Generates a certificate revocation list (CRL) object and initializes it with the data read from the input stream {@code inStream}.
In order to take advantage of the specialized CRL format supported by this certificate factory, the returned CRL object can be typecast to the corresponding CRL class. For example, if this certificate factory implements X.509 CRLs, the returned CRL object can be typecast to the {@code X509CRL} class.
Note that if the given input stream does not support {@link java.io.InputStream#mark(int) mark} and{@link java.io.InputStream#reset() reset}, this method will consume the entire input stream. Otherwise, each call to this method consumes one CRL and the read position of the input stream is positioned to the next available byte after the inherent end-of-CRL marker. If the data in the input stream does not contain an inherent end-of-CRL marker (other than EOF) and there is trailing data after the CRL is parsed, a {@code CRLException} is thrown.
@param inStream an input stream with the CRL data.
@return a CRL object initialized with the datafrom the input stream.
@exception CRLException on parsing errors.
