HashData(Byte[])

Source:

SHA1.cs

Computes the hash of data using the SHA1 algorithm.

public:
 static cli::array <System::Byte> ^ HashData(cli::array <System::Byte> ^ source);

public static byte[] HashData (byte[] source);

static member HashData : byte[] -> byte[]

Public Shared Function HashData (source As Byte()) As Byte()

Parameters

source

Byte[]

The data to hash.

Returns

Byte[]

The hash of the data.

Exceptions

ArgumentNullException

source is null.

HashData(Stream)

Source:

SHA1.cs

Computes the hash of a stream using the SHA1 algorithm.

public:
 static cli::array <System::Byte> ^ HashData(System::IO::Stream ^ source);

public static byte[] HashData (System.IO.Stream source);

static member HashData : System.IO.Stream -> byte[]

Public Shared Function HashData (source As Stream) As Byte()

Parameters

source

Stream

The stream to hash.

Returns

Byte[]

The hash of the data.

Exceptions

ArgumentNullException

source is null.

ArgumentException

source does not support reading.

HashData(ReadOnlySpan<Byte>)

Source:

SHA1.cs

Computes the hash of data using the SHA1 algorithm.

public:
 static cli::array <System::Byte> ^ HashData(ReadOnlySpan<System::Byte> source);

public static byte[] HashData (ReadOnlySpan<byte> source);

static member HashData : ReadOnlySpan<byte> -> byte[]

Public Shared Function HashData (source As ReadOnlySpan(Of Byte)) As Byte()

Parameters

source

ReadOnlySpan<Byte>

The data to hash.

Returns

Byte[]

The hash of the data.

HashData(Stream, Span<Byte>)

Source:

SHA1.cs

Computes the hash of a stream using the SHA1 algorithm.

public:
 static int HashData(System::IO::Stream ^ source, Span<System::Byte> destination);

public static int HashData (System.IO.Stream source, Span<byte> destination);

static member HashData : System.IO.Stream * Span<byte> -> int

Public Shared Function HashData (source As Stream, destination As Span(Of Byte)) As Integer

Parameters

source

Stream

The stream to hash.

destination

Span<Byte>

The buffer to receive the hash value.

Returns

Int32

The total number of bytes written to destination.

Exceptions

ArgumentNullException

source is null.

ArgumentException

The buffer in destination is too small to hold the calculated hash size. The SHA1 algorithm always produces a 160-bit hash, or 20 bytes.

-or-

source does not support reading.

HashData(ReadOnlySpan<Byte>, Span<Byte>)

Source:

SHA1.cs

Computes the hash of data using the SHA1 algorithm.

public:
 static int HashData(ReadOnlySpan<System::Byte> source, Span<System::Byte> destination);

public static int HashData (ReadOnlySpan<byte> source, Span<byte> destination);

static member HashData : ReadOnlySpan<byte> * Span<byte> -> int

Public Shared Function HashData (source As ReadOnlySpan(Of Byte), destination As Span(Of Byte)) As Integer

Parameters

source

ReadOnlySpan<Byte>

The data to hash.

destination

Span<Byte>

The buffer to receive the hash value.

Returns

Int32

The total number of bytes written to destination.

Exceptions

ArgumentException

The buffer in destination is too small to hold the calculated hash size. The SHA1 algorithm always produces a 160-bit hash, or 20 bytes.
