FaxLauncher keeps your documents secure on the Internet by providing RSA encryption to ensure the files are both encrypted and authenticated to be originating from a particular user.
How RSA Encryption Works
FaxLauncher always sends faxes using RSA encryption.Our online registration, as included on the disk or in the download from our web site uses RSA encryption.
Our basic encryption scheme is to use the FaxSav Incorporated public key to encrypt the users password and a symmetric key that is generated for "this" session. We then send this information followed by the body of the document, e.g., the fax or the registration information, encrypted with the symmetric key and using the RC4 algorithm.
In other words, in the users system we generate:
SMTP/FTP Session:
The public key encryption is slow -- too slow to use for the body of the fax. It uses a 512 bit key and can only be decrypted using the "paired" private key that is held at FaxSav. When the AUTHENTICATION/SESSION INFO is received we decrypt it using our private key, authenticate the user, and extract the symmetric key that was generated at the user's workstation.
When we receive the body of the information we decrypt it on the fly using the symmetric key. The symmetric key is generated using "random" information extracted from the workstation environment. It is a 40 bit key.
Our product has been approved by the Department of State per their guidelines for export.
