Cipher Codes generally substitute different length strings of characters in the output, whilst ciphers generally substitute the same number of characters as are input. There are exceptions and some cipher systems may use slightly more, or fewer, characters when output versus the number that were input. Codes operated by substituting according to a large codebook which linked a random string of characters or numbers to a word or phrase. Most modern ciphers can be categorized in several ways By whether they work on blocks of symbols usually of a fixed size (block ciphers), or on a continuous stream of symbols (stream ciphers).By whether the same key is used for both encryption and decryption (symmetric key algorithms), or if a different key is used for each (asymmetric key algorithms). Etymology[edit] "Cipher" is alternatively spelled "cypher"; similarly "ciphertext" and "cyphertext", and so forth. "The concept of zero, called sifr in Arabic, came to medieval Europe from the Arabs.

Pict-O-Caches | Trip's GeoAdventures If there was ever a cache that everyone should try once, pict-o-caches would likely be near the top of the list. They take aspects of several different types of caches and join them together to make a cache that everyone can participate in and enjoy. But how do they work? First, we need to establish what they are… Pict-o-caches are a class on their own. Let’s look a bit closer. Obviously, this image shows a brick wall, so you would want to scan for brick buildings. Examining the photo, you at least now that it is near a window. Now, you can be certain that this is the corner of a building, and along the roof. This is the overall idea of this type of pict-o-cache. But I said that this the above method is just one type of this style of puzzle cache. I have not actually gone after one of this method. Either method provides an interesting caching experience. First, decide which method you want to us. However, for the first option, there’s a bit more that goes into preparing this. Like this:

The sculptures feature the same carved symbol and come with a riddle attached. Despite CCTV film showing a man leaving three heads outside a post office, their origin remains unknown. So far, 12 have appeared in Goathland and Kilburn, North Yorkshire; four in Arthington, West Yorkshire and three in Braithwell in South Yorkshire. Each of the heads, which are up to a foot tall, looks different but all feature the same carving - which appears to spell out the word "paradox" - and a note bearing the riddle: "Twinkle twinkle like a star does love blaze less from afar?" The villages they have been found in are up to 50 miles from each other. Mike and Valerie Hoyes, who run a post office in Braithwell, found three heads outside their business on the morning of 23 August. Mrs Hoyes said: "It's very weird. Stonemasons quizzed

Hieroglyphics Translator ― LingoJam This is an Egyptian hieroglyphics translator. Put your English text in the first box and it'll do it's best to translate it to Egyptian hieroglyphics in the output box. Important Notes A few important things that you should be aware of regarding this hieroglyphics translator: Firstly, this translator does a phonetic translation (or more accurately, transliteration). Which represents a cluster of three consonants: "nfr" (which was the sound of the Egyptian word for "good, beautiful, perfect"). The word "nfr" also gives you a clue about another aspect of the ancient Egyptian writing system: very few vowel sounds are included in written words. I've tried to make this translator as accurate as possible, but it's a work in progress (please let me know if you spot errors!). Another important note is that spaces and punctuation weren't a thing in the Egyptian hierglyphic system. Also, the reading direction varies across the historical corpus, but right-to-left was the most common. Thanks

I identified the picture almost at once but could not see in which of the three directions it might go. And I knew that I had to find out!” “This should come with a warning label on it. ...It's highly additive. “I took it to Rome with me and sought inspiration in the Forum.... ................. aaaagh, there's no escaping the clutches of the Runes!” “It took three pages before I was fully sold on this. “What I have enjoyed is the step-by-step developments of the first few pages leading into the greater challenges as you realise that there is more to each puzzle than you were first led to think - and the buzz of discovery when you realise how it actually works.” ”This is one of the most complex puzzles I have ever encountered. “I am proud to say that I have had my first Eureka moment when everything just slotted into place. “I’m totally intrigued with this puzzle.
