Windows.Security.Cryptography.Core.KeyDerivationParameters.BuildForSP80056a

-description

Creates a KeyDerivationParameters object for use in the SP800-56A key derivation function.

-parameters

-param algorithmId

Specifies the intended purpose of the derived key.

-param partyUInfo

Contains public information contributed by the initiator.

-param partyVInfo

Contains public information contributed by the responder.

-param suppPubInfo

Contains public information known to both initiator and responder.

-param suppPrivInfo

Contains private information known to both initiator and responder, such as a shared secret.

-returns

Refers to the parameters used during key derivation.

-remarks

You can use the following algorithm names with the OpenAlgorithm function to open a SP80056a KDF algorithm provider:

• KeyDerivationAlgorithmNames.Sp80056aConcatMd5
• KeyDerivationAlgorithmNames.Sp80056aConcatSha1
• KeyDerivationAlgorithmNames.Sp80056aConcatSha256
• KeyDerivationAlgorithmNames.Sp80056aConcatSha384
• KeyDerivationAlgorithmNames.Sp80056aConcatSha512
