incompatibility

Hi,

I dont know if that is a bug, or if Im failling to find some special behaivor.
The fact is that i try port your program to perl and java. I did use the recomended implementation of rijndael for that languages, that implements ECB mode.
So i ported your CFB mode with salt.
The result was than perl and java versions are compatible, but none is compatible with your version.
I would apreciate if you tell me if you do more some special thing with basic rijndael-ecb mode, like the cfb and salt mode than i have found.

Thanks, and sorry about my english.

Here is my java port with cryptix 3.2.0 library providing rijndael:

key = new RawSecretKey\(&amp;quot;AES&amp;quot;, \(&amp;quot;ba1f2511fc30423bdbb183fe33f3dd0f&amp;quot;\).getBytes\(\)\);
aes = Cipher.getInstance\(&amp;quot;AES&amp;quot;\);
aes.initEncrypt\(key\);

private static void cfb(byte[] src) {
byte ch, idx = -1;
byte[] cfb_out = null;

for\(int i=0; i &amp;lt; src.length; ++i\) \{
    if \(idx &amp;lt; 0 || idx &amp;gt; 15\) \{
    cfb\_out = aes.update\(cfb\_blk\);
    idx = 0;
    \}
    ch=src\[i\];
    src\[i\]= \(byte\) \(ch ^ cfb\_out\[idx\]\);
    cfb\_blk\[idx++\]=ch; 
\}

}
