Crypto-pro-provider

The library provides methods for signing xml of requests for SMEV2 and SMEV3

Usage

• Import module;

import {
  certificates,
  sign,
  detachedSign,
} from 'crypto-pro-provider';

• First, you need to select certificate. For it use method certificates;

  certificates()
    .then((certificates) => {
      // list of certificates
    })
    .catch((error) => {
      // error
    });

Signature for SMEV 2:

• Sign your message;

  // thumbprint - hash of the before selected certificate
  // base64 - message encoded to base64
  sign(thumbprint, base64)
    .then((signature) => {
      // signed message
    })
    .catch((error) => {
      // error
    });

Signature for SMEV 3:

Signing message for SMEV 3 is more difficult, than for SMEV 2, so you should have server-side for some operations.

Before signing your message by crypto-pro-provider, you should does several actions.

• Sign your message by crypto server;
• From received signature take node SignedInfo;
• Canonicalize SignedInfo (http://www.w3.org/2001/10/xml-exc-c14n#);

Then canonicalized node send to client-side and sign by crypto-pro-provider:

  // thumbprint - hash of the before selected certificate
  // base64 - message encoded to base64
  // signatureTemplateAsBase64 - signature template encoded to base64
  detachedSign(thumbprint, base64, signatureTemplateAsBase64)
    .then((base64) => {
      // Signed XML as base64
    })
    .catch((error) => {
      // error
    });

Save signature.

That's all!
