Method Details

getMD5Hash

public static char[] getMD5Hash(char[] msg)

Generate MD5 hash in a hex character representation

Parameters:

msg - message text

Returns:

hex hash value in text format

getSaltedMD5Hash

public static char[] getSaltedMD5Hash(char[] salt,
 char[] msg)

Generate salted MD5 hash for specified message. Supplied salt is returned as prefix to returned hash.

Parameters:

salt - digest salt (use empty string for no salt)

msg - message text

Returns:

salted hash using specified salt which is returned as a prefix to the hash

getSaltedMD5Hash

public static char[] getSaltedMD5Hash(char[] msg)

Generate salted MD5 hash for specified message using random salt. First 4-characters of returned hash correspond to the salt data.

Parameters:

msg - message text

Returns:

salted hash using randomly generated salt which is returned as a prefix to the hash

getMD5Hash

public static String getMD5Hash(InputStream in)
                         throws IOException

Generate MD5 message digest hash for specified input stream. Stream will be read until EOF is reached.

Parameters:

in - input stream

Returns:

message digest hash

Throws:

IOException - if reading input stream produces an error

getMD5Hash

public static String getMD5Hash(File file)
                         throws IOException

Generate MD5 message digest hash for specified file contents.

Parameters:

file - file to be read

Returns:

message digest hash

Throws:

IOException - if opening or reading file produces an error

getMD5Hash

public static String getMD5Hash(List<String> values)

Generate combined MD5 message digest hash for all values in the specified values list.

Parameters:

values - list of text strings

Returns:

MD5 message digest hash

hexDump

public static char[] hexDump(byte[] data)

Convert binary data to a sequence of hex characters.

Parameters:

data - binary data

Returns:

hex character representation of data
