Method Detail

encodeHex

public static char[] encodeHex(String data)

Transform the given String into an array of characters representing the hexadecimal values of each byte in order.

Parameters:

data - the byte array

Returns:

the resulted char array of the transformation.

encodeHex

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

Transform the given array of bytes into an array of characters representing the hexadecimal values of each byte in order.

Parameters:

data - the byte array

Returns:

the resulted char array of the transformation.

encodeHex

public static char[] encodeHex(byte[] data,
                               boolean lowerCase)

Transform the given array of bytes into an array of characters representing the hexadecimal values of each byte in order.

Parameters:

data - the byte array

lowerCase - the flag if the result shell be transform in lower case. If true the result is lowercase otherwise uppercase.

Returns:

the resulted char array of the transformation.

decodeHex

public static byte[] decodeHex(char[] data)
                        throws org.apache.commons.codec.DecoderException

Transform the given array of characters representing hexadecimal values into an array of bytes.

Parameters:

data - the array of characters

Returns:

A byte array that contains the binary data decoded from the given char array.

Throws:

org.apache.commons.codec.DecoderException - is thrown if an odd number or illegal of characters is supplied

decodeHex

public static String decodeHex(byte[] data)

Transform the given byte array that contains the binary data decoded to a String object. The given byte array comes usually from the decodeHex(char[]) method.

Parameters:

data - the given byte array that contains the binary data decoded

Returns:

the decoded string

decodeHexToString

public static String decodeHexToString(char[] data)
                                throws org.apache.commons.codec.DecoderException

Transform the given array of characters representing hexadecimal values into a String object.

Parameters:

data - the array of characters

Returns:

the decoded string

Throws:

org.apache.commons.codec.DecoderException - is thrown if an odd number or illegal of characters is supplied

toHex

public static char toHex(int i)

Transform the given int to a hexadecimal value.

Parameters:

i - the integer value to transform

Returns:

the char as a hexadecimal value.
