Bug #92428 has been fixed on 10.2.1. In order to fix this bug on an migrated application, Crypto.vb needs to be replaced.
During migration, Crypto.vb is replaced with an updated version for VB.NET applications. For C# applications, this will not be migrated.
After migration, re-apply any customizations you may have made to the original file.
