  - ### Method Detail

    - #### generateKeyPair

          public static KeyPair generateKeyPair()

      Generates a RSA 2048 keypair.

    - #### createCSR

          public static byte[] createCSR(DistinguishedName distingueshedName,
                                         KeyPair keyPair)

      Generates a PKCS10 certificate request based on the given `DistinguishedName` and the keypair.

      The `DistinguishedName` is used for subject generation.

    - #### generateCert

          public static X509Certificate generateCert(PublicKey rqPubKey,
                                                     BigInteger serialNr,
                                                     Credential cred)
                                              throws TechnicalConnectorException

      Generates a self signed certificate based on the given `Credential`
      Throws:
        `TechnicalConnectorException`

    - #### generateCert

          public static X509Certificate generateCert(KeyPair pair)

      Generates a self signed certificte with a C=Dummy as subject.

    - #### obtainSerialNumber

          public static BigInteger obtainSerialNumber(PrivateKey key,
                                                      byte[] challenge)
                                               throws TechnicalConnectorException

      Extract the serialnumber from the challenge.
      Throws:
        `TechnicalConnectorException`

    - #### toX509Certificate

          public static X509Certificate toX509Certificate(byte[] cert)

      Convert a byte array to a `X509Certificate`
