Attempts to compute the ECDSA digital signature for the specified read-only span of bytes into the provided destination by using the specified hashing algorithm and the current key.

- data
- ReadOnlySpan<Byte>
The data to be signed.
- hashAlgorithm
- HashAlgorithmName
The algorithm to use to hash the data for signing.
- bytesWritten
- Int32
When this method returns, contains the total number of bytes written into destination. This parameter is treated as uninitialized.
Returns
false if destination is not long enough to receive the signature.
