libsodium as the underlying driver.
## INSTALL/Requirements:
## INSTALL/Requirements
* Erlang/OTP above 17.3. This library *needs* the dirty scheduler
implementation from 17.3 and onwards. The library relies on dirty
scheduler support in order to handle long-running cryptography jobs,
by moving them off the main Erlang scheduler and letting the dirty
schedulers handle the work. This keeps the Erlang VM responsive while
doing large amounts of cryptographic processing.
* Is tested with Erlang 22.3. Erlang version 21 *may* work, but that isn't
the current testing target.
* New-ish Erlang installation. Tested back to version 22.3, but version 21 *may*
work as well.
* *Requires* the libsodium library, and has been tested with version
1.0.18. Lower versions might work, or they might fail to compile,
due to missing functionality.
*Note:* If installing on systems which cuts packages into
subpackages, make sure you also get the "-dev" package containing
the header files necessary in order to compile software linking to
libsodium.
