17 | This is plain text steganography with zero-width characters of Unicode.
18 | Zero-width characters is inserted within the words.
19 |
20 | JavaScript library is below.
21 | http://330k.github.io/misc_tools/unicode_steganography.js
22 |
99 | encodeSteganography returns a stego String which is embedded steganography of Uint8Array.
100 |
101 |
unicodeSteganographer.decodeText(String)
102 |
103 | decodeSteganography returns a JavaScript Object: { originalText: original text (String), hiddenText: hidden text (String)}.
104 |
105 |
unicodeSteganographer.decodeBinary(String)
106 |
107 | decodeSteganography returns a JavaScript Object: { originalText: original text (String), hiddenData: hidden data (Uint8Array)}.
108 |
109 |
unicodeSteganographer.setUseChars(String)
110 |
111 | setUseChars sets the characters for steganography as a String.
112 | Default characters used for steganography are U+200C, U+200D, U+202C, and U+FEFF.
113 | U+200B(ZERO WIDTH SPACE) is deleted in Gmail when sending a mail from browsers.
