Package: seenoevil
🙈 See No EvilClient side encrypted pastebin.It has been designed to be short and simple to read.Data is encrypted at the client. It only hasone JS dependency.Web and CLI clients are provided. They both share the same JS library for encrypting and decrypting.How it worksThe fragment identifier of the URL (#)is never sent to the server:Interpretation of the fragment identifier is performed solely by the agent that dereferences a URI; the fragment identifier is not passed to other systems during the process of retrieval. This means that some intermediaries in Web architecture (such as proxies) have no interaction with fragment identifiers and that redirection (in HTTP [RFC2616], for example) does not account for fragments.Each time a user sends data to See No Evil:A random key is generated at the client.The client encrypts the data with this key.The client sends the encrypted data to the server.The server stores the encrypted data.The server returns a safe URL pointing to the encrypted data.The client appends the random key it generated to the received URL as a fragment identifier and shows it to the user.Then the user can share this URL with someone else:The server responds with the encrypted data.The client extracts the key from the URL fragment identifier, decrypts the data, and shows it to the user.FeaturesEvery secret has an expiration date. A temporal task deletes the expired ones every ten minutes.Every secret has a maximum number of reads. After all the reads are consumed, the secret is deleted.The server has a REST API. A command line interface is provided.Demohttps://seenoevil.herokuapp.comUsageServer$ pipenv install
