Does it matter for the security of AES how the byte array is encoded in C#? -

-

i have byte array encrypted using aes pass phrase encrypted using sha-256. works perfect, i'm wondering last part have encode byte array result of encryption. matter, robustness of end result how byte array encrypted, base64, conversion hexadecimal values, else?

logically speaking, doesn't matter since there aren't encoding methods , of time obvious one, base64, used. since i'm not versed cryptography want make sure.

take byte array example (random array of bytes example):

    [0] 182      [1] 238      [2] 54     [3] 24       [4] 69       [5] 224      [6] 105      [7] 13       [8] 5        [9] 52       [10]112      [11]71       [12]250      [13]163      [14]234      [15]234

this gives possible result in base64 (random result, not match above):

using bitconvertor transform hexadecimal values gives (random result, not match above):

a2ebca1945e8bc920532f068d27baef1

it's simple convert above results respective byte array , hard part start.

does matter, robustness of end result how byte array encrypted, base64, conversion hexadecimal values, else?

no, not @ all. long you're encoding in lossless format (which both base64 , hex are) that's fine. don't use encoding.ascii.getstring(...) - lossy , inappropriate. (don't use encoding @ task.)

just ask whether reverse encoding , original bytes - if so, you're fine. (and that's true hex , base64, assuming it's implemented.)

Hatching array of circles in AutoCAD using c# -

i beginner in autocad plugins .i have created array of circle using following code. now, have hatch circles in array .how that??how hatch circles @ once? moreover, how can return hatch method , use hatch objects.sorry language.thanks in advance. [assembly: commandclass(typeof(beamsection.class1))] namespace beamsection { public class class1 { //class1 obj = new class1(); [commandmethod("beamatsupport")] public void addlightweightpolyline() { // current document , database document acdoc = application.documentmanager.mdiactivedocument; database accurdb = acdoc.database; promptpointresult ppr = acdoc.editor.getpoint("\nselect starting point "); var ucs = acdoc.editor.currentusercoordinatesystem; point3d startingpt = ppr.value.transformby(ucs); list<double> radius = new list<double>(); radius.add(0.5);

so have been working on @ codecademy.com while trying learn python. don't know if blind , can't see why won't work or what. here's code won't let me use. function print variable if had typed in , print "empty" if didn't type anything. print "welcome english pig latin translator!" original = raw_input("what's name?") if len(original) > 0 print original else print "empty" if len(original) > 0 else the above lines contains syntax errors. try: if len(original) > 0: else: note added colons, ( : ).
