IncrementalHash.CreateHMAC Method

Definition

Overloads

CreateHMAC(HashAlgorithmName, Byte[])

Create an IncrementalHash for the Hash-based Message Authentication Code (HMAC) algorithm utilizing the hash algorithm specified by hashAlgorithm, and a key specified by key.

CreateHMAC(HashAlgorithmName, ReadOnlySpan<Byte>)

Create an IncrementalHash for the Hash-based Message Authentication Code (HMAC) algorithm utilizing the hash algorithm specified by hashAlgorithm, and a key specified by key.

Create an IncrementalHash for the Hash-based Message Authentication Code (HMAC) algorithm utilizing the hash algorithm specified by hashAlgorithm, and a key specified by key.

public:
 static System::Security::Cryptography::IncrementalHash ^ CreateHMAC(System::Security::Cryptography::HashAlgorithmName hashAlgorithm, cli::array <System::Byte> ^ key);
[System.Runtime.Versioning.UnsupportedOSPlatform("browser")]
public static System.Security.Cryptography.IncrementalHash CreateHMAC (System.Security.Cryptography.HashAlgorithmName hashAlgorithm, byte[] key);
public static System.Security.Cryptography.IncrementalHash CreateHMAC (System.Security.Cryptography.HashAlgorithmName hashAlgorithm, byte[] key);
[<System.Runtime.Versioning.UnsupportedOSPlatform("browser")>]
static member CreateHMAC : System.Security.Cryptography.HashAlgorithmName * byte[] -> System.Security.Cryptography.IncrementalHash
static member CreateHMAC : System.Security.Cryptography.HashAlgorithmName * byte[] -> System.Security.Cryptography.IncrementalHash
Public Shared Function CreateHMAC (hashAlgorithm As HashAlgorithmName, key As Byte()) As IncrementalHash

Parameters

hashAlgorithm
HashAlgorithmName

The name of the hash algorithm to perform within the HMAC.

key
Byte[]

The secret key for the HMAC. The key can be any length, but a key longer than the output size of the hash algorithm specified by hashAlgorithm will be hashed (using the algorithm specified by hashAlgorithm) to derive a correctly-sized key. Therefore, the recommended size of the secret key is the output size of the hash specified by hashAlgorithm.

Returns

An IncrementalHash instance ready to compute the hash algorithm specified by hashAlgorithm.

Attributes

Exceptions

key is null.

hashAlgorithm.Name is null, or the empty string.

hashAlgorithm is not a known hash algorithm.
