Use P12imprt to import a Personal Certificate from a PKCS#12 file.
Windows Mobile requires a Personal Certificate for:
- L2TP/IPsec VPNs.
- Web client authentication.
- EAP-TLS wireless networks.
Personal Certificates are often distributed in a PKCS#12 file with the extension .p12 or .pfx.
Windows Mobile does not support PKCS#12 files, unlike desktop Windows. But with P12imprt you can import them on your Windows Mobile device.
