Agilebits 1Password support and Design Flaw?

I guess you are using the table-based approach (such as what OpenSSL does and not what the AES sample from AMD APP SDK does). Do you store the expanded key in local memory or you are doing that on-the-fly? Asking about that because AES decryption is funny if you are doing the key scheduling on-the-fly, for some time I thought that would be impossible, but it is possible and quite feasible, you can even "pre-cache" some data to save some ALU operations on each round.

hey gat3way, i'm doing an all-precomputed approach so that there is not a single rotate left. this is defenitly different from the amd app sdk example but i dont know anything about the openssl one since i never looked at it.
