This is something I've been interested in too, so with some guidance from Vincent I put together a short example of doing this: https://gist.github.com/snoyberg/20243aae347b38ad09daaf8b129e2efb It's got some magic values in a few places (especially that 65!), and the usage of leftovers/B.append is far from efficient. However, it should get the general idea across. On Thu, Jul 6, 2017 at 7:58 AM, Ivan Lazar Miljenovic < ivan.miljenovic@gmail.com> wrote:
I have a use case for needing to use public key cryptography to encrypt a large amount of data in a streaming fashion (get it out of a DB, encrypt, put into an AWS S3 bucket).
The command-line gpg tool seems to be able to encrypt/decrypt data from stdin to stdout in a streaming fashion, but in my attempts to use it it seems very file-based for things like the keys to use (whereas I would prefer to be able to pass the public key as an actual value rather than a file; if nothing else because this is for tools that don't have email addresses to use and base their keys on for addressing).
Is there an existing library that can achieve this using conduit/pipes/whatever? cryptonite-conduit only covers hashing, hOpenPGP is poorly documented and I can't work out how to use it ("just follow the types" is difficult when Haddock docs don't link to the required types (seems to be because it uses the "import Module as X" trick for re-exporting everything but then everything from those modules isn't available).
Can anyone recommend a solution?
