This is a very simple project with a Ascii85/Base85 codec (decoder & encoder). The version most similar to what is implemented is the Adobe Version.

This codec supports:

  1. using u to pad the last block
  2. using z as a short form for all-zero group

In Ascii85-encoded blocks, whitespace and line-break characters may be present anywhere, including in the middle of a 5-character block, but they must be silently ignored.

Ascii85, also called Base85, is a form of binary-to-text encoding developed by Paul E. Rutter for the btoa utility. By using five ASCII characters to represent four bytes of binary data (making the encoded size ¹⁄₄ larger than the original, assuming eight bits per ASCII character), it is more efficient than uuencode or Base64, which use four characters to represent three bytes of data (¹⁄₃ increase, assuming eight bits per ASCII character).

There are some included test cases that use the example given in the wiki link above.

    @Test
    public void basicWikiDecodeTest() {
        String encodedString = "9jqo^BlbD-BleB1DJ+*+F(f,q/0JhKF<GL>Cj@.4Gp$d7F!,L7@<6@)/0JDEF<G%<+EV:2F!," +
                "O<DJ+*.@<*K0@<6L(Df-\\0Ec5e;DffZ(EZee.Bl.9pF\"AGXBPCsi+DGm>@3BB/F*&OCAfu2/AKY" +
                "i(DIb:@FD,*)+C]U=@3BN#EcYf8ATD3s@q?d$AftVqCh[NqF<G:8+EV:.+Cf>-FD5W8ARlolDIa" +
                "l(DId<j@<?3r@:F%a+D58'ATD4$Bl@l3De:,-DJs`8ARoFb/0JMK@qB4^F!,R<AKZ&-DfTqBG%G" +
                ">uD.RTpAKYo'+CT/5+Cei#DII?(E,9)oF*2M7/c";

        String solution = "Man is distinguished, not only by his reason, but by this singular passion from other animals, "+
                "which is a lust of the mind, that by a perseverance of delight in the continued and indefatigable generation "+
                "of knowledge, exceeds the short vehemence of any carnal pleasure.";
        assertThat(solution, is(new String(Ascii85.decode(encodedString), StandardCharsets.US_ASCII)));
    }
