Constructor Detail

### CertificateUtils

    public CertificateUtils()

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.

### createCSR

  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`
