ECDiffieHellman.DeriveKeyFromHash ECDiffieHellman.DeriveKeyFromHash ECDiffieHellman.DeriveKeyFromHash ECDiffieHellman.DeriveKeyFromHash Method

Definition

Derives bytes that can be used as a key using a hash function .

Overloads

DeriveKeyFromHash(ECDiffieHellmanPublicKey, HashAlgorithmName) DeriveKeyFromHash(ECDiffieHellmanPublicKey, HashAlgorithmName) DeriveKeyFromHash(ECDiffieHellmanPublicKey, HashAlgorithmName) DeriveKeyFromHash(ECDiffieHellmanPublicKey, HashAlgorithmName)

Derives bytes that can be used as a key using a hash function, given another party's public key and hash algorithm's name.

DeriveKeyFromHash(ECDiffieHellmanPublicKey, HashAlgorithmName, Byte[], Byte[]) DeriveKeyFromHash(ECDiffieHellmanPublicKey, HashAlgorithmName, Byte[], Byte[]) DeriveKeyFromHash(ECDiffieHellmanPublicKey, HashAlgorithmName, Byte[], Byte[]) DeriveKeyFromHash(ECDiffieHellmanPublicKey, HashAlgorithmName, Byte[], Byte[])

When implemented in a derived class, derives bytes that can be used as a key using a hash function, given another party's public key, hash algorithm's name, a prepend value and an append value.

Public Function DeriveKeyFromHash (otherPartyPublicKey As ECDiffieHellmanPublicKey, hashAlgorithm As HashAlgorithmName) As Byte()

Parameters

hashAlgorithm
HashAlgorithmName HashAlgorithmName HashAlgorithmName HashAlgorithmName

The hash algorithm to use to derive the key material.

Returns

Byte[]

The key material from the key exchange with the other party's public key.

Exceptions

otherPartyPublicKey is over a different curve than this key.

Remarks

This overload calls the DeriveKeyFromHash method passing null as the prepend and append values.

Parameters

hashAlgorithm
HashAlgorithmName HashAlgorithmName HashAlgorithmName HashAlgorithmName

The hash algorithm to use to derive the key material.

secretPrepend
Byte[]

A value to prepend to the derived secret before hashing.

secretAppend
Byte[]

A value to append to the derived secret before hashing.

Returns

Byte[]

The key material from the key exchange with the other party's public key.

Exceptions

otherPartyPublicKey is over a different curve than this key.
