Symmetric e-mail encryption tool
1 April 2005 | 0
PrivateFile 5.0 AES, available from Rits is a software encryption package that permits users to selectively encrypt and decrypt files using a variety of keys.
Previously a DES implementation, the new version uses Advanced Encryption Standard (AES) technology, the international standard for strong encryption based on the Rjindael algorithm. The software is aimed at businesses who are looking for a secure way of transmitting sensitive files and e-mails and runs on Windows 95, 98, 2000, Windows NT and Unix.
By incorporating AES into PrivateFile 5.0, Rits is now offering stronger encryption than most current standards for encryption, as AES encrypts data in blocks of 196 bits as opposed to the older DES standard of 64 bits. Longer key length means a larger number of possible encryption keys, which lowers the likelihood of someone decrypting data by guessing the key or by trying all possible keys.
PrivateFile 5.0 AES allows users to build self-decrypting executable files by simply specifying a file and a password or key. Running the executable will prompt for the key. Once the key is specified, the software will decrypt and save the file to a location chosen by the user.
A novel feature of PrivateFile is the self-decrypting program, which allows recipients to decode and read the message without having installed PrivateFile themselves. The recipient needs to have been sent the password or key to decrypt the transmitted file. This can be done by voice, text messaging or traditional mail.
AES is a symmetric encryption algorithm, which means that the same key both encrypts and decrypts the data. Evaluation copies lasting 30 days may be downloaded from www.private-file.com. Client version licences can be bought for €63.00 per person with volume discounts applying for more than ten people. The server version is priced at €760 per server installation.
