Block sizes for Rijndael and AES Managed.

[tassa]

Hello,

I've done some tweaking and have surfed the net, but haven't found a clear answer to my question:

Do both of these algorithm work only with a 128bit size block size?

Thanks in advance .

Yes. It seems like that is the case.

Edit: hold on. I found this:
AES has a fixed block size of 128 bits and a key size of 128, 192, or 256 bits, whereas Rijndael can be specified with block and key sizes in any multiple of 32 bits, with a minimum of 128 bits and a maximum of 256 bits.

I had found that also, however, I am under the impression that the block size can/is determined by the size of the IV, nevertheless, I haven't found any document that will prove me right.

I've done some tweaking around and have found that Rijndael supports key sizes of 64, 96, 128, 192, 256 bits and block sizes of 128, 192 and 256bits, whereas AES supports one block size - 128bits and key sizes of 128, 192 and 256 bits.

If you are to edit the block size of the Rijndael algorithm, you should then use the .BlockSize property to set the block size.
