B4J Question Encryption works fine in release mode but not in standalone package

[AliFarahbod]

Hi,

Encryption works fine in release mode but not in standalone package.
Every thing is well when I run program as a release mode, but not in Standalone package.
I am using Encryption lib in B4A and B4J and not B4XEncryption.

Runnig "run_debug.bat" result like as bellow:

Any ideas on what I have done wrong ?

 

[Erel]

This code works fine after building a standalone package:

#AdditionalJar: bcprov-jdk15on-154
Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Private xui As XUI 
    Private Button1 As B4XView
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.RootPane.LoadLayout("Layout1")
    MainForm.Show
    Dim x As B4XCipher
    x.Encrypt("test".GetBytes("utf8"), "1234")
End Sub

Try it.

Thank you Erel,

The solution was so simple, just replace "AES/CBC/PKCS7Padding" with "AES/CBC/PKCS5Padding".
