Transport Layer Security (TLS) is a protocol that provides privacy and data integrity between two communicating applications. Esri is planning to require TLS 1.2 connections for ArcGIS Online services in February 2019. Keep an eye on this Technical Support information page for updates on this.
At that time, ArcPad running on platforms that support TLS 1.2, will continue to work with no limitations or change in behavior.
ArcPad running on platforms that do not support TLS 1.2, will experience the following limitations:
- feature services can not be synced with ArcGIS Online
- ArcPad packages can not be downloaded or uploaded to ArcGIS Online (including the download of ArcPad templates)
All other features will continue to work as normal.
Windows Desktop does support TLS 1.2.
Windows Mobile/CE 6.5 and earlier do not support TLS 1.2. Windows CE 7.0 can be updated to support TLS 1.2, by the manufacturer.
This change has the same consequences on ArcPad users as that experienced in December 2015 due to the SHA2 update.
