how decrypt cryptojs using aes?

seem going round in circles in getting values match in console. values encryption of 'hello' match both applied server , client (sending 'hello' there no decryption value showing either.

the server side code in node post route:

var enc_key = "c2vjcmv0"; //'secret' app.post('/hello', function (req, res) {     console.log('post /hello');      var key = cryptojs.enc.base64.parse(enc_key);      console.log('key: ' + key);       console.log('client msg ("hello"): ' + req.body.msg_hello);      var encrypted = cryptojs.aes.encrypt("hello", key, {         mode: cryptojs.mode.ecb,         padding: cryptojs.pad.pkcs7     });      console.log('server msg "hello" encrypted to: ' + encrypted);      var decrypted = cryptojs.aes.decrypt(encrypted, key, {         mode: cryptojs.mode.ecb,         padding: cryptojs.pad.pkcs7     });      console.log('server msg decrypted: ' + hex2a(decrypted));      var decryptedclient = cryptojs.aes.decrypt(req.body.msg_hello, key, {         mode: cryptojs.mode.ecb,         padding: cryptojs.pad.pkcs7     });        console.log('client msg decrypted: ' + hex2a(decryptedclient));      res.end(json.stringify('{ response: "response" }')); });

any appreciated!

any ideas when firefox implement lengthadjust andtextlength?..... working svg application. lengthadjust , textlength working fine in chrome not working in fire fox . <svg viewbox = "0 0 500 300" version = "1.1"> <defs> <path id="s3" d="m 10,90 q 100,15 200,70" /> </defs> <g> <text font-size = "20"> <textpath xlink:href="#s3" textlength="205"> short text</textpath> </text> <use xlink:href="#s3" fill="none" stroke="black" stroke-width="1"/> </g> </svg> this implemented in firefox text elements (not textpath or tspan) in case that's ok though can move attribute text element. <svg viewbox = "0 0 500 300" version = "1.1"> <defs>

i using indy udp server read string of data. however, not know how work adata parameter. can around converting binary using bytetobin function below , convert hex using bintohex1 . feel stupid , works slow. know how can directly results without 2 conversions? thanks!! here codes: procedure tform1.idudpserver1udpread(athread: tidudplistenerthread; const adata: tidbytes; abinding: tidsockethandle); var buf: tidbytes; buffer: string; data_received: string; begin if bytestostring(adata) <> 'hello' begin buffer := hextostring('00'); setlength(buf, length(buffer)); copytidstring(buffer, buf, 0); abinding.sendto(abinding.peerip, abinding.peerport, buf); data_received := bintohex1(bytetobin(adata[1]) + bytetobin(adata[2]) + bytetobin(adata[3]) + bytetobin(adata[4]) + bytetobin(adata[5]) + bytetobin(adata[6]) + bytetobin(adata[7]) + bytetobin(adata[8]) + bytetobin(adata[9]) + bytetobin(adata[10]) + bytetobin(adata[11
