Heresy: A Serverless Web Application to Store Compressed and Encrypted Document in the Form of URL

In this study, we propose Heresy, a web application to generate a document that solely exists in the form of a Uniform Resource Locator (URL) fragment. That document is compressed using Lempel-Ziv-Markov algorithm (LZMA) and encrypted using one of four symmetric-key cryptography algorithms: AES, Rabbit, RC4, and Triple DES. This allows a user to create a secured document using markdown markup language, and then share or save the generated URL. In order to view the document, a valid passphrase is needed. All operations are performed in the client machine (serverless). We analyzed the capability and performance of Heresy in several devices to find out the best cryptography algorithm to secure a document.
