What kind of encryption method will encrypt javascript above?

网友答案:

The first bit of "encryption" appears to be hex ASCII codes:

\x63\x6f\x6e\x73\x74\x72\x75\x63\x74\x6f\x72

becomes

constructor

Try man ascii for the decryption key.

The second bit of "encryption" also appears to be hex ASCII codes:

%69%66%28%7e%6c%6f%63%61%74%69%6f%6e...

becomes

if(~location...
