Libsodium utility functions
| add_le | add_le() treats x and y as unsigned little-endian numbers and adds y to x
modulo 2^(8*len) in constant time.
|
| increment_le | increment_le() treats x as an unsigned little-endian number and increments it in
constant time.
|
| memcmp | memcmp() returns true if x[0], x[1], ..., x[len-1] are the
same as y[0], y[1], ..., y[len-1]. Otherwise it returns false.
|
| memzero | memzero() tries to effectively zero out the data in x even if
optimizations are being applied to the code.
|
| mlock | mlock() locks memory given region which can help avoiding swapping the
sensitive memory region to disk.
|
| munlock | munlock() unlocks memory region.
