海外TECH	DEV Community	Build End-to-End Encryption in 51 lines of Rust	https://dev.to/mrinal/build-end-to-end-encryption-in-51-lines-of-rust-340p	Build End to End Encryption in lines of Rust ockam network ockam End to end encryption and mutual authentication for distributed applications Ockam is a rust library that makes it simple for distributed applications to guarantee end to end integrity authenticity and confidentiality of data In this post we ll create two small Rust programs called Alice and Bob Alice and Bob will send each other messages over the network via a cloud service They will mutually authenticate each other and will have a cryptographic guarantee that en route messages were not tampered or forged The intermediary cloud service and attackers on the network will not be able to see or change the contents of en route messages In later examples we ll also see how we can have this end to end protection even when the communication path between Alice and Bob is more complex with multiple transport connections a variety of transport protocols and many intermediaries Show me the code Remove implicit trust in porous network boundariesModern distributed applications operate in highly dynamic environments Infrastructure automation microservices in multiple clouds or data centers a mobile workforce the Internet of Things and Edge computing mean that machines and applications are continuously leaving and entering network boundaries Application architects have learnt that they must lower the amount of trust they place in network boundaries and infrastructure The vulnerability surface of our application cannot include all code that may be running within the same porous network boundary That surface is too big too dynamic and usually outside the control of an application developer Applications must instead take control of the security and reliability of their own data To do this all messages that are received over the network must prove who sent them and show that they weren t tampered with or forged Lower trust in intermediariesAnother aspect of modern applications that can take away Alice s and Bob s ability to rely on the integrity and authenticity of incoming messages are intermediary services such as the cloud service in our example below Data within distributed applications are rarely exchanged over a single point to point transport connection Application messages routinely flow over complex multi hop multi protocol routes ーacross data centers through queues and caches via gateways and brokers ーbefore reaching their end destination Typically when information or commands are exchanged through an intermediary service the intermediary is able to READ the messages that are being exchanged UPDATE en route messages CREATE messages that were never sent and DELETE never deliver messages that were actually sent Alice and Bob are entirely dependent on the security of such intermediaries If the defenses of an intermediary are compromised our application is also compromised Transport layer security protocols are unable to protect application messages because their protection is constrained by the length and duration of the underlying transport connection If there is an intermediary between Alice and Bob the transport connection between Alice and the intermediary is completely different from the transport connection between Bob and the intermediary This is why the intermediary has full CRUD permissions on the messages in motion In environments like Microservices Internet of Things and Edge Computing there are usually many such intermediaries Our application s vulnerability surface quickly grows and becomes unmanageable Mutually Authenticated End to End Encrypted Secure Channels with OckamOckam crate makes it simple for applications to create any number of lightweight mutually authenticated end to end encrypted secure channels These channels use cryptography to guarantee end to end integrity authenticity and confidentiality of messages An application can use Ockam Secure Channels to enforce least privileged access to commands data configuration machine learning models and software updates that are flowing as messages between its distributed parts Intermediary services and compromised software that may be running within the same network boundary no longer have implicit CRUD permissions on our application s messages Instead we have granular control over access permissions tampering or forgery of data in motion is immediately detected With end to end secure channels we can make the vulnerability surface of our application strikingly small Rust ExampleLet s build end to end protected communication between Alice and Bob through a cloud service We ll create two small Rust programs called Alice and Bob We want Bob to create a secure channel listener and ask Alice to initiate a secure handshake authenticated key exchange with this listener We ll imagine that Bob and Alice are running on two separate computers and this handshake must happen over the Internet We ll also imagine that Bob is running within a private network and cannot open a public port exposed to the Internet Instead Bob registers a forwarding address on an Ockam Node running as a cloud service in Ockam Hub This node is at TCP address node ockam network and offers two general purpose Ockam services routing and forwarding SetupIf you don t have it please install the latest version of Rust curl proto https tlsv sSf shNext create a new cargo project to get started cargo new lib hello ockam amp amp cd hello

vault Vault create amp ctx Create an Entity to represent Bob let mut bob Entity create amp ctx amp vault Create a secure channel listener for Bob that will wait for requests to initiate an Authenticated Key Exchange bob create secure channel listener listener TrustEveryonePolicy The computer that is running this program is likely within a private network and not accessible over the internet To allow Alice and others to initiate an end to end secure channel with this program we connect with node ockam network as a TCP client and ask the forwarding service on that node to create a forwarder for us All messages that arrive at that forwarding address will be sent to this program using the TCP connection we created as a client let node in hub TCP node ockam network let forwarder RemoteForwarder create amp ctx node in hub listener await println n ✓ RemoteForwarder was created on the node at node ockam network println Forwarding address for Bob is println forwarder remote

this program will run until you stop it with Ctrl C Ok AliceCreate a file at examples alice rs and copy the below code snippet to it examples alice rsuse ockam route Context Entity Result

program cargo run example bobThe Bob program creates a Secure Channel Listener to accept requests to begin an Authenticated Key Exchange It also connects over TCP to the cloud node at node ockam network and creates a Forwarder on that cloud node All messages that arrive at that forwarding address will be forwarded to Bob using the TCP connection that Bob created as a client Bob also starts an Echoer worker that prints any message it receives and echoes it back on its return route The Bob program will print a hex value which is the forwarding address for Bob on the cloud node copy it In a separate terminal window in the same directory path run the Alice program cargo run example aliceIt will stop to ask for Bob s forwarding address that was printed in step Give it that address This will tell Alice that the route to reach Bob is TCP node ockam network forwarding address When Alice sends a message along this route the Ockam routing layer will look at the first address in the route and hand the message to the TCP transport The TCP transport will connect with the cloud node over TCP and hand the message to it The routing layer on the cloud node will then take the message to the forwarding address for Bob The forwarder at that address will send the message to Bob over the TCP connection Bob had earlier created with the cloud node Replies from Bob take the same path back and the entire secure channel handshake is completed is this way End to end Secure Channel is established Send messages to Bob and get their echoes back Once the secure channel is established the Alice program will stop and ask you to enter a message for Bob Any message that you enter is delivered to Bob using the secure channel via the cloud node The echoer on Bob will echo the messages back on the same path and Alice will print it ConclusionCongratulations on creating your first end to end encrypted application We discussed that in order to have a small and manageable vulnerability surface distributed applications must use mutually authenticated end to end encrypted channels Implementing an end to end secure channel protocol from scratch is complex error prone and will take more time than application teams can typically dedicate to this problem In the above example we created a mutually authenticated end to end encrypted channel in lines of code excluding comments Ockam combines proven cryptographic building blocks into a set of reusable protocols for distributed applications to communicate security and privately The above example only scratched the surface of what is possible with the tools that our included in the ockam Rust crate To learn more please see our use case guide on End to End Encryption through Kafka and our Step by Step Deep Dive into the various
