-* 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
-* size_t len: Amount of bytes to be copied
-* uint8_t b: Condition bit; has to be in {0,1}
