Open Source Java Text Editors

UPDATE 2024: Get a new version here: https://github.com/ivoras/EncryptedNotepad2 "Encrypted Notepad" does only one thing, but aims to do it perfectly - a Notepad-like simple text editor where files are saved (and later loaded) encrypted with industrial strength algorithms. Available both for the desktop (as a Java application) and on Android. Unencrypted data is never stored on-disk. Source is released (on SourceForge) under the BSD license.

AESTextCrypt is an easy-to-use open source tool for text encryption and decryption. Primarily intended for use with email, use it wherever you need to protect text from prying eyes. The encrypted text can be copy/pasted into any text-handling application (e.g. email) instead of plain text. Convenience buttons are provided for clipboard operations. AESTextCrypt uses AES-256 bit encryption which is the strongest available encryption scheme. It also employs bcrypt, which implements key-stretching and an adaptive key setup phase, the complexity (number of rounds) of which is automatically set to match the processing power of the encrypting computer. This makes it highly resistant to dictionary attack. AESTextCrypt is written in Java, so can be run on all desktop platforms - Windows, Mac and Linux.

TextConverter is a graphical text editor allowing the user to encrypt/decrypt the textual contents displayed on the screen using a 128-bit AES (Advanced Encryption Standard) cipher.

iBox is a powerful information management tools for Android, which gives you a safe and secure way to store all of your critical information. It could be credit card numbers, accounts, passwords, marketing plans, product ideas, minutes and much more.

PCSecrets is a PC application that holds secret text data - protected by a master password and strong encryption. Use it as a password manager or just somewhere to hold any text data securely in one place. It can hold a second, hidden set of secrets that is undetectable and plausibly deniable. The program is also a PC counterpart of the Secrets for Android app. It uses the same data structure and provides synchronization that allows easy transfer of secrets between the two. For those who find the personal computer environment more comfortable for data entry and editing (i.e. a real keyboard), PCSecrets provides an alternative way to manage your secrets. Sync is also effectively a form of backup. To enable the sync feature with Secrets for Android, you need to install the PCSecrets Sync app, downloadable from SourceForge or Google Play. PCSecrets import plus PCSecrets Sync provides a route to importing secret data into Secrets for Android that would not otherwise be possible.

Cygnus Editor is a basic text-editing program created entirly in Java. And it's most commonly used to view or edit text files (.txt). A text file is a file type typically identified by the .txt file name extension. In Cygnus Editor you can encrypt your text document, so nobody can see the content of your document. Also you can decrypt your document and edit it. Cygnus Editor uses AES-256 encryption. AES-256 is the most powerful encryption standard yet. AES-256 uses many applications, websites and networks to secure their data. And now you can secure your document with Cygnus Editor.

This is free Java desktop application to keep your note in safe from others using the Encrypting Decrypting symmetric key algorithm, it's easy to transfer your note form source to another in confidential manner.

Imagine being able to send an encrypted message as a single file to someone working on any Operating System, without them having to install any software to decrypt it. Just send them an Inkjar. Or you can store your own passwords on a usb key anywhere.

From the creator of ClipClear comes JClipClear, a Java version of the Clipboard displayer and clearer. This program works on almost all OSes that have a clipboard feature.

A Secure Diary Program written in Java and using the bouncycastle JCE Cryptograpic library. It uses a combination of BlowFish and TripleDES (XORed) to encrypt Diary entries.

MicroSafe is a J2ME 1.0 application to store and access notes in a hierarchical data structure (outline) on mobile devices (CLDC - Connected Limited Device Configuration). Notes can be encrypted to store data like PINs, passwords, etc. securely.

This is a diary that allows you to digitally write entries and view them. What makes this a masterpiece from its counterparts is how user data is created and abstracted. User data is protected and stored in PNG images, the image it self is not encrypted but the data inside the image is encrypted. If you open any one of the created PNG images, they look like blank images!. These "normal" looking images protect your information from prying eyes. The simplicity and elegance of my program stores your data(password and entry) locally and hidden from everyone.

Un programa para cambiar el orden de las palabras en una frase o las letras de una palabra u otros algoritmos. Su principal objetivo es cambiar las frases para hacerlas mas ilegibles o para aparentar ser más friki en tus conversaciones o por diversi

Twinkle is an open source text editor that saves the documents in an encrypted form.

jCryptPad stores text informationen hierarchical, e.g. passwords, important texts etc. The data is saved in a encrypted xml file. Encryption is done with the AES algorithm. Additionally a password generator and a text encryption editor is also included.

This project develops an application to provide PGP functionality (encrypting, decrypting, and verifying text and data using asymmetric keys as well as managing these keys) on devices supporting PersonalJava (eg. mobile phones like the SonyEricsson P800)
