Method Detail

equals

public static boolean equals(byte[] a1,
                             int a1Offset,
                             byte[] a2,
                             int a2Offset,
                             int length)

Check whether some part or whole of two byte arrays is equal, for length bytes starting at some offset.

Parameters:

a1 -

a1Offset -

a2 -

a2Offset -

length -

Returns:

true or false

printHex

public static java.lang.String printHex(byte[] array,
                                        int offset,
                                        int len)

Get a hexadecimal representation of a byte array starting at offset index for len bytes, with each octet separated by a space.

Parameters:

array -

offset -

len -

Returns:

hex string, each octet delimited by a space

toHex

public static java.lang.String toHex(byte[] array)

Get the hexadecimal representation of a byte array.

Parameters:

array -

Returns:

hex string

toHex

public static java.lang.String toHex(byte[] array,
                                     int offset,
                                     int len)

Get the hexadecimal representation of a byte array starting at offset index for len bytes.

Parameters:

array -

offset -

len -

Returns:

hex string

parseHex

public static byte[] parseHex(java.lang.String hex)

encodeSensitiveStringToUtf8

public static byte[] encodeSensitiveStringToUtf8(char[] str)

Converts a char-array to UTF-8 byte-array and then blanks out source array and all intermediate arrays.

This is useful when a plaintext password needs to be encoded as UTF-8.

Parameters:

str - A not-null string as a character array.

Returns:

UTF-8 bytes of the string
