Package subtle implements functions that are often useful in cryptographic
code but require careful thought to use correctly.

Package-Level Functions* (total 8, in which 7 are exported)*
ConstantTimeByteEq returns 1 if x == y and 0 otherwise.
ConstantTimeCompare returns 1 if the two slices, x and y, have equal contents
and 0 otherwise. The time taken is a function of the length of the slices and
is independent of the contents. If the lengths of x and y do not match it
returns 0 immediately.
ConstantTimeCopy copies the contents of y into x (a slice of equal length)
if v == 1. If v == 0, x is left unchanged. Its behavior is undefined if v
takes any other value.
ConstantTimeEq returns 1 if x == y and 0 otherwise.
ConstantTimeLessOrEq returns 1 if x <= y and 0 otherwise.
Its behavior is undefined if x or y are negative or > 2**31 - 1.
ConstantTimeSelect returns x if v == 1 and y if v == 0.
Its behavior is undefined if v takes any other value.
XORBytes sets dst[i] = x[i] ^ y[i] for all i < n = min(len(x), len(y)),
returning n, the number of bytes written to dst.
If dst does not have length at least n,
XORBytes panics without writing anything to dst.
