cert-genThis is a Rust function that generates a new SSL certificate and private key signed by a specified Certificate Authority (CA). The function takes two arguments:
ca_cert: A Certificate object representing the CA to sign the new certificate with.dn_name: A String representing the domain name to generate the certificate for.The function creates a new DistinguishedName object with the specified domain name, and a new CertificateParams object with the following properties:
distinguished_name: The DistinguishedName object with the specified domain name.not_before: The current date and time.not_after: The current date and time plus 20 years.subject_alt_names: A Vec<SanType> containing the domain name, "localhost", and the IP addresses 127.0.0.1 and ::1.The function then creates a new Certificate object using the CertificateParams object, and signs it with the specified CA using the serialize_pem_with_signer method. Finally, the function saves the signed certificate and private key files to disk in the certs directory within the directory you run the command from, with filenames based on the specified domain name.
To use this function in your Rust code, you'll need to import the necessary crates and dependencies, and then call the function with the required arguments. Here's an example:
```rust use rcgen::Certificate; use signedcertwith_ca;
// Assume ca_cert is a Certificate object representing the CA to sign the new certificate with.
let dnname = "example.com".tostring();
signedcertwithca(cacert, dn_name); ```
This will generate a new SSL certificate and private key for the domain example.com, signed by the specified CA.
This function depends on the following Rust crates:
rcgen: Used to generate SSL certificates and private keys. std::fs: Used to save the generated files to disk.
