I am trying to create an ABE by using charm-crypto library, I managed to generate the master secret key (msk) and the master public key (mpk) :
group = PairingGroup('SS512')
cpabe = CPabe09(group)
(msk, mpk) = cpabe.setup()
now I need to export those keys to a file, and to import them later if I need.
It's possible to convert msk (for example) to string by using :
st =str(msk)
But my question is how to get the msk from a string ?
I tried to store the keys by using "pickle", but it doesn't work :(
Thank you for your answers!
