Welcome to Code Haven, a tool to practice K1, K2, K3, and random substitution Aristocrats, Patristocrats, and Xenocrypts for the Codebusters Science Olympiad event. The aim of this tool is to mimic a problem on a real Codebusters test as closely as possible (while still being convenient to use).

Note: Xenocrypts are English quotes translated into Spanish and may not always be accurate. Keyword alphabets will always encode with an English keyword

Note: Not compatible with mobile; requires a physical keyboard

To start solving a problem, select a letter by clicking the box under the ciphertext letter. Use the keyboard to type a letter, which will be entered for all instances of the selected letter. The selected element will then advance to the next empty letter.

Note: to type Ñ for Xenocrypts, press the ~ (tilde) key

Color	Meaning
	Currently selected element
	Same letter as the selected letter, but not the currently selected element
	Unselected letter

Once a problem has been completed, press the [Enter] or [Return] key. If the entered solution is correct, an alert will appear with the solution and the time taken to solve the problem.

There are five tools available in CodeHaven to make solving ciphers easier

Clicking the ciphertext letters (in gray) on any cipher will mark this letter in blue to more easily recognize repeating patterns, especially helpful for Patristocrats

Only for Patristocrats, clicking in between two letters will create a separation between these letters, signifying a break between words for increased readability

When autocheck is enabled by clicking the checkbox at the top, incorrect letters will be highlighted in red in both the cipher and the frequency table at the bottom

When the hint button is pressed, one correct letter will be inputted into the cipher, starting with vowels and followed by consonants in order of frequency in the English or Spanish language

When the reset button is pressed, the entire text of the cipher is removed, but marked patterns will remain
