# Manual Encryption Revisited

## TL;DR

This paper reviews manual encryption techniques, introduces new algorithms and ciphers including permutation, Spirale, Diagonales, and Carousel, and addresses key and password creation challenges.

## Contribution

It presents new manual encryption algorithms and solutions for key generation, enhancing traditional cipher methods.

## Key findings

- Introduced Spirale, a one-time-pad cipher
- Developed new transposition ciphers Diagonales and Carousel
- Provided solutions for key and password creation

## Abstract

This document brings together several articles devoted to manual encryption and introduces new algorithms and ciphers: a permutation algorithm, Spirale (a one-time-pad cipher), a solution to the problem of the ordered route of a table, Diagonales (a cipher by transposition), Carousel (another cipher by transposition), solutions to the problem of creating keys or passwords.
