./security/snow, Whitespace steganography program

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 20130616, Package name: snow-20130616, Maintainer: agc

Whitespace steganography

The program snow is used to conceal messages in ASCII text by
appending whitespace to the end of lines. Because spaces and tabs are
generally not visible in text viewers, the message is effectively
hidden from casual observers. And if the built-in encryption is used,
the message cannot be read even if it is detected.

What's in a name?

snow exploits the steganographic nature of whitespace. Locating
trailing whitespace in text is like finding a polar bear in a
snowstorm (which, by the way, explains the logo). And it uses the ICE
encryption algorithm, so the name is thematically consistent.

Add SHA512 digests for distfiles for security category

Problems found locating distfiles:

	Package uvscan: missing distfile vlp4510e.tar.Z

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.
