###### Geocaching Quick Search

In this section, you may search for a First To Find (FTF) by entering a state, province or country in the box and clicking the search button. It will open a new window showing geocaches sorted by "last found date" which will
give you FTF's first and then loneliest geocaches next. Not all locations on the Geocaching website are listed. If your area is not on here, reach out to me and I'll see if I can get it
added.

You may also see recently published caches near your current location. Because this uses your devices current location, you will need to grant browser location access in order to proceed.

**Note:** It may take a few seconds to locate your device. If you are on mobile, you may have to click the buttons twice.

Cipher Tools

**Additive Cipher**- Similar to a Caesar cipher, each character of the alphabet is assigned a value and a key number within the alphabet is chosen. Each character is added with this key number and the corresponding letter is substituted (mod 26).**ADFGX Cipher**- Tool to convert text using the ADFGX cipher and a custom alphabet.**ADFGVX Cipher**- Tool to convert text using the ADFGVX cipher and a custom alphabet.**Affine Cipher**- Tool to convert text using the Affine cipher and a custom alphabet.**Albam Cipher**- Simple substitution cipher that swaps letters in the alphabet with a different letter in a second alphabet. Similar to Atbash.**ASCII-85**- This coding system (AKA Base 85) was created by Adobe Systems and uses 5 ASCII characters to code 4 bytes similar to base64.**Atbash Cipher**- Tool to convert text into Atbash cipher which flips the text from A-Z to Z-A.**Autokey Cipher**- This cipher is a polyalphabetic substitution cipher.**Bacon Cipher**- Converts text Bacon Cipher. Able to decrypt A/B, 0/1, Uppercase/Lowercase, and Atbash style A-M/N-Z encryptions.**Beaufort Cipher**- This is a polyalphabetic substitution cipher that is similar to the Vigenère cipher, only that instead of adding letter values, it calculates the cipherletter by taking the keyletter minus the plaintextletter.**Variant Beaufort Cipher**- This is a polyalphabetic substitution cipher that is similar to the Vigenère cipher. The key differences is the encryption is performed like decryption in the Vigenère and decryption is performed like the encryption in the Vigenère.**Bifid Cipher**- This cipher combines the Polybius square with transposition and uses fractionation to achieve diffusion.**Burrows-Wheeler Transform**- The Burrows–Wheeler transform rearranges a character string into runs of similar characters. This is useful for compression and more importantly, the transformation is reversible, without needing to store any additional data except the position of the first original character.**Caesar Box Cipher**- The Caesar Box is a cipher that is based on a transposition method. The cipher is encrypted by writing the text in columns (padding with extra characters to make them even) and then reading off the text by rows. This is not a Caesar cipher.**Carbonaro Cipher**- Simple substitution cipher used by a secret society in Naples called the Carboneria. Similar to Atbash.**Chaocipher**- This encryption uses two rotating disks on which is written a custom alphabet. The two disks are identical and linked with a kind of gearing (ratio 1:1) that if a disk is turned clockwise, the other turns counter-clockwise.**Columnar Transposition Cipher**- This tool writes text out in rows based off of a keyword and then reads the text off in columns.**Double Transposition**- The double transposition cipher (AKA double columnar transposition) was used by military forces in World War I and II.

It is considered one of the most secure ciphers that can be performed by hand.**Enigma (M3) Cipher**- This Enigma tool is an accurate simulation of the M3 Enigma cipher machine used by the German Navy during the Second World War.**Foursquare Cipher**- This tool encrypts pairs of letters (like playfair) using four 5 by 5 matrices arranged in a square.**Fractionated Morse Cipher**- Converts plaintext to morse code and then enciphers fixed size blocks of morse back into letters. You can also use a keyword to further increase the security of the cipher.**Gronsfeld Cipher**- The Gronsfeld cipher is a polyalphabetic cipher (a series of Caesar ciphers) where the shift is determined by numbers. It is similar to the Vigenère cipher, but the key uses digits instead of letters.**Hill Cipher**- The Hill cipher is a polygraphic substitution cipher based on linear algebra. It uses matrices and matrix multiplication to encrypt/decrypt the text.**Kamasutra Cipher**- The Kamasutra (Vatsyayana) cipher is a simple substitution cipher where the 26 letters of the alphabet are organized into 13 pairs of characters.**Keyed Caesar Cipher**- The Keyed Caesar cipher is a variation to the standard Caesar cipher (shifting the letters by 13). In a keyed version, the alphabet is "keyed" by using a word and those letters are moved to the front of the alphabet and the rotation is performed.**Multiplicative Cipher**- In a Multiplicative cipher, each character of the alphabet is assigned a value and a coprime key to the length of the alphabet is chosen. Each character is multiplied with this key and the corresponding letter is substituted.**One Time Pad Cipher**- The one time pad is, theoretically, an unbreakable cipher. In order for it to work, a pre-shared key of the same length as the message must be shared with the intended recipient.**Pizzini Cipher**- The Pizzini cipher is very similar to the classic Caesar cipher where the alphabet is shifted three letters (A => D, B => E, etc). The difference is the Pizzini cipher assigns those letters to numbers so A = 4, etc.**Playfair Cipher**- This cipher encrypts pairs of letters (digraphs), instead of single letters as in the simple substitution cipher.**Porta Key Cipher**- This cipher is a polyalphabetic substitution cipher similar to the Vigenère. Where the Vigenère cipher uses 26 alphabets, the Porta only uses 13 alphabets.**Pollux Cipher**- This cipher is a super-encryption system based on Morse code and replaces the dots, dashes and space by alphanumeric characters. When encrypting, a corresponding character is randomly selected from the list of possibilities; therefore every encryption will be almost certainly be different each time.**Polybius Square Cipher**- This cipher is a polyalphabetic substitution cipher and is essentially identical to the simple substitution cipher, except that each plaintext character is enciphered as 2 ciphertext characters.**Qwerty Cipher**- This simple substitution cipher maps the keys of a QWERTY keyboard layout to letters like this: QWERTY = ABCDEF.**Rail Fence Cipher**- The railfence cipher is a transposition cipher that follows a simple rule for mixing up the characters in the plaintext to form the ciphertext.**Rotation/Caesar Cipher**- Also known as a caesar cipher, this allows you to rotate numbers (Rot 5), letters (Rot 13), letters and numbers (Rot 18), all ASCII characters (Rot 47), or show all rotations from 0 to 25 either encrypted or decrypted.**Rotation Grid**- The cipher takes text written in a grid, rotates them by 90° and reads the text back out.**Rotation Special**- This special version of the**Rot Cipher**takes a set of characters and rotates them each in incremental order where each character is rotated by +1 from the last rotation.**Route Transposition Cipher**- The route transposition cipher rearranges the plaintext letters based on a shape of an imaginary path drawn on a grid, which contains all the message letters.**Running Key Cipher**- This polyalphabetic substitution cipher has the same internal workings as the Vigenère cipher. The difference lies in how the key is chosen; the Vigenère cipher uses a short key that repeats, whereas the running key cipher uses a long key such as an excerpt from a book.**Scytale Cipher**- The Scytale is a cipher that is based on a transposition method. A stretch of leather with letters on it was wound upon a piece of wood with the correct diameter and the encoded message could then be read.**Straddle Checkerboard Cipher**- Substitution cipher using a variable length alphabet.**Substitution Cipher**- Allows you to create your own version of an alphabet as a substitution.**Trifid Cipher**- The Trifid cipher uses three tables to fractionate letters into trigrams, mixes the parts of the trigrams and then uses the table to convert the trigrams back to letters again.**Trithemius Cipher**- This cipher uses a tableau (tabula recta) to encrypt/decrypt a message. A custom alphabet can also be created to make it a little more secure.**Übchi Transposition Cipher**- The Übchi Transposition Cipher was used by the Germans during World War 1 and is a double columnar transposition cipher.**Vigenère Cipher**- The Vigenère Cipher is a polyalphabetic substitution cipher.
