What this solution does

The module enables signing documents with a qualified electronic signature (QES/UQES) directly within the on-premise version of Bitrix24. Cloud versions of the platform are not supported. Signed files are generated with a visual stamp in PDF format and retain full legal validity under Federal Law No. 63-FZ 'On Electronic Signatures'.

Key use cases:

HR electronic document management (HR EDO) — signing orders, applications, employment contracts, and local regulatory acts with employees.

Partner collaboration — signing contracts, specifications, and acts from CRM cards.

Business process integration — adding a document signing action to the Bitrix24 business process designer to include signing in existing approval workflows.

Signature visualization — embedding a signature stamp with certificate details, text, and a background image, such as a company logo, into the PDF file.

Technical capabilities:

Support for signature types: QES, UQES, and NQES (GOST algorithms).

Compatibility with CAdES formats (detached and attached signatures) and PAdES (signatures embedded in PDF documents).

The module supports signature profiles CAdES-BES, PAdES-BES, PAdES-T, and PAdES-X Long Type 1. Signing is performed locally in the user's browser via the CryptoPro plugin; cryptographic keys are not transmitted to Bitrix24 servers or third-party services.

To operate the module, the following must be installed on user workstations: CryptoPro CSP version 4 or higher, the CryptoPro EDS Browser plug-in, and a valid electronic signature certificate.

If needed, Bitrix24 business processes, including approval workflows with a signing action, can be configured to match company regulations. The module logic can also be customized to meet specific requirements.

The module is available for testing during a trial period. Technical support and consultations are provided with an active license.

General iT can install and configure this module and check how it works on your website.
