String decrypter types
none Don't decrypt strings
default Use default string decrypter type (usually static)
static Use static string decrypter if available
delegate Use a delegate to call the real string decrypter
emulate Call real string decrypter and emulate certain instructions
Multiple regexes can be used if separated by '&'.
Use '!' if you want to invert the regex. Example: !^[a-z\d]{1,2}$&!^[A-Z]_\d+$&^[\w.]+$
Examples:
de4dot.exe -r c:\my\files -ro c:\my\output
de4dot.exe file1 file2 file3
de4dot.exe file1 -f file2 -o file2.out -f file3 -o file3.out
de4dot.exe file1 --strtyp delegate --strtok 06000123
