Detailed Description

An X25519 unsigned 258-bit integer.

This is an unsigned integer N in the finite field of integers modulo the prime p=2^255-19.

In this representation, N is encoded as any big integer that is in the same congruence class as N (i.e that has the same value as N modulo p) and that lies within the 258-bit range [0,8p-1].

This type can be used as an input for multiplication (but not for addition or subtraction).

Addition or subtraction will produce an output of this type.
