[Haskell-beginners] TLS, PGP and maybe more crypto-stuff

Hi I am considering using Haskell in my next project. However the very core of my application depends on strong cryptographic algorithms securing communication. I thought about using GnuPG (PGP) but did not find Haskell library (I admit, I did not search for long). So my idea was to look into TLS based stuff, but here I found few different libraries. For a moment I thought of developing something basing on ECC, but again I did not find anything. My questions are: * is there a (decent) GnuPG (PGP) library in Haskell? * what TLS (possibly 1.2) library would you suggest? * is there a ECC library? -- Mateusz
