Password Tech v3.5.4 Updated

  • 14MB (uncompressed)
  • Released on 15 Feb 2024
  • Suggested by I am Baas

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.

Includes available hotkeys, profiles, common password filter, and more.

ExcelPass 1.7.3.8

webfork on 4 Aug 2018
  • 4MB (uncompressed)
  • Released on 19 Feb 2017
  • Suggested by I am Baas

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.

Although there are a variety of other ways to add a password to Office and ZIP files, there is no PDF encryption component (either read or write) in the free versions of PDF-XChange, Foxit, and Adobe Acrobat. As a result, this is a very nice addition for PDF users.

spicydog on 2017-01-21 12:37

Works fine for zip and pdf files but nothing happens on xls(x) and doc(x) files :(

Am I missing something?

webfork on 2017-01-22 20:34

@spicydog: there is a known bug with creating a read-only password, which is being explored by the author. However, I just recently tested view without issue, and had no issues with DOCX or ZIP files. Files were generated with Office 2010 and 7zip. Please post in forums (or on the github page) if you keep having issues.

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

Does not seem to decrypt properly when using blowfish. I am unsure if it is the encrypt of decrypt side that is causing the issue. RC4 encryption works perfectly.

kiest on 2010-07-23 02:51

Does not encrypt/decrypt properly with all methods, but RC4 works fine. When CompressData is enabled, the decrypted file is smaller sized. When CompressData is disabled, the decrypted file seems to be the correct size but it is not the original file (checksum mismatch/content unreadable).

The website is live but no longer carries SteganoG, It can be downloaded at Softpedia.

gpg4usb v0.3.3-2

lwc on 5 May 2023
  • 29MB (uncompressed)
  • Released on 5 Jan 2016
  • Suggested by gpg4usb

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.

Hello,

In the last week we integrated 4 new languages.

@procyon: Thanks for the hint, we've put it on our bug list and already located the appropriate line in source, which causes this bug. So this will be fixed in the next release.

@mixture: We weren't sure, if we should integrate this, because it could confuse beginners, who read in other tutorials, that the should use the maximum keysize possible. Would be great, if you write your opinion to our mailing list. In fact we're not sure, if we should reduce the maximum key size again to 8192 (which is the maximum key size of any other gpg program We know).

@webfork: We've already integrated generation of RSA keys for the next release. So this will be possible soon. And the size of the DSA key is always 1024 bit (given by gpgme I think), the size of the EL Gamal subkey can be set higher...

gpg4usb on 2012-09-11 19:48

gpg4usb 0.3.2-1 released today!

0.3.2-1 generates safer gnupg-keys by default, with RSA and 1024bit minimum.
Including gpg binary was updated to version 1.4.12.

Bugfix:
Fix creation of empty Windows registry key on import from existing GnuPG

Have fun! http://gpg4usb.cpunk.de/

gpg4usb on 2014-08-20 20:22

New stable release 0.3.3-1

* gpg4usb-0.3.3-1 additionally contains a 64-bit linux binary now, so there's no need to have 32-bit compatibility libraries installed on a 64-bit linux system anymore

* we updated the included GnuPG-binaries from 1.4.16 to 1.4.18 for fixing some security issues

New alpha release 0.4

This release additionally contains binaries for MacOS. But since we had to rewrite the whole core, this release needs a lot of testing. So, if you want to be sure, better get the stable release. If you want to have a look what is planned for the release when it is finished have a look on our TODO-List.

VaultPad v1.2

webfork on 2 Nov 2016
  • 988KB (uncompressed)
  • Released on 7 Dec 2014
  • Suggested by kitsaros

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.

Blowfish Advanced CS v2.57

Checker on 15 Mar 2014
  • 679KB (uncompressed)
  • Released on
  • Suggested by Andrew Lee

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.

Loaded but still private...

Mixture on 2011-12-29 16:39

Cosimo, shouldn't you admit that the actual file limit is only 64Mb in the lowest Noise/Data ratio (300%). The actual text limit is a limited 46k in the same Noise/Data ratio. That mean's a 64Mb file automatically grows 4 times bigger and there's nothing you can you about it! A 46k text file grows over 5 fatter! What good it that?

Mixture on 2012-07-28 03:41

I tested version 2.00 of this bizarre software. It doesn't look any better. It certainly hasn't performed any better. Still the same old bad limitations. I would not recommend this software.
