Crypto.Init
Description
Libsodium initialisation.
Synopsis
- sodiumInit :: IO ()
- data SodiumInitException = SodiumInitFailed
Documentation
sodiumInit :: IO () Source #
Initialise libsodium.
This is just sodium_init() from libsodium. Calling it before using
any Sodium functions is optional, but strongly recommended.
This function does the following:
- Open
/dev/urandom(on Unix) to make it accessible even afterchroot(). - Make all libsodium functions thread-safe.
- Benchmark different implementations of cryptographic primitives provided and choose the best ones.
This function itself is thread-safe (since libsodium-1.0.11).
