Hello, everyone
Checking internet I combine everything and found my own solution
It takes 5 minutes and do not need any script to compile
1. transfer package ownership to my domain account
2. transfer job to my account
3. execute dtsrun DTSRun /~Z0x5...... with switches /!X /!C from my machine
It gave you decrypted line with parameter /M "password"
When I was trying to do this on server it did not give /M parameter, only from my machine
Thanks to everybody for help
