Major Description
When passing more than one algorithm to CommonsDigester constructor and
then trying to digest a file which is larger than 7.5 MB, results wrong
hashe calculation for all the algorithms except the first.
The next code will reproduce the bug:
// The file that was used w as a simple plain text file with size > 7.5 MB
File file = new File("testLargeFile.txt");
BufferedInputStream bufferedInputStream = new BufferedInputStream(new FileInputStream(file));
Metadata metadata = new Metadata();
CommonsDigester digester = new CommonsDigester(20000000,
CommonsDigester.DigestAlgorithm.MD5,
CommonsDigester.DigestAlgorithm.SHA1,
CommonsDigester.DigestAlgorithm.SHA256);
digester.digest(bufferedInputStream, metadata, null);
// Will print correct MD5 but wrong SHA1 and wrong SHA256
System.out.println(metadata);
Initial direction: it seems that the inner buffered stream that is being used doesn't reset to 0 position after the first algorithm.
