VSUsbLogon

VSUsbLogon allows to login Windows in a secure way via USB device, replacing the password based Windows login. You don’t need to remember and type your Windows password (but your system is still password protected). Users can be automatically logged into Windows as they insert the USB flash drive into the USB port. VSUsbLogon allows you to use PIN code to login Windows when USB device has been connected.

VSUsbLogon supports USB HDD, USB flash drives and other USB devices like iPod, iPhone, Samsung Galaxy ....

All user data are encrypted via AES 256 algorithm. And all user data are encrypted with using unique encryption key that is dependent from the unique user settings.

To configure logon procedure (after VSUsbLogon installation) please run the "VSUsbLogon" application (VSUsbLogonMgr.exe), connect your USB device to PC, select USB device, press "Assign" button on the window of "VSUsbLogon" application and fill the fields on the "Assign USB To User" window.

VSUsbLogon

You can assign an action (lock workstation, log off, hibernate, turn on standby mode, shutdown or restart the computer) to be performed after inserting/ejecting the USB device.
At successful creation of association between USB device and user the application window should look like:

VSUsbLogon

How user can log to Windows with USB device? VSUsbLogon adds USB login icon to the Windows logon screen when the configured device has been connected.

In case the PIN code was defined you will be automatically logged into Windows only when you insert this device into the USB port and enter valid value of PIN code. PIN code: you can type '0' to '8' digits.

VSUsbLogon

If "Auto Logon" option was selected you can be automatically logged to Windows when you insert the device into the USB port, it is not necessary to type your password and PIN code

VSEncryptor

VSEncryptor is an easy to use file and text encryption program. You can encrypt any file or text you choose. To access the file (or text) again, you would need access to the password that was used while encrypting.

VSEncryptor is a serious solution, but at the same time is easy to use and does not require any technical background – just select any file (or type text) and choose ‘Encrypt’ – or simply drag the file to the proper editor box.

VSEncryptor supports a variety of encryption algorithms, including AES-128, AES-192, AES-256, RC2, RC4, DES, Triple DES, Blowfish, Twofish, Serpent, Camellia, Skipjack, CAST-256, MARS, RC5, RC6, IDEA, SEED, SHACAL-2, XTEA, GOST.

VSEncryptor provides a command-line interface. Use
        VSEncryptor.exe <input file>
        VSEncryptor.exe /ifile <input file> [/ofile <output file>]
to open <input file> file. You can define name of destination file (<output file>) via "/ofile".

VSEncryptor is compatible with Windows 8/Windows 7/Vista/2008 Server/XP/2003 Server/2000 32- and 64-bit. VSEncryptor 32-bit requires approximately 3.7MB of free disk space, 64-bit edition - 6.5MB.

VSFileEncrypC

VSFileEncrypC is a command-line tool that allows you to encrypt/decrypt files.

The list of supported algorithms: AES-128, AES-192, AES-256, RC2, RC4, DES, Triple DES, Blowfish, Twofish, Serpent, Camellia, Skipjack, CAST-256, MARS, RC5, RC6, IDEA, SEED, SHACAL-2, XTEA, GOST.

All files encrypted by VSFileEncryptC can be decrypted by VSEncryptor. All files encrypted by VSEncryptor can be decrypted by VSFileEncryptC (only use same algorithm and password).

Command line to encrypt file:

VSFileEncryptC.exe /encrypt /ifile <input file> [/ofile <output file>] /alg <algorithm> [/password <password>] [/rewrite [/confirm]] [/locale <locale>] [/sound]

Command line to decrypt file:

VSFileEncryptC.exe /decrypt /ifile <input file> [/ofile <output file>] /alg <algorithm> [/password <password>] [/rewrite [/confirm]] [/locale <locale>] [/sound]

Command line to view the list of supported encryption algorithms:

VSFileEncryptC.exe /algs [/sound]

Where
    <input file> - input file to encrypt/decrypt;
    <output file> - output file;
    <password> - your password (empty password will be used if password has not been defined);
    <algorithm> - the name of the encryption algorithm (one of aes128, aes192, aes256, rc2, rc4, des, tripledes,
            blowfish, twofish, serpent, camellia, skipjack, cast256, mars, rc5, rc6, idea, seed, shacal2, xtea, gost);
    <locale> - Country/Region. For example: aus (or australia), aut (or austria), bel (belgium), bra (brazil), can (canada),
            china (chn, pr-china), cze (czech), dnk (denmark), fin (finland), fra (france), deu (germany), grc (greece),
            hkg (hong-kong), hun (hungary), iceland (isl), irl (ireland), ita (italy), jpn (japan), kor (korea),
            mex (mexico), nld (holland), nzl (new-zealand), nor (norway), pol (poland), prt (portugal), rus (russia),
            sgp (singapore), svk (slovak), esp (spain), swe (sweden), che (switzerland), twn (taiwan), tur (turkey),
            gbr (england), usa (america);

If output file not defined the program will try to create output file in the same folder where is the input file. In this case program adds ".enc" (for encrypted file and ".dec" for decrypted file) suffix into the name of the output file.

Use "/rewrite" to rewrite existing output file automatically.
Use "/confirm" to confirm the rewriting of the existing output file.
Use "/sound" to play a sound when the operation is complete.
Use "/?", "/help" or "/man" to show help.
You can use
    "/enc" instead of command "/encrypt",
    "/dec" - instead of "/decrypt",
    "/psw" - instead of "/password",
    "/algorithms" - instead of "/algs",
    "/a" or "/algorithm" - instead of "/alg",
    "/i" or "/inputfile" - instead of "/ifile",
    "/o" or "/outputfile" - instead of "/ofile".

Examples:

VSFileEncryptC.exe /algs
VSFileEncryptC.exe /encrypt /i "c:\docs\plans.doc" /o "d:\shared\plans.doc.enc" /alg blowfish
VSFileEncryptC.exe /encrypt /i "c:\docs\plans.doc" /o "d:\shared\plans.doc.enc" /alg blowfish /psw "321"
VSFileEncryptC.exe /encrypt /i "c:\docs\plans.doc" /o "d:\shared\plans.doc.enc" /alg blowfish /psw "321" /rewrite
VSFileEncryptC.exe /decrypt /i "d:\shared\plans.doc.enc" /o "c:\docs\plans.doc" /alg blowfish /psw "321"
VSFileEncryptC.exe /decrypt /i "d:\shared\plans.doc.enc" /o "c:\docs\plans.doc" /alg blowfish /psw "321" /locale grc

VSFileEncryptC is compatible with Windows 8/Windows 7/Vista/2008 Server/XP/2003 Server/2000 32- and 64-bit. VSFileEncryptC 32-bit requires approximately 1.6MB of free disk space, 64-bit edition - 2.7MB.
