Method Details

engineGenerateCertificate

public abstract Certificate engineGenerateCertificate(InputStream inStream) throws CertificateException

Generates and initializes a Certificate from the provided input stream.

Parameters:

inStream - the stream from which the data is read to create the certificate.

Returns:

an initialized certificate.

Throws:

CertificateException - if parsing problems are detected.

engineGenerateCertificates

public abstract Collection<? extends Certificate> engineGenerateCertificates(InputStream inStream) throws CertificateException

Generates and initializes a collection of certificates from the provided input stream.

Parameters:

inStream - the stream from where data is read to create the certificates.

Returns:

a collection of certificates.

Throws:

CertificateException - if parsing problems are detected.

engineGenerateCRL

public abstract CRL engineGenerateCRL(InputStream inStream) throws CRLException

Generates and initializes a Certificate Revocation List (CRL) from the provided input stream.

Parameters:

inStream - the stream from where data is read to create the CRL.

Returns:

an CRL instance.

Throws:

CRLException - if parsing problems are detected.

engineGenerateCRLs

public abstract Collection<? extends CRL> engineGenerateCRLs(InputStream inStream) throws CRLException

Generates and initializes a collection of Certificate Revocation List (CRL) from the provided input stream.

Parameters:

inStream - the stream from which the data is read to create the CRLs.

Returns:

a collection of CRLs.

Throws:

CRLException - if parsing problems are detected.

engineGenerateCertPath

public CertPath engineGenerateCertPath(InputStream inStream) throws CertificateException

Generates a CertPath from the provided InputStream. The default encoding scheme is applied.

Parameters:

inStream - an input stream with encoded data.

Returns:

a CertPath initialized from the provided data.

Throws:

CertificateException - if parsing problems are detected.

engineGenerateCertPath

public CertPath engineGenerateCertPath(InputStream inStream, String encoding) throws CertificateException

Generates a CertPath (a certificate chain) from the given inputStream, assuming the given encoding from engineGetCertPathEncodings().

Throws:

CertificateException - if parsing problems are detected.

UnsupportedOperationException - if the provider does not implement this method.

engineGenerateCertPath

public CertPath engineGenerateCertPath(List<? extends Certificate> certificates) throws CertificateException

Generates a CertPath from the provided list of certificates. The encoding is the default encoding.

Parameters:

certificates - the list containing certificates in a format supported by the CertificateFactory.

Returns:

a CertPath initialized from the provided data.

Throws:

CertificateException - if parsing problems are detected.

UnsupportedOperationException - if the provider does not implement this method.

engineGetCertPathEncodings

public Iterator<String> engineGetCertPathEncodings()

Returns an Iterator over the supported CertPath encodings (as Strings). The first element is the default encoding.

Returns:

an iterator over supported CertPath encodings (as Strings).
