I later extracted those and decrypted them (3ds max's encryption algorithm is terrible). It's actualy a zip file with a bunch of maxcripts in. If you need to convert strings to bytes array : algorithm.key = (DotnetObject '8Encoding').GetBytes '32chars'Īlgorithm.IV = (DotnetObject '8Encoding').GetBytes '16chars'įinal code : fn encryptText plainText tKey: tIV: =Īlgorithm.key = (DotnetObject '8Encoding').GetBytes tKeyĪlgorithm.IV = (DotnetObject '8Encoding').GetBytes tIVĬStreamTransform = algorithm.CreateEncryptor algorithm.key algorithm.IVĮncryptText 'test' tKey:'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa' tIV:'bbbbbbbbbbbbbbbb'ĬStream = dotnetObject '' memStream cStreamTransform cStreamMode.Yesterday I took some time to look into the Sc2 Art Tools files, I then noticed a file called SC2ArtTools.mzp. MemStream = dotnetObject 'System.IO.MemoryStream'ĬStreamMode = (dotnetClass '')ĬStreamTransform = algorithm.CreateEncryptor tKey tIVĬStream = dotnetObject '' memStream cStreamTransform cStreamMode.WriteĪs I’ve said ,I tried too many times ,but failed.Īre you sure that your key and IV are bytes array and not strings ?īecause appart from that it works If I use the default key and IV from the algorithm creation : cStreamTransform = algorithm.CreateEncryptor algorithm.key algorithm.IV Thanks,actually there has a similar maxscript for encryption and decrytion :ĭnUTF8 = dotNetObject '8Encoding'Īlgorithm = (dotnetClass '').Create() Would become in Maxscript (DotnetClass '8Encoding').UTF8.GetString(decbuff) Net api in maxsciprt using some keywords : max doc about dotNet Or does anyone has a better suggestion or solution of encryption/decryption between php and maxscript,thanks. String temp = DecryptRJ256(Server.UrlDecode(Decode(cypher)), keyString, ivString) Using (StreamReader sr = new StreamReader(cs)) Using (CryptoStream cs = new CryptoStream(ms, rj.CreateDecryptor(Key, IV), CryptoStreamMode.Read)) MemoryStream ms = new MemoryStream(message) byte message = Convert.FromBase64String(cypher) īyte message = encoding.GetBytes(cypher) īyte Key = encoding.GetBytes(KeyString) UTF8Encoding encoding = new UTF8Encoding() RijndaelManaged rj = new RijndaelManaged() Static public String DecryptRJ256(string cypher, string KeyString, string IVString) I think there’s nobody talked about this,I want to encrypt text for my project,from php(server) to maxscript,encrypt in php,then ,decrypt in maxscript,just text,or a long string,maybe need a little secure,after I searched google,I found there are a lot of examples using C# language,but I really don’t know how to translate them into maxscript,and I don’t know whether it is possible support in maxscript either.What I want is translate below codes to maxscript,I tired several days myself,but unlucky:īelow is C# side codes: public string Decode(string str)īyte decbuff = Convert.FromBase64String(str)
