Load Base64-encoded X.509 Certificate (.cer)

See more Certificates Examples

Loads a digital certificate from a base64 encoded DER X.509 Certificate (.cer, .crt) and fetches information about the cert. Rust

let cert = chilkat::Cert::new();

// LoadFromFile will load virtually any certificate format file.
// It will auto-recognize the format and load appropiately.
// A base64-encoded DER X.509 certificate file
// contains the binary DER in base64 encoded form.
// Therefore, it is a text file that will begin like this:
// -----BEGIN CERTIFICATE-----
// MIIFbjCCBFagAwIBAgIGdDPNv/L0MA0GCSqGSIb3DQEBBQUAMIHKMQswCQYDVQQG
// EwJVUzEQMA4GA1UECBMHQXJpem9uYTETMBEGA1UEBxMKU2NvdHRzZGFsZTEaMBgG
// ...

if cert.load_from_file("/Users/chilkat/testData/cer/chilkat_base64.cer").is_err() {
    println!("{}", cert.last_error_text());
    return;
}

// DN = "Distinguished Name"
println!("SubjectDN:{}", cert.subject_dn());

println!("Common Name:{}", cert.subject_cn());
println!("Issuer Common Name:{}", cert.issuer_cn());

println!("Serial Number:{}", cert.serial_number());
