SHA1Cng Class
Provides a Cryptography Next Generation (CNG) implementation of the Secure Hash Algorithm (SHA).
System.Security.Cryptography::HashAlgorithm
System.Security.Cryptography::SHA1
System.Security.Cryptography::SHA1Cng
Assembly: System.Core (in System.Core.dll)
The SHA1Cng type exposes the following members.
| 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, or re-initializes, the instance of the hash algorithm. (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.) |
This algorithm is for hashing only and does not provide any encryption or decryption. It uses the BCrypt (BestCrypt) layer CNG.

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: MayLeakOnAbort. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes. |
Windows 7, Windows Vista SP1 or later, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
