Java Utililty Methods MD5 Stream

String computeMD5(InputStream inputStream)
Compute MD5 for a stream

final MessageDigest md5 = MessageDigest.getInstance("MD5");
byte[] temp = new byte[4096];
int read = inputStream.read(temp);
while (read >= 0) {
 md5.update(temp, 0, read);
 read = inputStream.read(temp);
inputStream.close();
...

String computeMd5(InputStream is)
compute a hexadecimal, 32-char md5 string for content from a stream.

if (is == null)
 return null;
MessageDigest digest = MessageDigest.getInstance("MD5");
try {
 byte[] buffer = new byte[8192];
 int read;
 while ((read = is.read(buffer)) > 0) {
 digest.update(buffer, 0, read);
...

String computeMD5(InputStream message)
Computes the MD5 message digest of an InputStream and returns it as a hexidecimal String.

int ch;
ByteArrayOutputStream out = new ByteArrayOutputStream();
while ((ch = message.read()) != -1) {
 out.write(ch);
out.close();
return computeMD5(out.toByteArray());

String computeMD5checksum(InputStream input)
Computes the MD5 checksum of the bytes in the InputStream.

DigestInputStream dis = null;
Formatter formatter = null;
try {
 MessageDigest md = MessageDigest.getInstance(DIGEST_MD5);
 dis = new DigestInputStream(input, md);
 while (-1 != dis.read())
 ;
 byte[] digest = md.digest();
...

byte[] computeMd5Hash(InputStream is)
Computes the MD5 hash of the data in the given input stream and returns it as an array of bytes.

return computeHash(is, MessageDigest.getInstance("MD5"));

byte[] computeMD5Hash(InputStream is)
compute MD Hash

MessageDigest messageDigest = MessageDigest.getInstance("MD5");
byte[] buffer = new byte[1024 * 1024];
int bytesRead;
while ((bytesRead = is.read(buffer, 0, buffer.length)) != -1) {
 messageDigest.update(buffer, 0, bytesRead);
return messageDigest.digest();

byte[] computeMD5Hash(InputStream is)
Computes the MD5 hash of the data in the given input stream and returns it as an array of bytes.

BufferedInputStream bis = new BufferedInputStream(is);
try {
 MessageDigest messageDigest = MessageDigest.getInstance("MD5");
 byte[] buffer = new byte[16384];
 int bytesRead = -1;
 while ((bytesRead = bis.read(buffer, 0, buffer.length)) != -1) {
 messageDigest.update(buffer, 0, bytesRead);
 return messageDigest.digest();
} finally {
 try {
 bis.close();
 } catch (Exception e) {
 System.err.println("Unable to close input stream of hash candidate: " + e);
