comment How many different keystreams can I produce with AES in Counter Mode?
@CodesInChaos, the key is fixed, the nonce incremented for each stream.. ex: this is my nonce = aaaaaaaaaaaaaaaa this is the counter = 0000000000000001 in the next stream the counter will increment, 0000000000000002

comment Are mouse movement coordinates useful as a seed for a RNG?
is there any proof the RNGCryptoServiceProvider Class is generating a secured random value?

do you think RNGCryptoServiceProvider Class is effective in generating a random value?

what do you mean "improve your accept rate"?

comment Counter Mode in Advanced Encryption Standard(AES) Algorithm
I have a question, after "00000000000000ff" what is the next counter value? is it "000000000000ff00" and then "000000000000ff01", "000000000000ff02"?

Thomas, where did you get this? do you have a link? or a pdf file about this?

comment Removing Padded Value in Decrypted Message
I do the RFC 5652 in padding, I just create a validation to validate if that byte is a padding or not. thanks @poncho

that's okay, It's more understandable now.

comment Removing Padded Value in Decrypted Message
I see.. but what if the message containing 0D 0D 0D 0D 0D 0D 0D 0D 0D 0D 0D 0D how can I determined if that is padded byte or a part of original message, that is a carriage return..

comment Removing Padded Value in Decrypted Message
I only understand in that is that if I only need 1 padding value all I need to do is to add this "01" if the padding that is need is 14, all I need to do is this.. "1414141414141414141414141414"

thanks @PaĆ­loEbermann, and now this question is more clear and specific.
