Constructor Details

BERReader

public BERReader(byte[] in)
Create a new DER reader from a byte array.
Parameters:
in - The encoded bytes.

public BERReader(byte[] in,
                 int off,
                 int len)

BERReader

public BERReader(InputStream in)
Create a new DER readed from an input stream.
Parameters:
in - The encoded bytes.

Method Details

peek

public int peek()
            throws IOException

read

public DERValue read()
            throws IOException
Decode a single value from the input stream, returning it in a new DERValue. By "single value" we mean any single type in its entirety -- including constructed types such as SEQUENCE and all the values they contain. Usually it is sufficient to call this method once to parse and return the top-level structure, then to inspect the returned value for the proper contents.
Overrides:
read in interface DERReader
Returns:
The parsed DER structure.
Throws:
IOException - If an error occurs reading from the input stream.
