How to Import PFX Certificates on RealWear Devices

Issue:

There is a known bug in Android that prevents RealWear headsets from importing certain PFX certificates, resulting in a "wrong password" error, even when the correct password is used.

Solution:

Android does not support importing newer PKCS12 files directly. To work around this, you need to convert your certificate to a legacy encryption format, which RealWear headsets can import successfully.

Steps:

1. Generate your PFX certificate for your WiFi network as usual.
2. Convert the certificate using OpenSSL:
   • Open Terminal.
   • Convert your PFX certificate to a PEM file:

openssl pkcs12 -nodes -in certificate.pfx -out output_certificate.pem

• Convert the PEM file back to a PFX file using legacy encryption:

openssl pkcs12 -keypbe PBE-SHA1-3DES -certpbe PBE-SHA1-3DES -export -in output_certificate.pem -out new_certificate.pfx -name "new-certificate"

• If you need to set a password for your certificate, you will have options to enter it during the process.

Following these steps will allow you to successfully import your PFX certificate on RealWear devices.
