|
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.

Generates a self-signed [X509Certificate] from the given [CryptoKey] and [code]issuer_name[/code]. The certificate validity will be defined by [code]not_before[/code] and [code]not_after[/code] (first valid date and last valid date). The [code]issuer_name[/code] 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.
|
|
[codeblock]
|
|
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")
