Using EDS CryptoPRO?

Question

Cryptography

I look at CryptoPro for developers - I see and net is supported.
It is necessary to implement automatic signing of EDS documents. Those. the variant of a manager with a Word with a plug-in is not desirable. What is the easiest way to go?

Answer 1

The easiest way is to buy the cryptcp command line utility, it's not expensive.

Answer 2

In a nutshell, for .NET you need CryptoPro CSP (CryptoProvider) and CryptoPro .NET (provides interaction between .NET and CryptoProvider).
Auto-signing is possible, but requires a private key. Your code (by calling the appropriate CryptoAPI methods) must ensure that the container of the private key is looked up and that the signature is generated and verified. You can specify search options in the configuration, but this implementation is convenient if you use one key that is updated once a year (for example, for server-side signing). For custom signing, it is better to use the user's choice of the desired certificate. For example, using the CryptoPro EDS Browser plug-in , if we talk about signing data through a web interface.
