It supports both LSB ([[PNG]]) and DCT ([[JPG]]) methods.<br /> <br /> * Non-linear bit-by-bit message storage without any header. Built for absolute security (No signal for password error. Wrong password results in wrong message).<br /> * DCT mode offers various levels of robustness to compression/resizing/various other picture editing procedures.<br /> <br /> Not all versions are backwards compatible<br /> <br /> * v1.8 - Valid bits and their order decided by Mersenne Twister PRNG, and seed generated using SHA512(password)<br /> * v1.6 - More flexible on which frequency bands to write data on frequency space, add support to CbCr downsampling<br /> <br /> <br /> == Links ==<br /> * [https://github.com/zeruniverse/CryptoStego Github homepage]<br /> * [https://stego.js.org/ Online demonstration]</div>
