Method Details
-
withPRF
Return a new parameters builder based around the passed in PRF.- Parameters:
prf
- the PRF to be used in the final KDF.- Returns:
- a new parameters builder.
-
withR
Return a new parameters builder based around the passed in counter size. The counter will be after the iteration data.- Parameters:
r
- the length in bits of the counter to be used.- Returns:
- a new parameters builder.
-
withRAndLocation
public FipsKDF.FeedbackModeParametersBuilder withRAndLocation(int r, FipsKDF.CounterLocation counterLocation) Return a new parameters builder based around the passed in counter size and counter position.- Parameters:
r
- the length in bits of the counter to be used.counterLocation
- the location of the counter in data passed to the PRF during calculation.- Returns:
- a new parameters builder.
-
using
Return a new parameter set for ki and a prefix.- Parameters:
ki
- derivation key for the KDF.iv
- the IV to use at the start of the calculation.fixedInputData
- fixed input data to use in calculation.- Returns:
- a FeedbackModeParameters object.
-
using
public FipsKDF.FeedbackModeParameters using(byte[] ki, byte[] iv, byte[] label, byte[] context, int L) Build method for parameters which builds fixed input as outlined in SP 800-108 with the fixed input as a prefix, or suffix, to the counter.- Parameters:
ki
- input key.iv
- initialization vector.label
- label - fixed input component.context
- context - fixed input component.L
- number of bits per request for the KDF these parameters will initialise - fixed input component.- Returns:
- a FeedbackModeParameters object.
