In cryptography, DEAL (Data Encryption Algorithm with Larger blocks) is a symmetric block cipher derived from the Data Encryption Standard (DES). The design was proposed in a report by Lars Knudsen in 1998, and was submitted to the AES contest by Richard Outerbridge (who notes that Knudsen had presented the design at the SAC conference in 1997).
DEAL is a Feistel network which uses DES as the round function. It has a 128-bit block size and a variable key size of either 128, 192, or 256 bits. For key sizes of 128 and 192 bits, the cipher uses 6 rounds, increasing to 8 for the 256-bits size. The scheme has a comparable performance to Triple DES, and was relatively slow compared to many other AES candidates.
Hi. I have a kitchen mixer tap unit with older washer type inserts which has a dripping cold side. I have a pair of replacement ceramic inserts to upgrade both but the cold side insert will not shift at all. It genuinely is so tight that I am in danger of damaging the mounting even though I am...
Hello,
I've had unfortunate issues throughout my adult life and more so since switching to a largely plant based diet of blocking toilets.
Across multiple houses I've run into issues with it so I don't think it's one toilet specific, it's just me. I seem to produce a lot of poo!
While it...
Hi all. I recently ordered two separate water filtration systems (the cartridge type) from a local plumbing company. For both installs the pipe size is 3/4". For one of the systems they sent me 1" inlet filters, so I'll need to add a 3/4" to 1" adapter. And for the other install they sent me...
My brother is after a combi and asked me to look around for him. He's leaning towards either Intergas or Vaillant, Intergas being his first choice but thinks their prices might be beyond his budget of £800-£900. Found this one but seeing as I've not fitted boilers in years I've kind of lost...
Hi,
As some of you are aware, I am currently stuck in Italy running a shop that has nothing to do with plumbing :(
Yesterday I thought I'd got most of what I needed to get done by lunchtime and was able to take the rest of the day 'off' (which actually means try to get done the things that are...
I am thinking of moving the washing machine and tumble dryer to the cellar to create space in the kitchen.
The cellar ceiling is abou 2 ft above ground level - there is a window.
Now there is a water pipe so getting a connection for that shouldn't be an issue.
The cellar runs below the...

Is there a "typical" interval for doing a powerflush?
Reason for asking is that it was mentioned on a recent visit by "ServeHome".
I couldn't swear to it, but I'm sure that when it was done previously I was told that I only needed it to be done once.
History: All in 2009.
New Boiler...
Dewalt 18 volt brushless combi and 2 of 3.0 Ah batteries for £129.99 inc vat on Screwfix deal of day.
Seems good price considering you get 2 batteries.
Perhaps not a fully Pro drill, but might be of interest for those on a budget.
Hello,
I've just had my sink unclogged and my tap heads replaced and the total cost of this was £152 for the whole thing.
I would like to know if this is the normal price or if I've made a bad deal.
Fears grow as lack of toilet duck and drain cleaner because of brexit. Irish students are now working on alternative methods of unblocking a toilet. This is the low Nox version. Still in early stages of development. Lol
The customer dosen't want to change the cast iron bath but it has rust around the plug waste hole. It dosent look good and is difficult to clean.
I've suggested touching up the bath with some repair enamel paint but now am not sure which product to use. Some of the product reviews are not good...

Hi all,
I went to a property today to install a new Range cooker. There was already a Range there but this one has a gas oven instead of an electric oven. There's also a 28KW combi boiler and a 4ish KW gas fire there too.
On commissioning the cooker, the working pressure was about 14mB with...
