SHA1CryptoServiceProvider Class
Visual Studio 2010
Computes the SHA1 hash value for the input data using the implementation provided by the cryptographic service provider (CSP). This class cannot be inherited.

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(array<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(array<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.) |
![]() | Dispose(Boolean) | Releases the unmanaged resources used by the HashAlgorithm and optionally releases the managed resources. (Inherited from HashAlgorithm.) |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (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.) |
![]() | HashCore | When overridden in a derived class, routes data written to the object into the hash algorithm for computing the hash. (Inherited from HashAlgorithm.) |
![]() | HashFinal | When overridden in a derived class, finalizes the hash computation after the last data is processed by the cryptographic stream object. (Inherited from HashAlgorithm.) |
![]() | Initialize | Initializes an instance of SHA1CryptoServiceProvider. (Overrides HashAlgorithm::Initialize().) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | 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 | |
|---|---|---|
![]() | HashSizeValue | Represents the size, in bits, of the computed hash code. (Inherited from HashAlgorithm.) |
![]() | HashValue | Represents the value of the computed hash code. (Inherited from HashAlgorithm.) |
![]() | State | Represents the state of the hash computation. (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.
