Properties
AlgorithmName |
Gets the name of the algorithm being performed. HMAC algorithms are prepended with "HMAC" to distinguish them from an unkeyed digest. |
HashLengthInBytes |
Gets the output size of this hash or HMAC algorithm, in bytes. |
Methods
AppendData(Byte[]) |
Appends the specified data to the data already processed in the hash or HMAC. |
AppendData(Byte[], Int32, Int32) |
Appends the specified number of bytes from the specified data, starting at the specified offset, to the data already processed in the hash or Hash-based Message Authentication Code (HMAC). |
AppendData(ReadOnlySpan<Byte>) |
Appends the specified data to the data already processed in the hash or Hash-based Message Authentication Code (HMAC). |
Clone() |
Creates a new instance of IncrementalHash with the existing appended data preserved. |
CreateHash(HashAlgorithmName) |
Creates an IncrementalHash for the specified algorithm. |
CreateHMAC(HashAlgorithmName, Byte[]) |
Creates an IncrementalHash for the Hash-based Message Authentication Code (HMAC) algorithm using the specified hash algorithm and key. |
CreateHMAC(HashAlgorithmName, ReadOnlySpan<Byte>) |
Create an IncrementalHash for the Hash-based Message Authentication Code (HMAC) algorithm utilizing the hash algorithm specified by |
Dispose() |
Releases the resources used by the current instance of the IncrementalHash class. |
Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
GetCurrentHash() |
Retrieves the hash or Hash-based Message Authentication Code (HMAC) for the data accumulated from prior calls to the AppendData(ReadOnlySpan<Byte>) methods, without resetting the object to its initial state. |
GetCurrentHash(Span<Byte>) |
Retrieves the hash or Hash-based Message Authentication Code (HMAC) for the data accumulated from prior calls to the AppendData(ReadOnlySpan<Byte>) methods, without resetting the object to its initial state. |
GetHashAndReset() |
Retrieves the hash or Hash-based Message Authentication Code (HMAC) for the data accumulated from prior calls to the AppendData methods, and resets the object to its initial state. |
GetHashAndReset(Span<Byte>) |
Retrieves the hash or Hash-based Message Authentication Code (HMAC) for the data accumulated from prior calls to the AppendData(ReadOnlySpan<Byte>) methods, and resets the object to its initial state. |
GetHashCode() |
Serves as the default hash function. (Inherited from Object) |
GetType() |
Gets the Type of the current instance. (Inherited from Object) |
MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
ToString() |
Returns a string that represents the current object. (Inherited from Object) |
TryGetCurrentHash(Span<Byte>, Int32) |
Attempts to retrieve the hash or Hash-based Message Authentication Code (HMAC) for the data accumulated from prior calls to the AppendData(ReadOnlySpan<Byte>) methods, without resetting the object to its initial state. |
TryGetHashAndReset(Span<Byte>, Int32) |
Attempts to finalize the hash computation after the last data is processed by the hash algorithm. |
