| randombytes | randombytes() randomly generates size bytes of data.
|
| randombytes_buf_deterministic | WARNING: you should only use this function for testing purposes or a known good use case
in which it is acceptable to rely on the secrecy of the seed passed to
randombytes_buf_deterministic. The function is (as its name suggests) entirely deterministic
given knowledge of the seed. It does not incorporate entropy of any form and should almost
never be used for cryptographic purposes. If you need to generate a deterministic stream of
cryptographic quality pseudo random data you’re better suited using a stream cipher directly
e.g. one of the stream ciphers exposed in sodiumoxide::crypto::stream or
the higher level secretstream API.

| randombytes_buf_deterministic_into | WARNING: using this function in a cryptographic setting is dangerous. Read the full
documentation of randombytes_buf_deterministic() before proceeding.
|
| randombytes_into | randombytes_into() fills a buffer buf with random data.
|
| randombytes_uniform | randombytes_uniform() returns an unpredictable value between 0 and
upper_bound (excluded). It guarantees a uniform distribution of the
possible output values even when upper_bound is not a power of 2. Note
that an upper_bound < 2 leaves only a single element to be chosen, namely
0.
