Microsoft Silverlight will reach end of support after October 2021. Learn more.

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)

Syntax

'Declaration
<SecuritySafeCriticalAttribute> _
Public Function SignData ( _
    buffer As Byte(), _
    halg As Object _

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

Parameters

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

Return Value

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

Exceptions

Exception Condition
ArgumentNullException

The halg parameter is nulla null reference (Nothing in Visual Basic).
ArgumentException

The halg parameter is not a valid type.

Remarks

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