Fields

HashSizeInBits	The hash size produced by the SHA256 algorithm, in bits. (Inherited from SHA256)
HashSizeInBytes	The hash size produced by the SHA256 algorithm, in bytes. (Inherited from SHA256)
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)

Properties

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)

Methods

Clear()	Releases all resources used by the HashAlgorithm class. (Inherited from HashAlgorithm)
ComputeHash(Byte[], Int32, Int32)	Computes the hash value for the specified region of the specified byte array. (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)
ComputeHashAsync(Stream, CancellationToken)	Asynchronously computes the hash value for the specified Stream object. (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)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
HashCore(Byte[], Int32, Int32)	When overridden in a derived class, routes data written to the object into the hash algorithm for computing the hash. (Inherited from HashAlgorithm)
HashCore(ReadOnlySpan<Byte>)	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 hash algorithm. (Inherited from HashAlgorithm)
Initialize()	Initializes, or reinitializes, an instance of a hash algorithm.
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(Byte[], Int32, Int32, Byte[], Int32)	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(Byte[], Int32, Int32)	Computes the hash value for the specified region of the specified byte array. (Inherited from HashAlgorithm)
TryComputeHash(ReadOnlySpan<Byte>, Span<Byte>, Int32)	Attempts to compute the hash value for the specified byte array. (Inherited from HashAlgorithm)
TryHashFinal(Span<Byte>, Int32)	Attempts to finalize the hash computation after the last data is processed by the hash algorithm. (Inherited from HashAlgorithm)
