Hello, I'm currently working on an implementation of GOST for the GNU Classpath project, and I'm running up into the problem of actually testing my implementation, available here: http://www.surgo.net/classpath/GOST.java
As you can see in the file, I'm using the S-Boxes detailed on Applied Cryptography, 2nd ed., page 333. As there are no published test vectors, I need to make some sort of interoptability test with another implementation. To that end, I was wondering which S-Boxes you use? It looks like you use the same S-Boxes that I do, but you then have some sort of speed-up table that I don't entirely understand. In addition, what is the format for the test vectors you have in your gostval.dat file? Key/plaintext/ciphertext? If it's that, I seem to have some subtle bug in my implementation that makes encryption wrong, though decryption ends up correct. Thanks for the information, -- Morgon Kanter <[EMAIL PROTECTED]>
