+          Description: .NET deobfuscator and unpacker
+           de4dot is a .NET deobfuscator and unpacker. It will try its best to
+           restore a packed and obfuscated assembly to almost the original
+           assembly.
+           .
+           Most of the obfuscation can be completely restored (e.g., string
+           encryption), but symbol renaming is impossible to restore since the
+           original names aren't (usually) part of the obfuscated assembly.
