ECDSASigner class

Implemented types

• Signer

Constructors

ECDSASigner([Digest? _digest, Mac? _kMac])

If _digest is not null it is used to hash the message before signing and verifying, otherwise, the message needs to be hashed by the user of this ECDSASigner object. If _kMac is not null, RFC 6979 is used for k calculation with the given Mac. Keep in mind that, to comply with RFC 69679, _kMac must be HMAC with the same digest used to hash the message.
