Authentication and Certificates

Introduction

Authentication with the LHV Connect API is done through mutual TLS (mTLS), which has the following prerequisites in our case:

  • A valid customer agreement with LHV

  • A signed additional Connect agreement

  • A private connection certificate

  • Our LHV Connect certificate

The following certificates are required for authentication with the LHV Connect API.

Private Connection Certificate

The Private Connection Certificate is a certificate for the TLS protocol and it is formed as a PEM -encoded Certificate file with an associated PEM-encoded key. An example is below.

Purpose

The connection certificate identifies and confirms on the transport layer that messages were sent by a known customer's integration.

Creation

  1. LHV sends the customer necessary instructions for generating the certificate request file (request.csr) and certificate key. Only the customer itself is the owner of the key and responsible for storing it securely.

  2. Customer sends the request file to Connect support team at connect@lhv.com

  3. Our support team sends back the actual certificate. \

Public Root Certificate for connect.lhv.com

The Public Root Certificate gives the customer the security that they are communicating with the correct service. We use DigiCert as the root CA.

Our current Connect host root certificate is DigiCert Global Root G2:
