Struct Crypto
Access to advanced cryptographic functionalities.
struct Crypto
;
The Crypto class allows you to access some more advanced cryptographic functionalities in Godot. For now, this includes generating cryptographically secure random bytes, and RSA keys and self-signed X509 certificates generation. More functionalities are planned for future releases.
extends Node
var crypto = Crypto.new() var key = CryptoKey.new() var cert = X509Certificate.new()
func ready(): # Generate new RSA key. key = crypto.generate_rsa(4096) # Generate new self-signed certificate with the given key. cert = crypto.generate_self_signed_certificate(key, "CN=mydomain.com,O=My Game Company,C=IT") # Save key and certificate in the user folder. key.save("user://generated.key") cert.save("user://generated.crt")

Methods
| Name | Description |
|---|---|
generateRandomBytes
|
Generates a PoolByteArray of cryptographically secure random bytes with given size.
|
generateRsa
|
Generates an RSA CryptoKey that can be used for creating self-signed certificates and passed to StreamPeerSSL.
|
generateSelfSignedCertificate
|
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.
