pkgsrc/security/hydan, branch pkgsrc_2008Q2 [no description] https://git.osdyson.ru/mirror/pkgsrc/atom?h=pkgsrc_2008Q2 2006-03-04T21:28:51Z Point MAINTAINER to pkgsrc-users@NetBSD.org in the case where no 2006-03-04T21:28:51Z jlam jlam 2006-03-04T21:28:51Z urn:sha1:48ff096d36ac47701672a4f682e7c4ebafea1eb9 developer is officially maintaining the package. The rationale for changing this from "tech-pkg" to "pkgsrc-users" is that it implies that any user can try to maintain the package (by submitting patches to the mailing list). Since the folks most likely to care about the package are the folks that want to use it or are already using it, this would leverage the energy of users who aren't developers. Create directories before installing files into them. 2005-06-17T03:50:19Z jlam jlam 2005-06-17T03:50:19Z urn:sha1:f7a31a0cbc0ecfc696537d41c2c5bf92b2bac14c Add RMD160 digests. 2005-02-24T12:51:41Z agc agc 2005-02-24T12:51:41Z urn:sha1:2eb256146fa3337f8d832db9d8f9f3f5f1978821 Add patches to work around compile problems for this package on 2004-09-16T16:12:57Z he he 2004-09-16T16:12:57Z urn:sha1:66dfb6e4a54623f5f902fd1864a423f5f80544a1 NetBSD-1.6.2_STABLE. Gets rid of a parse error when only one argument is given to HDN_WARN, which leaves us with "fprintf(fp, arg, )". This may be a failure of the compiler on this platform to properly do varargs macros, but the changes are noops and gets it building there. Initial import of hydan-0.13 into the Packages Collection. 2004-08-13T10:26:03Z agc agc 2004-08-13T10:26:03Z urn:sha1:760b77592c0896b57fefbfbc4a77d22b1ad78cfb 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.
