@ -779,7 +779,7 @@ As we saw in the section <<public_key_derivation>>, a public key is a point (x,
elliptic curve. Because the curve expresses a mathematical function, a
point on the curve represents a solution to the equation and, therefore,
if we know the _x_ coordinate, we can calculate the _y_ coordinate by
solving the equation y^2^ mod p = (x^3^ + 7) mod p. That allows us to
solving the equation [.keep-together]#y^2^ mod p = (x^3^ + 7) mod p.# That allows us to
store only the _x_ coordinate of the public key point, omitting the _y_
coordinate and reducing the size of the key and the space required to
store it by 256 bits. An almost 50% reduction in size in every
