You can use Media Services to deliver HTTP Live Streaming (HLS) and Smooth Streaming encrypted with the AES by using 128-bit encryption keys.

I want to generate AES encryption key to be sent to the the other party in order to communicate securely.

Tag: c#,byte,bit,xor,bitarray. I'm trying to learn simple cryptology and as a starter I'm trying to achieve the following.

A function, taking two 128 bit params (key and plaintext) as input and returning their XOR. I know XOR is not safe but I'm starting out with a simple example.

This is what I have tried:

Encrypter.cs :

My problem:

I'm struggling with what to put as the key and plaintext. How can I ensure that the values are exactly 128 bit each?

E.g. B25829846AED8 is apparently a 128 bit WEP key. If I assign this to my key variable and when I enter the encrypt method the keyBits.Length property has the value 208. This is what I don't get. Also the parameter key has the length 26, which I'm also confused by.

Why is the key-length 26?

C#-strings is in unicode, so you can write all characters out there eg. Chinese, Japanese, etc. etc. That takes two bytes. 13*2=26.

Is your wep-key 128 bits You've got a key for 128 bit wep-protocoll which is using 104 bit keys. (fun times) Wiki on Wep

But as far as I understand you're not trying to implement wep, you're trying to encode something. Take two random integers translate them to bytes and put them after each other. BAM- 128 bits :)

Other than that you seam to have it under control, good luck :)

Unconstrained type parameters casting

c#,.net,types,casting

The compiler sees the T2 and T identifiers and helpfully informs you that those types seem unrelated. That's absolutely correct, as they have no relation: there are no generic constraints that would assert any relations between them (I'm not saying that would be useful here though :) ). Whether this..
