    • hex

      public static String hex(byte[] theArray)
      Return the hex string value of the byte array
      Parameters:
      theArray - the input array
      Returns:
      the hex value of the bytes

    • md5

      public static byte[] md5(String theString)
      Returns the md5 representation of a string
      Parameters:
      theString - the string to md5
      Returns:
      the byte representation of the md5 sum of the string

    • md5

      public static byte[] md5(byte[] theBytes)
      Returns the md5 representation of a string
      Parameters:
      theBytes - the bytes to md5
      Returns:
      the byte representation of the md5 sum of the string

    • getRandomString

      public static String getRandomString(int theLength)
      Return a string of random characters of the specified length.
      Parameters:
      theLength - the size of the random string to create
      Returns:
      a string of random letters

    • getRandomString

      public static String getRandomString(int theLength, Random random)

    • urlEncode

      public static String urlEncode(String theString)
      URL encode the string using the UTF8 charset
      Parameters:
      theString - the string to encode
      Returns:
      the url encoded string

    • urlEncode

      public static String urlEncode(String theString, Charset theCharset)
      URL encode the given string using the given Charset
      Parameters:
      theString - the string to encode
      theCharset - the charset to encode the string using
      Returns:
      the string encoded with the given charset

    • urlDecode

      public static String urlDecode(String theString)
      URL decode the string using the UTF8 charset
      Parameters:
      theString - the string to decode
      Returns:

      Parameters:
      theString - the string to decode
      theCharset - the charset to decode the string using
      Returns:
      the string decoded with the given charset

    • base64Encode

      public static String base64Encode(byte[] theArrayToEncode)
      Base64 encodes the given byte array. This utility is provided to abstract over the Sun implementation which is deprecated and marked for deletion. The implementation of this method will always work; so if the existing Sun implementation goes away, this will be switched to an appropriate implementation without requiring any changes to dependant code.
      Parameters:
      theArrayToEncode - the bytes to encode
      Returns:
      the bytes base64 encoded

    • base64Decode

      public static byte[] base64Decode(String theStringToDecode) throws IOException
      Base64 encodes the given byte array. This utility is provided to abstract over the Sun implementation which is deprecated and marked for deletion. The implementation of this method will always work; so if the existing Sun implementation goes away, this will be switched to an appropriate implementation without requiring any changes to dependant code.
      Parameters:
      theStringToDecode - the string to decode
      Returns:
      the bytes base64 decoded
      Throws:
      IOException - throw if there is an error while decoding

    • withoutLastCharacter

      public static String withoutLastCharacter(String s)
      Returns the string that is one character shorter than the input string, without the last character. If empty String is given, IllegalArgumentException is thrown.

    • withoutTrailingSlash
