Method Detail

md5Hex

public static String md5Hex(File file)

Calculates the MD5 digest and returns the value as a 32 character hex string.

Parameters:

file - file to digest.

Returns:

MD5 digest as a hex string.

md5Hex

public static String md5Hex(InputStream in)
                     throws IOException

Throws:

IOException

md5Hex

public static String md5Hex(InputStream inStream,
                            OutputStream outStream)
                     throws IOException

calculates MD5 checksum based on inStream and writes bytes read to outStream. Both streams will be closed.

Parameters:

inStream -

outStream -

Returns:

MD5 checksum

Throws:

IOException

md5Hex

public static String md5Hex(InputStream originalInStream,
                            MD5CheckSum.InputStreamCallback inputStreamCallback)
                     throws IOException

Convenience method that calculates MD5 checksum based on inputStream while still allowing other code to consume same data from input stream given by inputStreamCallback.

MD5CheckSum.MD5ReaderThread consumes originalInStream to calculate MD5 checksum based on it, but it writes all original bytes to pipedOutStream that is made available as InputStream to the inputStreamCallback which can handle given input stream as if it would read originalInStream

Parameters:

originalInStream -

inputStreamCallback - - used to perform custom action with the data available from originalInStream

Returns:

MD5 checksum

Throws:

IOException
