- hashAlgorithm
- HashAlgorithmName
The algorithm used to compute the HMAC.
- key
- ReadOnlySpan<Byte>
The secret key. The key can be any length.
- source
- ReadOnlySpan<Byte>
The data to compute the HMAC over.
- bytesWritten
- Int32
When this method returns, the total number of bytes written into destination.
Returns
false if destination is too small to hold the calculated HMAC, true otherwise.
Exceptions
hashAlgorithm has a Name that is empty.
hashAlgorithm has a Name that is
null.
hashAlgorithm specifies a hash algorithm not supported by the current platform.
hashAlgorithm specifies an unknown hash algorithm.
