My view is that Haskell's performance is very seldom the limiting factor

of course. when someone said about GPG i just mentioned that this project may be hihgly speed-dependent and this case Haskell is definitely not the solution

I highly disagree. Why would you want to write 99% of your code in a tedious and error-prone way to get speed in 1% of your code? Isn't it better to write that 1% of the code in a slightly more tedious way (Haskell imitating C), or even call a foreign function for it?

I completely agree ... <...>

I happen to think Haskell would be very well suited for this since the current project seems to be plagued by problems typical for C, and higly atypical for Haskell (book-keeping bugs, sometimes also leading to security issues).

... but I wonder: GPG, AFAIK undertakes some special measures to ensure that neither clear text nor private keys are paged out to the disk (since it might be recovered from there by "the enemy"). How would you lock data in memory in Haskell? Would that be possible? It seems to me that all participants in this thread have missed this point so far. Regards -- Markus
