SHA1CryptoServiceProvider Class
Computes the SHA1 hash value for the input data using the implementation provided by the cryptographic service provider (CSP). This class cannot be inherited.
System.Security.Cryptography.HashAlgorithm
System.Security.Cryptography.SHA1
System.Security.Cryptography.SHA1CryptoServiceProvider
Namespace: System.Security.Cryptography
Assembly: mscorlib (in mscorlib.dll)
The SHA1CryptoServiceProvider type exposes the following members.
| Name | Description | |
|---|---|---|
 | SHA1CryptoServiceProvider | Initializes a new instance of the SHA1CryptoServiceProvider class. |
| Name | Description | |
|---|---|---|
| CanReuseTransform | Gets a value indicating whether the current transform can be reused. (Inherited from HashAlgorithm.) |
| CanTransformMultipleBlocks | When overridden in a derived class, gets a value indicating whether multiple blocks can be transformed. (Inherited from HashAlgorithm.) |
| Hash | Gets the value of the computed hash code. (Inherited from HashAlgorithm.) |
| HashSize | Gets the size, in bits, of the computed hash code. (Inherited from HashAlgorithm.) |
| InputBlockSize | When overridden in a derived class, gets the input block size. (Inherited from HashAlgorithm.) |
| OutputBlockSize | When overridden in a derived class, gets the output block size. (Inherited from HashAlgorithm.) |
| Name | Description | |
|---|---|---|
| Clear | Releases all resources used by the HashAlgorithm class. (Inherited from HashAlgorithm.) |
| ComputeHash(Byte[]) | Computes the hash value for the specified byte array. (Inherited from HashAlgorithm.) |
| ComputeHash(Stream) | Computes the hash value for the specified Stream object. (Inherited from HashAlgorithm.) |
| ComputeHash(Byte[], Int32, Int32) | Computes the hash value for the specified region of the specified byte array. (Inherited from HashAlgorithm.) |
| Dispose() | Releases all resources used by the current instance of the HashAlgorithm class. (Inherited from HashAlgorithm.) |
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| Initialize | Initializes an instance of SHA1CryptoServiceProvider. (Overrides HashAlgorithm.Initialize().) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| TransformBlock | Computes the hash value for the specified region of the input byte array and copies the specified region of the input byte array to the specified region of the output byte array. (Inherited from HashAlgorithm.) |
| TransformFinalBlock | Computes the hash value for the specified region of the specified byte array. (Inherited from HashAlgorithm.) |
| Name | Description | |
|---|---|---|
| HashValue | Represents the value of the computed hash code. (Inherited from HashAlgorithm.) |
The following code example computes the SHA1 hash value for data and stores it in result. This example assumes that there is a predefined constant DATA_SIZE.
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
