. This function returns Galois keys in
a fully expanded form and is meant to be used primarily for demo, testing,
and debugging purposes. The user can optionally give an input a vector of desired
Galois rotation step counts, where negative step counts correspond to
rotations to the right and positive step counts correspond to rotations to
the left. A step count of zero can be used to indicate a column rotation
in the BFV scheme complex conjugation in the CKKS scheme.
Parameters:
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
steps |
Int32Array
|
<optional> |
Int32Array.from([]) | Specific Galois Elements to generate |
New GaloisKeys from the KeyGenerator's internal secret key
# createGaloisKeysSerializable(stepsopt) → {Serializable.<GaloisKeys>}
Generates and returns Galois keys as a serializable object. This function
creates specific Galois keys that can be used to apply specific Galois
automorphisms on encrypted data. The user can optionally give an input a vector
of desired Galois rotation step counts, where negative step counts
correspond to rotations to the right and positive step counts correspond
to rotations to the left. A step count of zero can be used to indicate
a column rotation in the BFV scheme complex conjugation in the CKKS scheme.
Half of the key data is pseudo-randomly generated from a seed to reduce
the object size. The resulting serializable object cannot be used
directly and is meant to be serialized for the size reduction to have an
impact.
Parameters:
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
steps |
Int32Array
|
<optional> |
Int32Array.from([]) | Specific Galois Elements to generate |
Base64 encoded string
# createPublicKeySerializable() → {Serializable.<PublicKey>}
Create a new, Serializable PublicKey instance
A new, serializable, PublicKey instance
# createRelinKeys() → {RelinKeys}
Generates and returns relinearization keys. This function returns
relinearization keys in a fully expanded form and is meant to be used
primarily for demo, testing, and debugging purposes.
New RelinKeys from the KeyGenerator's internal secret key
# createRelinKeysSerializable() → {Serializable.<RelinKeys>}
Generates and returns relinearization keys as a serializable object.
Half of the key data is pseudo-randomly generated from a seed to reduce
the object size. The resulting serializable object cannot be used
directly and is meant to be serialized for the size reduction to have an
impact.
New, serializable RelinKeys from the KeyGenerator's internal secret key
# delete()
Delete the underlying WASM instance.
Should be called before dereferencing this object to prevent the
WASM heap from growing indefinitely.
