securemem

Securemem provides memory chunks that allow auto-scrubbing of the memory after use, and constant time equality.

Documentation: securemem on hackage

Interacting with securemem

It’s recommended to use the Byteable instance when providing an interface that takes a securemem. It allow legacy code, and work in progress code to interface with securemem more easily.

older base

On older base, the memory is not scrubbed: upgrade your GHC to 7.6.0 or above.

TODO

add a custom memory allocator that give mlocked memory chunks.
