Class FileCertReader

java.lang.Object
  org.kth.pdc.grid.utility.FileCertReader

public class FileCertReader
extends Object

Reads all certificates from given files, accepts binary form of DER encoded certs and the Base64 form of the DER encoded certs (PEM). The base64 certs can contain garbage in front of the actual certificate that has to begin with "-----BEGIN". Should accept multiple certs in one file, not tested!

Constructor Summary

FileCertReader()
Creates a new instance of CertReader

FileCertReader(Provider provider)
Creates a new instance of CertReader with the specified provider

Method Summary

Object	objectReader(BufferedInputStream binStream, int type) Reads a certificate or a CRL from the stream, doing some error correction.
Vector	readAnchors(String files) Reads the certificates from the files defined in the argument and makes TrustAnchors from them.
Vector	readCerts(String files) Reads the certificates from the files defined in the argument.
Vector	readCRLs(String files) Reads the certificate revocation lists (CRLs) from the files defined in the argument.
Vector	readFile(File certFile, int type) Reads the objects of given type from the File
Object	readObject(BufferedInputStream binStream, int type) Does the actual reading of the object.
KeyStore	readProxy(BufferedInputStream stream, String storePasswd)
static void	skipEmptyLines(BufferedInputStream stream) Skips empty lines in the stream.
static void	skipToCertBeginning(BufferedInputStream stream) Skips everything in front of "-----BEGIN" in the stream.
