crypt::ideas

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I have a form that saves sensitive data to the drive on the web server. I would like to encrypt this and allow viewers to de-crypt the file. Does anyone have an implementation of crypt::ideas I could look at as an example? The ISP is not supporting PGP until September. Thanks in advance, Sean

I assume you mean Crypt::IDEA: Perldoc Crypt::IDEA .... my $key = pack("H32", "0123456789ABCDEF0123456789ABCDEF"); my $cipher = new IDEA $key; my $ciphertext = $cipher->encrypt("plaintex"); # NB - 8 bytes print unpack("H16", $ciphertext), "\n"; However, this can not be used to encrypt the data between your webserver and the browser. If you want to do that you'll need to be running an SSL webserver.	[reply]

Crypt::IDEA

Perldoc Crypt::IDEA

....
my $key = pack("H32", "0123456789ABCDEF0123456789ABCDEF");
my $cipher = new IDEA $key;
my $ciphertext = $cipher->encrypt("plaintex");  # NB - 8 bytes
print unpack("H16", $ciphertext), "\n";

However, this can not be used to encrypt the data between your webserver and the browser. If you want to do that you'll need to be running an SSL webserver.
