Usage

From source file:pv181.jca.Globals.java

/**
 * Basic PEM file parser, returns parsed object.
 * @param s/*  ww  w .ja  v a 2s  .c om*/
 * @return
 * @throws IOException 
 */
public static Object readPEM(InputStream s) throws IOException {
    // initialize buffered reader of input stream
    Reader fRd = new BufferedReader(new InputStreamReader(s));

    // PEM parser from Bouncy castle library
    PEMParser parser = new PEMParser(fRd);

    // Parse given PEM file, decide if it is X509Certificate
    return parser.readObject();
}
