Yes, we're still holding the lock while unwrapping. In retrospect this looks like a mistake, albeit one made for obvious reasons (it kept the control flow dead simple, which is generally a good idea when dealing with locks in an assembly language like C). So that's something we could try fixing, at which point maybe we'd get more benefit from multiple AES cores. _______________________________________________ Tech mailing list Tech@cryptech.is https://lists.cryptech.is/listinfo/tech
