RSACryptoServiceProvider.SignData Method (Byte[], Object)

Computes the hash value of the specified byte array using the specified hash algorithm, and signs the resulting hash value.

Namespace:  System.Security.Cryptography
Assembly:  mscorlib.Extensions (in mscorlib.Extensions.dll)

public byte[] SignData(
	byte[] buffer,
	Object halg


Type: System.Byte[]
The input data for which to compute the hash.
Type: System.Object
The hash algorithm to use to create the hash value.

Return Value

Type: System.Byte[]
The RSA signature for the specified data.


The halg parameter is null.


The halg parameter is not a valid type.

This method creates a digital signature that is verified using the VerifyData method.

The halg parameter can accept a String, a HashAlgorithm, or a Type.
