Struct gdnative_bindings_lily::Crypto

pub struct Crypto { /* fields omitted */ }

core class Crypto inherits Reference (reference counted).

Official documentation

See the documentation of this class in the Godot engine’s official documentation. The method descriptions are generated from it and typically contain code samples in GDScript, not Rust.

Memory management

The lifetime of this object is automatically managed through reference counting.

Class hierarchy

Crypto inherits methods from:

• Reference
• Object

Safety

All types in the Godot API have “interior mutability” in Rust parlance. To enforce that the official thread-safety guidelines are followed, the typestate pattern is used in the Ref and TRef smart pointers, and the Instance API. The typestate Access in these types tracks whether the access is unique, shared, or exclusive to the current thread. For more information, see the type-level documentation on Ref.

Implementations

impl Crypto

pub fn new() -> Ref<Self, Unique>

Creates a new instance of this object.

This is a reference-counted type. The returned object is automatically managed by Ref.

pub fn generate_random_bytes(&self, size: i64) -> ByteArray

Generates a [PoolByteArray] of cryptographically secure random bytes with given size.

pub fn generate_rsa(&self, size: i64) -> Option<Ref<CryptoKey, Shared>>

Generates an RSA CryptoKey that can be used for creating self-signed certificates and passed to [method StreamPeerSSL.accept_stream].

pub fn generate_self_signed_certificate(
    &self,
    key: impl AsArg<CryptoKey>,
    issuer_name: impl Into<GodotString>,
    not_before: impl Into<GodotString>,
    not_after: impl Into<GodotString>
) -> Option<Ref<X509Certificate, Shared>>

Sample code is GDScript unless otherwise noted.

Generates a self-signed X509Certificate from the given CryptoKey and issuer_name. The certificate validity will be defined by not_before and not_after (first valid date and last valid date). The issuer_name must contain at least “CN=” (common name, i.e. the domain name), “O=” (organization, i.e. your company name), “C=” (country, i.e. 2 lettered ISO-3166 code of the country the organization is based in). A small example to generate an RSA key and a X509 self-signed certificate.

var crypto = Crypto.new()
# Generate 4096 bits RSA key.
var key = crypto.generate_rsa(4096)
# Generate self-signed certificate using the given key.
var cert = crypto.generate_self_signed_certificate(key, "CN=example.com,O=A Game Company,C=IT")

Default Arguments

• issuer_name - "CN=myserver,O=myorganisation,C=IT"
• not_before - "20140101000000"
• not_after - "20340101000000"

Methods from Deref<Target = Reference>

pub fn init_ref(&self) -> bool

Initializes the internal reference counter. Use this only if you really know what you are doing. Returns whether the initialization was successful.

Trait Implementations

impl Debug for Crypto

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Deref for Crypto

type Target = Reference

The resulting type after dereferencing.

fn deref(&self) -> &Reference

Dereferences the value.

impl DerefMut for Crypto

fn deref_mut(&mut self) -> &mut Reference

Mutably dereferences the value.

impl GodotObject for Crypto

type RefKind = RefCounted

The memory management kind of this type. This modifies the behavior of the Ref smart pointer. See its type-level documentation for more information.

fn class_name() -> &'static str

fn null() -> Null<Self>

Creates an explicitly null reference of Self as a method argument. This makes type inference easier for the compiler compared to Option.

fn new() -> Ref<Self, Unique> where
    Self: Instanciable, 

Creates a new instance of Self using a zero-argument constructor, as a Unique reference.

fn cast<T>(&self) -> Option<&T> where
    T: GodotObject + SubClass<Self>, 

Performs a dynamic reference downcast to target type.

fn upcast<T>(&self) -> &T where
    Self: SubClass<T>,
    T: GodotObject, 

Performs a static reference upcast to a supertype that is guaranteed to be valid.

unsafe fn assume_shared(&self) -> Ref<Self, Shared>

Creates a persistent reference to the same Godot object with shared thread access.

unsafe fn assume_thread_local(&self) -> Ref<Self, ThreadLocal> where
    Self: GodotObject<RefKind = RefCounted>, 

Creates a persistent reference to the same Godot object with thread-local thread access.

unsafe fn assume_unique(&self) -> Ref<Self, Unique>

Creates a persistent reference to the same Godot object with unique access.

unsafe fn try_from_instance_id<'a>(id: i64) -> Option<TRef<'a, Self, Shared>>

Recovers a instance ID previously returned by Object::get_instance_id if the object is still alive. See also TRef::try_from_instance_id.

unsafe fn from_instance_id<'a>(id: i64) -> TRef<'a, Self, Shared>

Recovers a instance ID previously returned by Object::get_instance_id if the object is still alive, and panics otherwise. This does NOT guarantee that the resulting reference is safe to use.
