+/**
+ * brainpoolP160t1
+ *
+ * This curve is a twisted version of brainpoolP160r1 with A = -3. With brainpool,
+ * the curves ending in r1 are the "regular" curves and the curves ending in "t1"
+ * are the twisted version of the r1 curves. Per https://tools.ietf.org/html/rfc5639#page-7
+ * you can convert a point on an r1 curve to a point on a t1 curve thusly:
+ *
+ *     F(x,y) := (x*Z^2, y*Z^3)
+ *
+ * The advantage of A = -3 is that some of the point doubling and point addition can be
+ * slightly optimized. See http://hyperelliptic.org/EFD/g1p/auto-shortw-projective-3.html
+ * vs http://hyperelliptic.org/EFD/g1p/auto-shortw-projective.html for example.
+ *
+ * phpseclib does not currently take advantage of this optimization opportunity
+ *
+ * PHP version 5 and 7
