Computes the hash value of the specified byte array using the specified hash algorithm and signs the resulting hash value. |
| SignData(Stream, HashAlgorithmName) |
Computes the hash value of the specified stream using the specified hash algorithm and signs the resulting hash value. |
SignData(Byte[], Int32, Int32, HashAlgorithmName)
Computes the hash value of a portion of the specified byte array using the specified hash algorithm and signs the resulting hash value.

override this.SignData : byte[] * int * int * System.Security.Cryptography.HashAlgorithmName -> byte[]Public Overridable Function SignData (data As Byte(), offset As Integer, count As Integer, hashAlgorithm As HashAlgorithmName) As Byte()Parameters
- data
- Byte[]
The input data for which to compute the hash.
- offset
- Int32
The offset into the array at which to begin using data.
- count
- Int32
The number of bytes in the array to use as data.
- hashAlgorithm
- HashAlgorithmName
The hash algorithm to use to create the hash value.
Returns
The DSA signature for the specified data.
Exceptions
data is null.
offset is less than zero.
-or-
count is less than zero.
-or-
offset + count - 1 results in an index that is beyond the upper bound of data.
Applies to
