withPRFAndR
public FipsKDF.CounterModeParametersBuilder withPRFAndR(FipsKDF.PRF prf, int r)
Return a new parameters builder based around the passed in PRF and counter size.- Parameters:
prf
- the PRF to be used in the final KDF.r
- the length in bits of the counter to be used.- Returns:
- a new parameters builder.
-
using
public FipsKDF.CounterModeParameters using(byte[] ki, byte[] fixedInputPrefix)
Return a new parameter set for ki and a prefix.- Parameters:
ki
- derivation key for the KDF.fixedInputPrefix
- prefix data to come before the counter during calculation.- Returns:
- a CounterModeParameters object.
-
using
public FipsKDF.CounterModeParameters using(byte[] ki, byte[] fixedInputPrefix, byte[] fixedInputSuffix)
Return a new parameter set for ki and the prefix/suffix data.- Parameters:
ki
- derivation key for the KDF.fixedInputPrefix
- prefix data to come before the counter during calculation.fixedInputSuffix
- suffix data to come after the counter during calculation.- Returns:
- a CounterModeParameters object.
-
using
public FipsKDF.CounterModeParameters using(byte[] ki, boolean isPrefix, 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.isPrefix
- is the fixed input a prefix or a suffix.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 CounterModeParameters object.
