  We construct a class of chiral fermionic CFTs from classical codes over
finite fields whose order is a prime number. We exploit the relationship
between classical codes and Euclidean lattices to provide the Neveu-Schwarz
sector of fermionic CFTs. On the other hand, we construct the Ramond sector
using the shadow theory of classical codes and Euclidean lattices. We give
various examples of chiral fermionic CFTs through our construction. We also
explore supersymmetric CFTs in terms of classical codes by requiring the
resulting fermionic CFTs to satisfy some necessary conditions for
supersymmetry.
