module for Bitrix24 NCA RK EDS two ways to sign approval sheet with QR EDS register

Signing documents with a Kazakhstan electronic digital signature (EDS) right in your Bitrix24 portal

A document follows the route “initiator → approvers → final approver”, and every step is certified with an EDS issued by the National Certification Authority of Kazakhstan (NCA RK). The output is a PDF with an approval sheet and an entry in the register. Signing can be built into any business process in the portal.

Features

What employees see

Screenshots were taken on a pilot environment. Click a screenshot to enlarge it.

Signing page: PDF preview, approval progress, choice of signing method and the “Sign with EDS” button — **Signing: two methods to choose from**

**NCALayer** — the key never leaves the employee’s computer or storage device

**.p12 key file** — the signature is created on the portal server, with no software to install

You can reject the document right here, with a mandatory reason

Memo card: the “EDS signing” block in the feed on the right, with participants and statuses — **Signing progress — in the document card**

The block sits on the right in the feed, so the card fields don’t shift

You can see who has signed, who has the document now and who is next

If it’s your turn, the “Sign with EDS” button is right here

Reliability

A signature is accepted only after verification with NCA RK

Integrity

Exactly this file was signed — checked by SHA-256

Certificate chain

Up to the NCA RK root certificate

Revocation status

Online check via OCSP or CRL

Timestamp

The NCA RK TSP records the moment of signing

Key type

Signing key only, not AUTH

Owner

The employee’s IIN and the organization’s BIN are matched

Test mode

Any keys are accepted and documents are marked “no legal force” — for pilots and training.

Production mode

Only signatures confirmed by NCA RK. No marks — the document is ready for use.

Requirements of the Republic of Kazakhstan

What the module covers technically

Requirement	How it is implemented
Equivalence to a paper document	NCA RK EDS; the sheet refers to clause 1 of Article 7 of Law No. 370-II
Certificate validity	Chain up to the NCA RK root, revocation check via OCSP / CRL
Moment of signing	NCA RK TSP timestamp in every signature
Document immutability	Immutable copy of the file and SHA-256 hash
Third-party verification	Verification page via QR; the original and the CMS / CAdES signatures can be verified with any NCA RK tool

The electronic document management regulations and the approval sheet form are approved by the organization itself — we recommend reviewing them with your lawyers and records management department.

We’ll show it on your own documents

We’ll set up document types, fields and routes for your processes, switch the module to production mode and train your staff.
