On the computer stored files can arrive on various way into the wrong hands. Only the encryption of the data can prevent this. The abylon CRYPTDRIVE offers a simple procedure to create encrypted drives, the so-called container. By the using of the encryption algorithm Blowfish (448 bits) or AES (256 bits) the files and programs are secure for unauthorized access. The access over the File Explorer is only possible, if the encrypted drive is mounted. The encryption and decryption of files works automatically and in the background. As secret to open the CRYPTDRIVE you can enter a password over the keyboard or alternatively you use a Smartcard, CD or a USB-Stick. In the company environment also the access authorizations can be administered over certificates. Numerous certificate Smartcards or USB-Token are supported.

Banking, you email account and the windows logon are only some examples for using a password. Can you keep all passwords and access data in your mind? The abylon KEYSAFE is a simply password manager to manage all your secret data. You need only one password or alternatively an USB-Stick, CD, chip card or certificate as "keys". The stored data can simply pull with the mouse into the appropriate fields of the Browsers or dialogue (Drag&Drop). With abylon KEYGENERATOR the software also offer a random password generator.

The abylon SHAREDDRIVE (encrypted file clipboard) is shown in the MS File Explorer as an independent drive. The complete integration into the Explorer environment simplify the using of the software. When storing files in the SHAREDDRIVE the encrypting (Blowfish - 448 bits / AES - 256 bits) works automatically in the background, without additional operation by the user. The file-based structure allow the simultaneous access of several users, on crashes limits the data loss to a minimum and reduces the data transfer volume in case of a backup. The encrypted files can be stored on the local computer, on a network computer or a ftp server. Security is increased by masking of the file names. Over the network or internet the transfer of the data is always encrypted. The encryptions occurs only on the client. As secret (key) can be used a password, a Smartcard, a USB-Storage medium or a CD/DVD to open the SHAREDDRIVE. In companies for the access authorization also the use of X.509 certificates (HYBRID-System, PKCS, RSA) are supported.

Active Fraud Shield is a trustworthy and sophisticated internet stream filter that detects, displays and blocks almost all fraud attempts. It is designed for the PayPal online payment service in order to protect PayPal accounts against phishing and fraud. Active Fraud Shield is a proxy program, scanning all internet traffic for detection of PayPal phishing or fraud. The utility uses special rules and a special detection engine. It both blocks dangerous sites and/or informs the user about them. The utility features a number of customization options allowing the user to create new everyday rules for detecting potential PayPal phishing, add own blacklists, set the frequency of update. The program has a special Blacklist that works with the lists of sites, found and named by Google and Phistank. Besides that, Active Fraud Shield allows the user to create own Blacklists or Whitelists by adding new URL, IP or other sources.

The program gets all information directly from PayPal. Active Fraud Shield features exclusive heuristics and proven parallel services, such as Phishtank. Compared to usual phishing and fraud detectors built into IE, FireFox or Opera, Active Fraud Shield is the No.1 PayPal account protector, as it offers filled blacklists. Different phishing and fraud sites arise every day, so there is a need for constant search for such sites and adding them to the blacklist. Active Fraud Shield uses a special Heuritsic and Site Analyze System that carefully traces new sites and adds them automatically. The program also has a special, permanently updated IP List that checks the sites against the official PayPal IP lists. Active Fraud Shield is a pleasure to work with thanks to its transparency and simplicity. Active Fraud Shield requires Windows Vista/XP/2003/2000/Me/98, 64MB RAM, 6MB hard drive space, Internet connection recommended, supports Internet Explorer/Netscape/Mozilla/Firefox/Opera/AOL.

Typically you encrypt files because you don't want others to see them, but sometimes you want to send someone an encrypted file. Most if not all encryption programs allow you to do so--they vary, however, in terms of how difficult the process is. AEP2007 PRO most noteworthy feature may be its flexibility: Not only can you encrypt files for your own protection but you can easily create "self-decrypting" versions of your files that others can run without needing AEP2007 PRO or any other software. The program includes a file shredder that wipes the contents of your original files. It also integrates nicely with Windows Explorer, allowing you to use Explorer's context menus and avoid having another window clutter your screen. It also uses military grade encryption for protecting your private files. Program includes 17(!) undustrial encryption algorithms: DESX, BLOWFISH, RIJNDAEL(AES), CAST, 3-DES, RC2, DIAMOND2, TEA, SAFER, 3-WAY, GOST, SHARK, SQUARE, SKIPJACK, TWOFISH, MARS, SERPENT.
The latest version has support for RSA algorithm and Public-Private Key cryptography. One key is kept secret and is referred to as the private key while the other is made available to others and is called the public key since anyone can access this key. These keys are large mathematically-related numbers derived from algorithms that form a unique pair. Either key may be used to encrypt a message, but only the other corresponding key is used to decrypt the message. AEP Command Line Tool has support for all RSA alg. features.
AEP2007 PRO supports skins technology and has 10 nice additional skins.
Complete support for Command Line Interface. Support for USB Flash Drives to store passwords in protected form.

The MD5 Com Component creates an RFC1321 compliant MD5 string from a string of text or file content, The MD5 algorithm takes as input a string of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input string. It is conjectured that it is computationally infeasible to produce two messages having the same message digest, or to produce any message having a given prespecified target message digest. The MD5 algorithm is intended for digital signature applications, where a large file must be "compressed" in a secure manner before being encrypted with a private (secret) key under a public-key cryptosystem such as RSA. In essence, MD5 is a way to verify data integrity, and is much more reliable than checksum and many other commonly used methods.
