80-bit security key instead of 128 #35

Dear all,

Thank you very much for your hard work and this wonderfull project.

I would like to know if it is possible to use a 80 bit security key instead of 128 as written in the documentation

Kind regards

That estimate has been reconsidered in 2020, apparently it actually does provide only 80 bit. For 128 bit some parameters need to be bumped (see the reference implementation in Julia, https://github.com/nucypher/TFHE.jl/blob/master/src/api.jl#L55).
