Crypt::Memfrob - memfrob implementation in pure Perl

NAME

Crypt::Memfrob - memfrob implementation in pure Perl

SYNOPSIS

  use Crypt::Memfrob 'memfrob';
  my $frobed = memfrob($str);

DESCRIPTION

This package provides one function 'memfrob.' This is equivalent to the memfrob function included in glibc. With this library, you can generate glibc-compatible frobnicated (encrypted) strings, and defrobnicate glibc-generated strings, in Perl.

FUNCTIONS

memfrob: This function frobnicates given string and returns the result.

FROBNICATION

This library is based on GNU libc 2.2.4. From memfrob(3):

   The memfrob() function encrypts the first n bytes of the
   memory areas by exclusive-ORing each character with the
   number 42.  The effect can be reversed by using memfrob()
   on the encrypted memory area.

   Note that this function is not a proper encryption routine
   as the XOR constant is fixed, and is only suitable for
   hiding strings.
