DLOCK2
By Michael Paul Johnson
DLOCK2 is a simple command line file encryption/decryption utility program that uses the free Diamond 2 Encryption Algorithm. Full source code and documentation of the algorithm and the master''s thesis it is based on are included. It compiles with Gnu C++ and other compilers, so it can be adapted to many operating systems. Version 2.01 is the same as the original DLOCK2, except recompiled for the Win32 command line (for long filename support) and author contact information has been updated. The encryption key may be a passphrase on the command line or it may be contained in a file. You may use the included encryption/decryption source code in your own products at no charge. This software is free, however you may send the author donations to express appreciation if you like.
fSekrit
By DonationCoder
fSekrit is a small application for keeping encrypted notes. The real advantage of fSekrit is that notes are truly self-contained; the editor program and your note are merged together into a tiny self-contained program file, removing the need to install a special application to view your data. This makes fSekrit ideal for keeping encrypted notes on, for example, USB flash drives. Another advantage of using fSekrit is that your un-encrypted data is never stored on your harddisk. With a traditional encryption utility you would have to decrypt your file to disk, view or edit it, and then re-encrypt it, and unless you use secure file wiping tools, it would be a trivial matter for someone to to retrieve your un-encrypted data, even though you have deleted it. This can''t be done with fSekrit, though, since it never stores your un-encrypted data on disk. fSekrit uses very strong encryption (256-bit AES/Rijndael in CBC mode) to ensure that your data is never at risk. Self contained fSekrit notefiles are tiny! Only 40k plus the size of your text.

Absolute Password Protector
By LastBit Software
Absolute Password Protector is a strong steganography utility that securely encrypts files. The program makes your secret photos, videos or messages invisible for unwanted people. With the use of Absolute Password Protector, you can also hide encrypted files so that no one would know it''s an encrypted file. Encrypted files can be safely transferred via e-mail. Absolute Password Protector adds "invisible" noise to digital photographic images. This noise will contain your sensitive data in an encrypted form. There are a lot of password protection utilities on the market today that promise a secure storage for your files. Unfortunately, simple password protection techniques do not guarantee safety and passwords are easily recovered. LastBit Software is a company providing password recovery solutions since 1997. The company has a great experience in this field and did the best to make the encryption utility as strong as possible. Absolute Password Protector uses the CleverLock (TM) technology that dramatically increases the time and efforts needed to decrypt even a short password. So, maximum possible brute-force attack speed is about 100 passwords per second (for example, search speed for Zip archives is up to tens of millions of passwords per second). There is no need to start the program each time you wish to encrypt or decrypt a file. Absolute Password Protector integrates into the Windows shell and can be invoked by a right click on a file, while in Windows Explorer. Encrypt files with a single mouse click!
