DSA.HashData Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Computes the hash value of binary data.

Overloads

HashData(Stream, HashAlgorithmName)	When overridden in a derived class, computes the hash value of a specified binary stream by using a specified hashing algorithm.
HashData(Byte[], Int32, Int32, HashAlgorithmName)	When overridden in a derived class, computes the hash value of a specified portion of a byte array by using a specified hashing algorithm.

HashData(Stream, HashAlgorithmName)

Source:

DSA.cs

When overridden in a derived class, computes the hash value of a specified binary stream by using a specified hashing algorithm.

protected:
 virtual cli::array <System::Byte> ^ HashData(System::IO::Stream ^ data, System::Security::Cryptography::HashAlgorithmName hashAlgorithm);

protected virtual byte[] HashData (System.IO.Stream data, System.Security.Cryptography.HashAlgorithmName hashAlgorithm);

abstract member HashData : System.IO.Stream * System.Security.Cryptography.HashAlgorithmName -> byte[]
override this.HashData : System.IO.Stream * System.Security.Cryptography.HashAlgorithmName -> byte[]

Protected Overridable Function HashData (data As Stream, hashAlgorithm As HashAlgorithmName) As Byte()

Parameters

data

Stream

The binary stream to hash.

hashAlgorithm

HashAlgorithmName

The algorithm to use to hash the data.

Returns

Byte[]

The hashed data.

Exceptions

NotImplementedException

A derived class must override this method.

HashData(Byte[], Int32, Int32, HashAlgorithmName)

Source:

DSA.cs

When overridden in a derived class, computes the hash value of a specified portion of a byte array by using a specified hashing algorithm.

protected:
 virtual cli::array <System::Byte> ^ HashData(cli::array <System::Byte> ^ data, int offset, int count, System::Security::Cryptography::HashAlgorithmName hashAlgorithm);

protected virtual byte[] HashData (byte[] data, int offset, int count, System.Security.Cryptography.HashAlgorithmName hashAlgorithm);

abstract member HashData : byte[] * int * int * System.Security.Cryptography.HashAlgorithmName -> byte[]
override this.HashData : byte[] * int * int * System.Security.Cryptography.HashAlgorithmName -> byte[]

Protected Overridable Function HashData (data As Byte(), offset As Integer, count As Integer, hashAlgorithm As HashAlgorithmName) As Byte()

Parameters

data

Byte[]

The data to be hashed.

offset

Int32

The index of the first byte in data that is to be hashed.

count

Int32

The number of bytes to hash.

hashAlgorithm

HashAlgorithmName

The algorithm to use to hash the data.

Returns

Byte[]

The hashed data.

Exceptions

NotImplementedException

A derived class must override this method.
