PROBLEM STATEMENT: Our research seeks to understand the current usability situation of files and encryption software. Particularly we focus in Gnupg4win encryption software and Thunderbird application and the integration of them. The study was to find current problems in the following areas: 1)Downloading the software and setting it up. 2)Creating a key pair. 3)Getting public keys published,. 4) Encrypting/decrypting files. 5) Encrypting/decrypting s. We conducted user testing to find out whether people can easily use those software applications to encrypt files and s. RESULTS: SIGNIFICANCE: In this research, we wanted to know whether average people know the concept of encryption and why the majority of people don't encrypt their s. We tried to determine if the reason is that people don't really need to use encryption or if it is because encryption is too complex. Previous researches claimed that the main reason behind this is the complexity of the encryption software. RESEARCH QUESTIONS:  Do majority of average people understand the concept of cryptography?  Why cryptography is not used with s?  Are free cryptography products really too complicated for average people to use?  Can we make these products more usable by providing good instructions? The Usability of File and Encryption Student: Tamam Alayed, Faculty Sponsor: Prof. Charles Frank, Computer Science METHODS: In this research we used standard user testing techniques. We conduct a survey to discover the reasons behind why people don’t use encryption tools. We also did some user testing to know whether people can benefit from using a simple good instruction for encryption tools. CONCLUSION:  Cryptographically protected s has been considered to be difficult to use for vast majority of people, not only because of the difficulty of the encryption tools itself but also due to people don’t see any need to use them for their s because it’s just not necessary for the kind of s that they send.  55.24% of 148 persons in our survey answered “Yes” when they answered the question “Would you use an encryption tool to encrypt your s if you have known simple instructions to do that”.  25.45% of 148 persons reported that they don’t send encrypted s because they don’t know how to use the encryption tools either due to the idea of the difficulty of encryption tools or the lack of good instruction to use it.

Is it really important to encrypt our s when we already know that almost all providers uses SSL? The usability of file encryption, focusing in TrueCrypt, open-source disk encryption tool.
