Open Source Text Editors

sops is an editor of encrypted files that supports YAML, JSON, ENV, INI and BINARY formats and encrypts with AWS KMS, GCP KMS, Azure Key Vault, age, and PGP. For the adventurous, unstable features are available in the develop branch, which you can install from source. To use sops as a library, take a look at the decrypt package. We rewrote Sops in Go to solve a number of deployment issues, but the Python branch still exists under python-sops. We will keep maintaining it for a while, and you can still pip install sops, but we strongly recommend you use the Go version instead. If you're using AWS KMS, create one or multiple master keys in the IAM console and export them, comma separated, in the SOPS_KMS_ARN env variable. It is recommended to use at least two master keys in different regions. If you want to use PGP, export the fingerprints of the public keys, comma separated, in the SOPS_PGP_FP env variable.

Tabbed notebook with RichText editor, multi-level notes and strong encryption. This project is an evolution of Tranglos Keynote (of Marek Jedlinski), with new features like: - Unicode compliant - Improvement in image management - Improved Find All - Redesigned navigation history mechanism - New file format: compressed - Improved treatment of links, and new internal KNT links, vinculated to markers, not only to caret position - Improved Clipboard Capture / Web Clip - Alarms on nodes - New kind of virtual nodes: links to other nodes (Mirror nodes) - New button: 'Copy Format' - Improved Clipboard Capture / Web Clip - ...

Our site is created to collect in one place information about portable app development. We hope that people who need this information will find it on our site. We are not limited to one method of creating portable applications, we want to write about them all. If you know the methods that we don't have, let us know about them. And we will inform about them our visitors.

Store your most valuable notes in a LockNote. Hide your everyday notes in a safe place. Application and document in one: the mechanism to encrypt and decrypt a note is part of it. Secure, simple, independent. No installation required.

Tabbed notebook with RichText editor, multi-level notes and strong encryption

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.

An alternative to the string library for C and C++ which is more functional and does not have buffer overflow problems.

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.

The Arcanum Editor is a small but powerful tool to encrypt and decrypt messages. The program also comes with it's own format CTXT. This format is based on XML and allows you to save texts with the Advanced Encryption Standard.

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.

Mailcrypt is an Emacs Lisp package which provides a simple interface to public key cryptography with PGP [and now GnuPG!]. Mailcrypt makes strong cryptography a fully integrated part of your normal mail and news handling environment

Caditor is a portable tabbed text editor featuring encryption, syntax highlighting, autocomplete, line numbering and a functional plugin system.

Dear Diary is a password-protected text editor with features similar to WordPad that automatically encrypts the text before writing to disk. You can format text with different colors, fonts and font sizes as well as insert images into your documents.

Generate RSA key pairs of arbitrary length; convert text between formats or use keys to transform/crypt text. Supports decimal, hexadecimal, base64 and text input and output. Entirely ANSI C++; no external dependencies.

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.

CryptoFile is a RichEdit application that encrypt files, using the microsoft api crypt v2.0 - and a proprietary ASCII MIME functions. It associate the extension .pto to the crypt and thus enable you to create an encrypted text files out of the box.

MSLK provides the precompiled Win32 binaries of some excellent porject with a GPL or similar open source license. Here will keep updated.

Programm zur Analyse von Texten und reellen Zahlen. Texte/Zahlen können (mit versch. Optionen) zerlegt werden in einzelne Wörter, Buchstaben oder Ziffern.

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.

This program is used as a tool to check for ASCII code and strip it out to a new file to recover documents that got corrupted or find hidden data in viruses that contain text by the virus writer or spies puting comments in images or other files.

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.

JDS is a powerful tool for data protection. Documents are encrypted using a special algorithm. The data encryption algorithm is constantly updated to improve security. The program also provides other functions. Such as sending a file to a vault with password access, fast text encryption in 3 types, and much more. The program is easy to use and does not require special knowledge. The standard version has 2 languages (Russian and English) and 9 themes. You can download the language and theme pack separately.

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.
