Is Crypt::CBC with the Crypt::Blowfish algorithm safe for encrypting many plain text values with a single key value? I'm encrypting e-mail addresses for this application but don't know whether I'm doing things correctly or not. I recall hearing that it isn't safe to use the same key for multiple plaintexts with Crypt::RC4. So I'm just checking first.
# $self is a CGI::Application object
my $encrypted = encrypt_address(
address => $address,
key => $self -> param('encryption_key'),
cipher => $self -> param('encryption_cipher') );
....
sub encrypt_address {
my %arg = @_;
require Crypt::CBC;
Crypt::CBC -> new(
{ key => $arg{key},
cipher => $arg{cipher} } )
-> encrypt_hex( $arg{address} );
}

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).
