import elligator

# Generate keys
while True:
    private = urandom(32)
    (valid, public, representative) = elligator.scalarbasemult(private)
    if valid:
        break


# Convert a uniform representative value for Curve25519 public key, 
# as produced by scalarbasemult, to a Curve25519 public key
public = elligator.representativetopublic(representative)
