Name CryptoStego
Ontology
Released 2016

CryptoStego by Jeffery (Zeyu) Zhao (zeruniverse) is a javascript library for steganography with encryption. It supports both LSB (PNG) and DCT (JPG) methods.

  • 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).
  • DCT mode offers various levels of robustness to compression/resizing/various other picture editing procedures.

Not all versions are backwards compatible

  • v1.8 - Valid bits and their order decided by Mersenne Twister PRNG, and seed generated using SHA512(password)
  • v1.6 - More flexible on which frequency bands to write data on frequency space, add support to CbCr downsampling
