- Method Detail
  - 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.
