Starting with an mTLS certificate

Issue of certificates

In any case, you need to download the archive with certificates. You can do this by going to Settings/Application Certificates tab.

The following files will be inside:

.cert - Certificate, encrypted in base64
.csr - Certificate request
.key - Key, encrypted in base64
.p12 - The Certificate & Key bundle, encrypted in PKCS#12

Using the built-in certificate

Move the .p12 file to the project

Generation of your .p12 certificate

To do this, you will need a key(.key) and certificate(.cert) file, download them
Generate .p12 with openSSL
openssl pkcs12 -legacy -export -out certificate.p12 -inkey key.key -in cert.cert
Move the .p12 file to the project

Using certificates for multiplatform application initialization

OneEntryApp.initialize(
   host = "sample.oneentry.cloud",
   path = "path/to/certificate.p12",
   password = "password"
)

Using certificates for Swift application initialization

try OneEntryCore.shared.initialize(
    host: "sample.oneentry.cloud",
    certificate: "certificate",
    password: "password",
    bundle: .module
)
