.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 (eg. string
 encryption), but symbol renaming is impossible to restore since the
 original names aren't (usually) part of the obfuscated assembly.
