                                                  GeneralSecurityException

Deprecated.

Generates a new certificate using the Bouncy Castle implementation.

Parameters:

domainName - the X500 domain name for the certificate

publicKey - the public key of the cert

privateKey - the private key of the cert

issuerKeys - the certificate and private key of the issuer

from - validity start time

to - validity end time

serial - a BigInteger object.

applicationUri - the OPC UA ApplicationUri of the application - added to SubjectAlternativeName

hostNames - the additional host names to ass to SubjectAlternativeName

Returns:

the generated certificate

Throws:

GeneralSecurityException - if the generation fails

IOException - if the generation fails due to an IO exception

generateIssuerCert

public static X509Certificate generateIssuerCert(PublicKey publicKey,
                                                 PrivateKey privateKey,
                                                 KeyPair issuerKeys,
                                                 String commonName,

                                                 IOException

Deprecated.

Build a X509 V3 certificate to use as an issuer (CA) certificate. The certificate does not define OPC UA specific fields, so it cannot be used for an application instance certificate.

Parameters:

publicKey - the public key to use for the certificate

privateKey - the private key corresponding to the publicKey

issuerKeys - the certificate and private key of the certificate issuer: if null a self-signed certificate is created.

commonName - the CommonName to use for the subject of the certificate.

serialNr - a BigInteger object.

startDate - a Date object.

expiryDate - a Date object.

Returns:

a X509Certificate object.

Throws:

GeneralSecurityException - if any.

IOException - if any.

getSubjectAlternativeNames

public static Collection<List<?>> getSubjectAlternativeNames(X509Certificate cert)
                                                      throws CertificateParsingException

Deprecated.

getSubjectAlternativeNames.

Parameters:

cert - a X509Certificate object.

Returns:

a Collection object.

Throws:

CertificateParsingException - if any.

PKCS5PasswordToBytes

public static byte[] PKCS5PasswordToBytes(char[] password)

Deprecated.

Converts a password to a byte array according to the scheme in PKCS5 (ascii, no padding).

Parameters:

password - a character array representing the password.

Returns:

a byte array representing the password.

writeToPem

public static void writeToPem(Object key,
                              File savePath,
                              String password,
                              String algorithm)
                       throws IOException

Deprecated.

Write a certificate or private key to a PEM file with a password.

Parameters:

key - certificate of private key

savePath - a File object.

password - a String object.

algorithm - a String object.

Throws:

FileNotFoundException - if any.

IOException - if any.
