in reply to perl2exe - no more secrets
The encryption algorithm in Perl2Exe has been improved. The current version does not use the xor method.
The reverse-engineering method posted on bugtrack does not actually work because it assumes the xor method. It only appears to work because it reads the expected answer from the original source.
Tools of this type are simply packagers, they don't guarantee any security of the source code or offer any speed increase.
Perl2Exe does offer some conveniences in the distribution of applications. Because Perl2Exe is multi-platform and cross-platform it makes it easier to create binary packages for multiple OS's from a single machine.
