Module artichoke_backend::extn::stdlib::securerandom

Secure random number generator interface.

This module implements the SecureRandom package from the Ruby Standard Library. It is an interface to secure random number generators which are suitable for generating session keys in HTTP cookies, etc.

You can use this library in your application by requiring it:

require 'securerandom'

This implementation of SecureRandom supports the system RNG via the getrandom crate. This implementation does not depend on OpenSSL.

Modules

hex	Functions for encoding sequences of bytes into base 16 hex encoding.
mruby	FFI glue between the Rust trampolines and the mruby C interpreter.
trampoline	Glue between mruby FFI and securerandom Rust implementation.

Structs

ArgumentError	Error that indicates an argument parsing or value logic error occurred.
DomainError	Error that indicates the given maximum value is not finite and cannot be used to bound a domain for generating random numbers.
RandomBytesError	Error that indicates the underlying source of randomness failed to generate the requested random bytes.
SecureRandom	A handle to the underlying secure random number generator.

Enums

Max	Max value when generating a random number from a range.
Rand	Random numeric value generated from the secure random number generator.
