• AES-256 encrypted with optional BZ2 compression.
  • Multi-round password hashing to derive key material from passwords.
  • No predictable patterns to search for. Offset is derived from the password, and the stride between pixels is arhythmic, with a seed value derived from the password.
  • Each color is treated as a discrete channel, with messages able to span channels. This allows up to three independent messages to be overlaid on the same carrier, or one message can occupy multiple channels.
  • Option for automatic re-scaling of the carrier image to minimize waste.
  • All relevant parameters are derived from the key, or stored as discrete bits, allowing for simple decoding. Just supply a carrier image and a correct password.
  • MD5 integrity verification.
  • File storage and retrieval
  • Built-in trivial logging faculty.
