Free tools and resources helping you solve CTFs, ciphers, logic puzzles and room escape games. Classic Ciphers In cryptography, a cipher (or cypher) is a method for protecting data through encryption and decryption. Most ciphers require a specific key for encryption and decryption, but some ciphers like the ROT13 or Atbash ciphers have fixed keys. Many of the ciphers listed here were for military or other significant use during an earlier time, but today mostly are used only by puzzle makers. Text and Word Tools Wordplay and witty texts is one of the oldest forms of puzzles. Anagrams have been traced to the time of the Ancient Greeks, and they still are popular in modern brain teasers. Synonyms are common not only in crosswords, but plays a role in a wider range of puzzles. This section also contains text processing tools, which are useful for reversing, changing case, etc of texts. These tools will help you identify the types of encodings and ciphers used. Modern Ciphers Modern encryption methods can be divided by the key type and their operation on input data. Symmetric key algorithms use the same key for encryption and decryption (private key cryptography). Asymmetric key algorithms use different keys for encryption and decryption (public key cryptography). With symmetric keys, the sender and receiver must have agreed upon a key in advance, while with asymmetric keys anyone can send messages to the receiver. Also depending on their operation, ciphers are either block ciphers (encrypting a fixed block size) or stream ciphers (encrypting a continuous stream of data). Steganography While encryption protects information from being understood, an even higher protection would be if the information is hidden. The word steganography comes from the Greek word "steganos", meaning concealed, and "graphein", meaning writing. Modern steganography can hide information in images and audio files. Also information can be manually hidden in images through the use of very low contrast colors or metadata. Encodings Computers and digital devices need to represent letters in appropriate ways. ASCII codes are very common for storing texts, but with the demand to support more non-English texts,

Please let me know what you think of it and keep the hacker spirit high by writing code for every piece of hardware that you own! Public-Key Cryptography is a truly magical thing and I often wonder why we don’t use it more often. We go on and complain about how it is too easy for government agencies to look into our digital lives, while we do have all the tools to prevent it. Only we don’t use them and we don’t seem to ask facebook, gmail and so on to use them – not that they would. The funny part is that it would not require a lot of effort, because computers could automatically do all of that stuff in the background. All that would be needed is that we were able to securely store one, long password (the private key).In a nutshell public-key cryptography is a mathematical concept that allows us to encrypt a message that is intended to be read by just one person and to sign something to guarantee that it really came from you.Let’s take a closer look: public-key cryptography is based on a pair of keys, lets call them #1 and #2. When one uses key #1 to encrypt a message one can only decrypt it again using key #2. The same is true for a message encrypted. Download Cryptography Tools for free.
