gnu.java.zrtp.utils.EmojiBase32

public class EmojiBase32
extends Object

Implements the base32 Emoji functions. Some technical details: - add a new SAS algorithm to the ZRTP library that uses 32 Unicode code points instead of 32 ASCII characters. - select 32 emojis that are easily distinguishable, known to everyone, not offending etc, using standard Unicode code points - select colored emojis that look good on white and on black backgrounds (many emojis look good on white only) - select emojis that are available on iOS, Android, Mac OS X (Windows?) I used the information on this Unicode page http://unicode.org/emoji/charts/full-emoji-list.html Created by werner on 30.12.15.
