Method Details

byteArrayToBase64

public static String byteArrayToBase64(byte[] a)

Translates the specified byte array into a Base64 string as per Preferences.put(byte[]).

byteArrayToAltBase64

public static String byteArrayToAltBase64(byte[] a)

Translates the specified byte array into an "alternate representation" Base64 string. This non-standard variant uses an alphabet that does not contain the uppercase alphabetic characters, which makes it suitable for use in situations where case-folding occurs.

base64ToByteArray

public static byte[] base64ToByteArray(String s)

Translates the specified Base64 string (as per Preferences.get(byte[])) into a byte array.

altBase64ToByteArray

public static byte[] altBase64ToByteArray(String s)

Translates the specified "alternate representation" Base64 string into a byte array.
