SHA1Managed Class
Computes the SHA1 hash for the input data using the managed library.
System.Security.Cryptography::HashAlgorithm
System.Security.Cryptography::SHA1
System.Security.Cryptography::SHA1Managed
Assembly: mscorlib (in mscorlib.dll)
The SHA1Managed 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 | Routes data written to the object into the SHA1Managed hash algorithm for computing the hash. (Overrides HashAlgorithm::HashCore(array<Byte>, Int32, Int32).) |
![]() | HashFinal | Returns the computed SHA1 hash value after all data has been written to the object. (Overrides HashAlgorithm::HashFinal().) |
![]() | Initialize | Initializes an instance of SHA1Managed. (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 hash is used as a unique value of fixed size representing a large amount of data. Hashes of two sets of data should match if and only if the corresponding data also matches. Small changes to the data result in large unpredictable changes in the hash.
This is a purely managed implementation of SHA1 that does not wrap CAPI.
The hash size for the SHA1Managed algorithm is 160 bits.
