From 760b77592c0896b57fefbfbc4a77d22b1ad78cfb Mon Sep 17 00:00:00 2001 From: agc Date: Fri, 13 Aug 2004 10:26:03 +0000 Subject: Initial import of hydan-0.13 into the Packages Collection. Hydan steganographically conceals a message into an application. It exploits redundancy in the i386 instruction set by defining sets of functionally equivalent instructions. It then encodes information in machine code by using the appropriate instructions from each set. Features: - Application filesize remains unchanged - Message is blowfish encrypted with a user-supplied passphrase before being embedded - Encoding rate: 1/110 Primary uses for Hydan: - Covert Communication: embedding data into binaries creates a covert channel that can be used to exchange secret messages. - Signing: a program's cryptographic signature can be embedded into itself. The recipient of the binary can then verify that it has not been tampered with (virus or trojan), and is really from who it claims to be from. This check can be built into the OS for user transparency. - Watermarking: a watermark can be embedded to uniquely identify binaries for copyright purposes, or as part of a DRM scheme. Note: this usage is not recommended as Hydan implements fragile watermarks. --- security/hydan/PLIST | 7 +++++++ 1 file changed, 7 insertions(+) create mode 100644 security/hydan/PLIST (limited to 'security/hydan/PLIST') diff --git a/security/hydan/PLIST b/security/hydan/PLIST new file mode 100644 index 00000000000..75106941b39 --- /dev/null +++ b/security/hydan/PLIST @@ -0,0 +1,7 @@ +@comment $NetBSD: PLIST,v 1.1.1.1 2004/08/13 10:26:03 agc Exp $ +bin/hydan +bin/hydan-decode +bin/hydan-stats +share/hydan/README.details +share/hydan/README +@dirrm share/hydan -- cgit v1.2.3
