Does this library implement a padding algorithm?

[Jethril]

Hello,

Please pardon my naive question. I would like to know whether this library provides a padding algorithm.
I read this function: ntru.c:204 and this issue but I'm not sure whether I understood correctly.

If it does not implement a padding algorithm, does the encrypted output remains safe?
(I only encrypt a symmetric key as explained in the issue)

Thanks.
