Method Details

generateAlias

static <T extends Certificate> String generateAlias(T certificate)

loadCertificate

static List<Certificate> loadCertificate(Path path)

Loads certificates from the filesystem and maps it into a list of Certificate.
Supported input format: PEM, P7B and DER

loadCertificate

private static <T> List<Certificate> loadCertificate(Function<T,InputStream> resourceMapper,
 T[] resources)

parseCertificate

private static List<Certificate> parseCertificate(InputStream certificateStream)

Tries to map the InputStream to a list of Certificate. It assumes that the content of the InputStream is either PEM, P7B or DER. The InputStream will copied into an OutputStream so it can be read multiple times.

isPemFormatted

private static boolean isPemFormatted(String certificateContent)

isP7bFormatted

private static boolean isP7bFormatted(String certificateContent)

parsePemCertificate

static List<Certificate> parsePemCertificate(String certificateContent)

Parses PEM formatted certificates containing a header as -----BEGIN CERTIFICATE----- and footer as -----END CERTIFICATE----- or header as -----BEGIN PKCS7----- and footer as -----END PKCS7----- with a base64 encoded data between the header and footer.

parseP7bCertificate

static List<Certificate> parseP7bCertificate(String certificateContent)

Parses P7B formatted certificates containing a header as -----BEGIN PKCS7----- and footer as -----END PKCS7----- with a base64 encoded data between the header and footer.

parseCertificate

private static List<Certificate> parseCertificate(Matcher certificateMatcher)

parseDerCertificate

static List<Certificate> parseDerCertificate(InputStream certificateStream)
