-* Name:        verify
-*
-* Description: Compare two arrays for equality in constant time.
-*
-* Arguments:   const uint8_t *a: pointer to first byte array
-*              const uint8_t *b: pointer to second byte array
-*              size_t len:       length of the byte arrays
-*
-* Returns 0 if the byte arrays are equal, 1 otherwise

-* Name:        cmov
-*
-* Description: Copy len bytes from x to r if b is 1;
-*              don't modify x if b is 0. Requires b to be in {0,1};
-*              assumes two's complement representation of negative integers.
-*              Runs in constant time.

-*              const uint8_t *x: pointer to input byte array

-*              uint8_t b:        Condition bit; has to be in {0,1}
