UltraLite client applications of MobiLink must be configured to use enable TLS synchronization. Transport-layer security enables encryption, tamper detection, and certificate-based authentication. See Introduction to transport-layer security.

To set up TLS synchronization on an UltraLite client application and device

1. Enable encrypted synchronization by calling one of the following in your application code:

   • To enable RSA encryption, call ULEnableRsaSyncEncryption. See ULEnableRsaSyncEncryption function.

   • To enable ECC encryption, call ULEnableEccSyncEncryption. See ULEnableEccSyncEncryption function.

   • To enable FIPS RSA encryption, call ULEnableRsaFipsSyncEncryption. This function is only required for Palm OS clients. See ULEnableRsaFipsSyncEncryption function.

2. Set the synchronization information stream to either TLS or HTTPS.

3. If you are enabling ECC or FIPS encryption, you also need to:

   • ECC   Set the tls_type network protocol option to ECC. See tls_type.

   • FIPS   Set the fips network protocol option to Yes. See fips.

4. Ensure that you have linked to the appropriate libraries:

   Platform	Linking	RSA encryption	ECC encryption	FIPS encryption
   Windows desktop	static1	ulrsa.lib	ulecc.lib	none
   Windows desktop	dynamic2	none	none	none
   Windows Mobile	static1	ulrsa.lib	ulecc.lib	none
   Windows Mobile	dynamic 2	none	none	none
   Palm OS	static1	ulrsa.lib	ulecc.lib	ulfips.lib, gse1st.lib

   ¹ You must also link to ulrt.lib.

   ² You must also link to ulimp.lib.

5. Ensure that the appropriate files are copied to the device:

   Platform	Linking	RSA encryption	ECC encryption	FIPS encryption
   Windows desktop	static	none	none	mlcrsafips11.dll sbgse2.dll
   Windows desktop	dynamic1	mlcrsa11.dll	mlcecc11.dll	mlcrsafips11.dll sbgse2.dll
   Windows Mobile	static	none	none	mlcrsafips11.dll sbgse2.dll
   Windows Mobile	dynamic1	mlcrsa11.dll	mlcecc11.dll	mlcrsafips11.dll sbgse2.dll
   Palm OS	static	none	none	libsbgse_4i.prc
   Windows Mobile components and UltraLite engine	static2	mlcrsa11.dll	mlcecc11.dll	mlcrsafips11.dll sbgse2.dll

   ¹ You must also deploy ulrt11.dll.

   ² You must also deploy your component .dll file and/or uleng11.exe.
