Security - Encryption/Decryption (25)

Eclipse quickly encrypts/decrypt text, useful for adding security to instant messaging and email conversations. A customizable hotkey system (by default Ctrl+Shift+E) works on highlighted text to copy encrypted text to the clipboard after prompting for a password. Secure text can then be pasted into any editor or application and then decrypted via the same method.

The program is an interface for a command-line utility called MySecret, which uses the Blowfish encryption algorithm. Eclipse is written in AutoHotkey.

Password Tech is a suite of security tools, including a strong random password and data file generator, text encryption tool, and master password generator.

• Random number generator - Create lists of random characters or passphrases from word lists. Includes multiple features to select easy-to-remember passwords that still conform to security standards.
  
• Text encryption - Uses the Windows clipboard (copy and paste) to encrypt text via hotkey. Also enables caching the password temporarily so you don't have to re-enter the password repeatedly.
  
• Master password - Rather than storing a specific password, the program generates the same password everytime. This is created via a master and perimeter words (e.g. service + email) to generate a high security password.

VeraCrypt is volume encryption software that functions like an attached drive, making it possible to actively work with data like any other drive until the volume is dismounted. The program supports favorites, hot keys, hardware acceleration, and auto-mount options. Includes a variety of available tools for added security including keyfiles, security tokens, hidden volumes, auto-dismount, cascaded encryption and cached password management.

Cross-platform with clients available for Mac and Linux. Alternatively, VeraCrypt Portable is also available.

VeraCrypt is based on the inactive TrueCrypt, attempting to solve some of the program's documented weaknesses. The program can open and convert TrueCrypt volumes.

LockNote works in two ways: it is a notepad that encrypts everything you put inside and also creates copies of itself when you drag-drop a text file into it. You end up with a new EXE that displays the content of that text file when run using the correct password.

TrueCrypt creates and opens secure volumes that function like an attached drive, making it possible to move files to and from a secure place, as well as open and run. Additional security features include support for key files and hidden volumes inside regular ones (for plausible deniability) for higher security, as well as hardware acceleration and benchmark tools for speed.

Supports a range of encryption algorithms including AES, Serpent, and Twofish, as well as combinations (e.g. Serpent + Twofish) in the event that one of them is eventually cracked.

Note: This program may have unfixed security vulnerabilities.  As version 7.2 only allows the opening of TrueCrypt volumes, not their creation, we are linking to a mirrror of Version 7.1a.

ClipSecure is a simple text and file encryption utility that uses automatic compression and many industry-standard algorithms, including AES. The text encryption operates within the Windows clipboard, and therefore can be used within any text-based program and most email clients. File encryption includes file wipe capability and is intended primarily for files under 10 megs.

FreeOTFE, named for "on-the-fly disk encryption" creates one or more encrypted virtual disks using numerous available encryption algorithms (e.g. AES, Twofish, Serpent, and many more), and can be used to encrypt entire partitions. A separate application that doesn't require administrative rights called FreeOTFE Explorer is also available from the same site, using an Explorer-like interface (see version comparison).

64-bit users: FreeOTFE Explorer is functional, but Windows 7 64-bit users cannot use FreeOTFE as the drivers are unsigned.

Note: On startup, you will receive a message asking you to use portable mode drivers to start the virtual disk drivers (you need administrator rights to do this, otherwise the menu item will be grayed out). When you shutdown the program, you will also be given the option to stop the virtual disk drivers.

CryptoTE is a feature-rich, tabbed secure notepad program that uses the powerful and easy to use Scintilla text editing widget, the same as used by Notepad++. Security features include integrated compression, automatic backup, auto-close after periods of inactivity, password generator, and the Serpent encryption algorithm. Notepad features include fast Find interface, multi-level undo, and insert date/time.

Linux version included. Container can include binary files as well as text.

NOTE: This project is outdated and may be insecure or incompatible with more recent versions of GPG.

gpg4usb is a basic, tabbed notepad tool with easy-to-use text and file encryption tools. Using the Gnu Privacy Guard (GPG) security system means you can exchange encrypted text and files with someone you've never met, where most programs require a communicated password. Additionally, users can digitally "sign" and verify information to help establish integrity, ownership, or agreement.

Users need only exchange a "public key" with one another in order to communicate. New users will need to generate a key, while users of other compatible software can import their existing keys.

Functional in Linux (see How to Extract). GPG is a compatible, open source alternative to the former commercial corporation PGP.

Crypto Notepad is a simple, notepad-like text editor that encrypts saved files. Other features include font and color customization, word wrap, shortcut keys, and auto-lock on minimize. You can press the lock icon to hide information without closing the application (will switch to a password prompt).

Utilizes the AES encryption algorithm with available 128, 192, and 256 key sizes.

MAXA Crypt Mobile allows anyone to easily encrypt files, directory trees, and text. Multiple files can be encrypted and compressed into a single file. Uses the 256-bit AES algorithm.

Adware note: the program shows an "about" page at startup with advertisements for other MAXA tools.

MAXA Text-2-EXE is a self-contained encrypted notes program allowing you to hide secure information such as serial numbers, passwords, phone numbers, etc. The program interface is a normal text editor with the added ability to save to an encrypted file. No program is necessary to open the file as each file is saved as an executable file, eliminating the need for an external viewer.

Adware note: the program shows an "about" page at startup with advertisements for other MAXA tools.

Claims use of AES 256-bit encryption.

Blowfish Advanced CS is a easy to use encryption and disk wipe program, removing the extra step of typing in a password every time you view an encrypted file. Instead, the program caches the key and allows the dynamic viewing of encrypted files, renamed to a .BFA extension. To view, open them inside the Blowfish Advanced CS file manager or drag-and-drop them into the program window. Note that edits are not dynamically encrypted to the same location. Files must be decrypted and then edited.

The program includes a variety of security options including use of a key disk, a time-out for available decryption, multiple algorithms including Blowfish (default), AES, Twofish, Serpent, etc., multiple file / empty disk space shredding options, and more. Compression options are also available.

VaultPad is a simple text and file encryptor. The program can take text, attachments, or both to create an easy-to-share XML file for storage or sharing.

The program uses AES cipher (symmetric-key pairs) to encrypt local messages and RSA/AES cipher (public/private key pairs) for shared messages. A SHA-512 cipher is used to hash passwords, so they aren't stored in the application itself. A MD5 algorithm is used to check embedded files for corruption. VaultPad will handle third party public keys to be able to encrypt/decrypt their files directly.

PicoCrypt is a small and fast encryption utility that uses Blowfish encryption algorithm in CBC mode. It is easy to use and supports multiple files drag-and-drop for encryption/decryption.

removableTrezor creates an encrypted data store (a so-called vault or trezor). These password protected stores may be stored in several places (located on several discs, or even several computers). It is a one-user application, and may only be run from one single computer.

ExcelPass easily adds password protection to Word, PowerPoint, Excel, PDF and ZIP files. The program supports drag-and-drop and can quickly encode one or more files to use standard security, meaning it can be opened by compatible viewers and editors, including Microsoft Office, LibreOffice, Adobe Acrobat, and many more. Both read and write protection are available (excluding ZIP files, which do not support write restrictions).

The program can also disable security via the same interface (click the unlock button). Functional in 64-bit.

NOTE: May not work with more recent versions of Windows 10.

Crypditor is a tabbed text editor that encrypts what you write. It is designed to store sensitive information such as PINs, serial numbers, passwords etc. The encrypted data is stored together with the EXE file itself, so launching the program will load the information directly after entering password.

Uses the AES encryption algorithm.

SteganoG hides an encrypted file inside a image file (BMP or RAW) and acts as a carrier. Also known as steganography, the program offers a variety of encryption algorithms including Blowfish, TEA, and Twofish.

Note that the included Skipjack and RC4 algorithms have known weaknesses.
