Method Detail

toString

public static java.lang.String toString(byte[] b)

Convert binary data to a base64-encoded String

Parameters:

b - An array containing binary data

Returns:

A String containing the encoded data

toString

public static java.lang.String toString(byte[] b,
                                        boolean useUrl)

Convert binary data to a base64-encoded String

Parameters:

b - An array containing binary data

useUrl - True to use Base64URL encoding (i.e. no trailing =, -_ instead of +/)

Returns:

A String containing the encoded data

formatString

public static java.lang.String formatString(byte[] b,
                                            int lineLength,
                                            java.lang.String prefix,
                                            boolean addClose)

Formats data into a nicely formatted base64 encoded String

Parameters:

b - An array containing binary data

lineLength - The number of characters per line

prefix - A string prefixing the characters on each line

addClose - Whether to add a close parenthesis or not

Returns:

A String representing the formatted output

fromString

public static byte[] fromString(java.lang.String str)

Convert a base64-encoded String to binary data

Parameters:

str - A String containing the encoded data

Returns:

An array containing the binary data, or null if the string is invalid
