this function; however, if the RNG is defined it will improve resistance to side-channel
|
||||
attacks.
|
||||
|
||||
Usage: Compute a hash of the data you wish to sign (SHA-2 is recommended) and pass it to
|
||||
this function along with your private key and a hash context. Note that the message_hash
|
||||
does not need to be computed with the same hash function used by hash_context.
|
||||
|
||||
Inputs:
|
||||
private_key - Your private key.
|
||||
message_hash - The hash of the message to sign.
|
||||
hash_size - The size of message_hash in bytes.
|
||||
hash_context - A hash context to use.
|
||||
|
||||
Outputs:
|
||||
signature - Will be filled in with the signature value.
|
||||
|
||||
Returns 1 if the signature generated successfully, 0 if an error occurred.
