## RNG removal
## High-level API tweaks for PSA
A number of existing functions now take a different list of arguments, to migrate them to the PSA API.
### Public functions no longer take a RNG callback
Functions that need randomness no longer take an RNG callback in the form of `f_rng, p_rng` arguments. Instead, they use the PSA Crypto random generator (accessible as `psa_generate_random()`). All software using the X.509 or SSL modules must call `psa_crypto_init()` before calling any of the functions listed here.
