Fields

OutputLength

The output length of the Blake2 hash in bytes.

Declaration

public const int OutputLength = 64

Field Value

Type	Description
System.Int32

Remarks

This is the maximum length buffer a Blake2 hash can produce Blake2 will always hash to this length even when configured to hash to a shorter value - the final step is to truncate the result.

Note, the length of the expected result is hashed into the result so the OutputLength-byte buffer will hold different values depending on the configured output length. Do not run Blake2 using the default length and then truncate and expect to get the same result as if you configured Blake2 to produce a shorter result.

Methods

ComputeHash(Byte[], Blake2BConfig, SecureArrayCall)

Perform a Blake2 hash on the given buffer using the given Blake2 configuration.

Declaration

public static byte[] ComputeHash(byte[] data, Blake2BConfig config, SecureArrayCall secureArrayCall)

Parameters

Type	Name	Description
System.Byte[]	data	The buffer to hash.
Blake2BConfig	config	The configuration to use.
SecureArrayCall	secureArrayCall	The methods that get called to secure arrays. A null value defaults to SecureArray.DefaultCall.
