Password Tech v3.1.0 Updated

billon on 22 Jun 2020
  • 7MB (uncompressed)
  • Released on 14 Jun 2020
  • Suggested by I am Baas

Password Tech (formerly PWGen) provides a variety of security tools including a strong random password and data file generator, master password tool, and a text encryption tool.

  • Random number generator - the program can create lists of random characters or pass-phrases from word lists and uses mouse/keyboard activity to gather more entropy. The program includes lots of features to make these passwords easy and conform to any security standard.

  • Master password - lets you create strong passwords using two words, usually a single password with it's destination, creating strong passwords for every site ("email" is unique from "network"). It's an easy way to avoid writing down your passwords but always having them available.

  • Text encryption - draws from any application that supports a text copy/paste to encode (using the cliboard).
For both encryption and password generation, the program uses an open, standard algorithm (AES 256).

Why was Gaijin.at Password Generator removed from the database? I have just tested it and it seems to be really portable.

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.

SteganoG v1.30

billon on 6 Apr 2017

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.

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).

gpg4usb v0.3.3-2

webfork on 23 May 2018
  • 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 commercial 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.

Drag'n'Crypt ULTRA v2.3.9

webfork on 28 Feb 2017
  • 652KB (uncompressed)
  • Released on 20 Jan 2015
  • Suggested by Fluffy

Drag'n'Crypt ULTRA is a small file encryption tool that uses a handy "drop box" interface to make encryption and decryption fast and easy. Uses the Twofish encryption algorithm

Note:

  • File size is limited. Maximum file size depends on 1/2 free memory (for example: with a RAM of 512 MB RAM you can encrypt a 256 MB file). The author recommends TrueCrypt for larger files.
  • The website is in German, but the program is in English.
  • Starting from version 2.2.0, Drag'n'Crypt ULTRA is no longer backwards-compatible with data encrypted using Blowfish or TEA.

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.
