(10 replies) I'm using php on a shared server and have no control over the configuration. It does not seem to support mcrypt. Is there any other easy way to encrypt and decrypt a string with php?

Hp Laser Jet 4100 Driver. Dean Hall I'm faced with the same problem, as it seems PHP can't find the modules once they're compiled in. I was thinking, if I can't find a way around this, if you have openssl installed, you could use openssl on the command line, pipe the output to a file, and read it from there.

Or you could even use Perl on the command line. Use 'system()', I think. It's not the best way, but it's a workaround. ----- Original Message ----- From: 'Dave Jones' To: Sent: Sunday, August 20, 2000 6.25 pm Subject.

Dave Jones Nobody out there has any suggestion of how to encrypt and decrypt a string without mcrypt? I can't use md5() because I'm not comparing two things, I'm trying to pass a new string from page to page without it being readable.

It doesn't have to be extremely secure, it's not financial data, but it shouldn't be easy to decrypt by the casual user. And I don't have control over my configuration (which does not have mcrypt installed) so it has to be something I can create in php3. Hp 1200 Printer Driver For Windows 7 32 Bit here.

But one-time pads are only good once -- by definition, a one-time pad must be *truly* random, the same exact length as the plaintext, and only used once. If it doesn't meet any of these qualifications, it's not a one-time pad and is *not* good for encryption.

But, if you do need a one-time pad, it's unbreakable.:-) Really! Brian Huddleston And just to reiterate Dean's point. The numbers used to generate the pad must be truly random.

Vw T5 Transporter Bedienungsanleitung Pdf Printer. Otherwise your security begins and ends with how good your random number generator is.the usual answer being, not very. So you end up being not much better off than Rot13ing it. Use a real encryption algorhytm if you are serious about it at all.
