ECDSA — How to programmatically sign a transaction

WebRemarks. If you develop your own implementation of an ECDsa object, you can use the Create (String) method overload to create a custom algorithm string that specifies your implementation. If you specify a custom value for the algorithm parameter, the CryptoConfig object will use it to determine whether an ECDSA object can be created.

WebJan 23, 2024 · ECDSA is a signature algorithm derived from ECC (elliptic curve cryptography). So in a way encryption even "came first". Asymmetric encryption is very inperformant though. You could in principle use common schemes like Cipher-Block-Chaining (CBC) to encrypt large files asymmetrically, but the gains do not justify the means. WebThe algorithm name.
