Description

The list of methods to do MD5 Stream are organized into topic(s).

Method

StringcomputeMD5(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();
...
StringcomputeMd5(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);
...
StringcomputeMD5(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());
StringcomputeMD5checksum(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);
