Key store options configuring a private key and its certificate based on Privacy-enhanced Electronic Email (PEM) files.

The key file must contain a non encrypted private key in PKCS8 format wrapped in a PEM block, for example:

 -----BEGIN PRIVATE KEY-----
 MIIEvgIBADANBgkqhkiG9w0BAQEFAASCBKgwggSkAgEAAoIBAQDV6zPk5WqLwS0a
 ...
 K5xBhtm1AhdnZjx5KfW3BecE
 -----END PRIVATE KEY-----
 

The certificate file must contain an X.509 certificate wrapped in a PEM block, for example:

 -----BEGIN CERTIFICATE-----
 MIIDezCCAmOgAwIBAgIEZOI/3TANBgkqhkiG9w0BAQsFADBuMRAwDgYDVQQGEwdV
 ...
 +tmLSvYS39O2nqIzzAUfztkYnUlZmB0l/mKkVqbGJA==
 -----END CERTIFICATE-----
 

The key and certificate can either be loaded by Vert.x from the filesystem:

 HttpServerOptions options = new HttpServerOptions();
 options.setPemKeyCertOptions(new PemKeyCertOptions().setKeyPath("/mykey.pem").setCertPath("/mycert.pem"));
 

Or directly provided as a buffer:

 Buffer key = vertx.fileSystem().readFileSync("/mykey.pem");
 Buffer cert = vertx.fileSystem().readFileSync("/mycert.pem");
 options.setPemKeyCertOptions(new PemKeyCertOptions().setKeyValue(key).setCertValue(cert));
