RSA.HashData Method

Definition

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.

Parameters

data
Stream

The binary stream to hash.

hashAlgorithm

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

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 in hash the data.

Returns

Byte[]

The hashed data.
