Adds WPA3-SAE PAKE algorithm implementation for CRACEN. Note: While this commit contains the algorithm implementation, it does not provide implementation for the KDF required by the H2E and GDH algorithm variations. Missing functionality is provided by Oberon, so both Oberon and Cracen drivers must be activated. Ref: NCSDK-29191 Signed-off-by: Anton Zyma <anton.zyma@nordicsemi.no>
Added implementation of the SSWU (Simplified Shallue-Woestijne-Ulas) deterministic hash-to-element method. This is required to derive an element of an ECC group (point on the curve) from hash. The algorithm is aimed to be used for PT secret element creation needed by WPA3-SAE. Ref: NCSDK-29191 Signed-off-by: Anton Zyma <anton.zyma@nordicsemi.no>
The KDF is used to obtain password token (PT) which is then used by the H2E or GDH algorithm variation to calculate password element (PWE). Ref: NCSDK-29191 Signed-off-by: Anton Zyma <anton.zyma@nordicsemi.no>
Added the ability to import the Password Token key that can be used for WPA3-SAE. Ref: NCSDK-29191 Signed-off-by: Anton Zyma <anton.zyma@nordicsemi.no>
