( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Ok! I will make it short. My post is about piping an email into a Perl script without fooling around with the local mailer definition of postfix (see the other post here). Basically my solution simulates the smrsh feature of sendmail. I do not intend to discuss more than this here.

The topic of email security is of an other order of magnitude. As stated you can only protect your emails by encrypting of the communication link like https. This is only available if you use IPV6.

Facts are security is matter of time and resources. With an infinite amount of time or infinite resources you can breach any security feature, even PGP.

Now to round up the case, to read the content of an encrypted email, you first capture it from the Net, for example with tcpdump. Next you write a program and you crack it.(dot) Depending on the encryption used, this may last several centuries. Of course you can make like EFF, that just created a machine dedicated to crack the DES encryption in 1998.(dot again)

If the communication link is not encrypted it will be pretty easy to capture interesting emails and to proceed with the above classical procedure. If the link is encrypted, it will be very difficult to find the mails your are looking for, potentially it will be impossible. (last dot)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
