Hello, rand.Read() is based on io.ReadFull, which already returns an error when n != len(p):
rand.Read()
io.ReadFull
n != len(p)

Furthermore, this is also written into the documentation:
Read is a helper function that calls Reader.Read using io.ReadFull. On return, n == len(b) if and only if err == nil.
Therefore, checking n != len(p) after rand.Read() is useless.
