The Essential Features and Cost of building a Messaging App like Signal!

WhatsApp used to be the most popular messaging app, but not anymore, ever since its revised privacy policy was declared in January 2021. This policy asked users to share their personal information to Facebook. Needless to say, this declaration has adversely affected WhatsApp’s sky-high popularity as one of the most secure and encrypted messaging options. And, the Signal messaging app, which was earlier unnoticed by messaging app users, started to be adopted as the ideal replacement for safe messaging.

Signal has gained an undisputed reputation of keeping users’ chats and calls truly encrypted and private. Even high-profile users like Elon Musk, Brian Action, and Edward Snowden have endorsed Signal’s uncontested privacy quotient, because of the level of secrecy and security it offers.

Investing in a messaging app like Signal is a brilliant idea and many of you must have already started the app ideation process as well! So, this post explores the unique selling points of Signal, the necessary features to include while building a Signal-like app, and provides an approximate idea on signal app development cost.

Signal App: An overview

Signal is a cross-platform messaging application that follows the approach of app models like Red Phone and Text Secure. It has bagged the reputation of being the most encrypted and secure application available in the market. Signal, being open-sourced; its source code is available on GitHub and can be accessed easily.

Using Signal chat, users can avail of one-to-one messaging as well as group chatting in the most secure manner possible. Users can share images, voice notes, files, and videos and make video/audio calls without having to worry about the risks of account hacks or data breaches. The reason is that Signal adheres to highly encrypted messaging protocols like Double Ratchet Algorithm, Extended Triple Diffie-Hellman, HMAC-SHA256, Curve25519, and AES-256, to rule out any chances of MITM (man-in-the-middle) hacking attempts. Moreover, all calls and messages that take place over the app are end-to-end encrypted, such that even Signal cannot access users’ data. Furthermore, the app doesn’t allow users to take a screenshot.

This revolutionary app has been created by the Signal Technology Foundation and the Signal messenger LLC.

Signal’s Unique Functioning Protocol to ensure Security

Here’s how an encrypted messaging application works!

When the app is installed on a smartphone, a permanent key pair gets created. This key pair consists of a “public” and a “private” key that are meant to encrypt and decrypt messages. The process of encrypting and decrypting works like this – the “public” key is sent to the messaging server for identifying users and the private key stays within the users’ smartphones. And, if this private key is compromised, the users’ messages become vulnerable to security threats like decryption and misuse.

The Signal messenger uses a more secured protocol. It generates several temporary key pairs besides their permanent keys. This function empowers the app to change the key after each message. When a user sends a message to another user via Signal, it integrates the temporary and permanent pairs of public as well as private keys for both the users to create a shared secret key. This secret key encrypts and decrypts the message. And, as the private keys of users must be accessed for generating the secret key, the secret key stays only on the devices of the users involved in the messaging act.

Moreover, Signal adheres to the protocol of continuously replenishing keys for each user, and this function allows the app to acquire new shared keys after each message. Also, features like disappearing messages, turning off the lock screen notification option, blurred photos, and encrypted calls; tighten the app’s security further.

Essential Features to include in your Signal-like Chat/Messaging App

Real-time Messaging and Object Sharing

Real-time messaging is a core prerequisite; using this feature users enjoy real-time interaction from any part of the globe. The multiple object-sharing features enable users to share media, documents, contacts, and even their present location with other users either privately or via group messaging.

In-app Audio/Video Calling

The in-app audio/video calling feature is a must-have in messaging apps as it allows individuals across the globe to connect with each other from one single platform.

Privately encrypted chats

This functionality needs to be integrated into your messaging application as it restricts server access to metadata including chats, icons, titles, and membership icons.

Inviting Friends

Users should be able to invite their friends/acquaintances. So, your app should integrate “invite friends” feature that will request users to provide access to their contact details for inviting friends or acquaintances. This way, the users will be able to send the invitation link directly to the individuals they wish to add.

Disappearing Messages & Lockable Chats

The disappearing messages and lockable chat features provide users the flexibility to maintain the privacy of their personal life. Users can set a timer of their choice – 5 seconds, or even one week. After the end of the timeline chosen by the user, the messages will disappear automatically, without being stored in any cloud server.

“Delete for Everyone” feature

Signal allows one to delete messages (for everyone) unlike WhatsApp. Hence, users have the option to delete messages sent by mistake or simply if they wish to do so. So, integrating such a feature will attract users.

Voice over Internet Protocol

VoIP or the Voice over Internet Protocol feature is crucial as it offers a stable internet connection for ensuring an enriching communication experience, even during times of slower internet connectivity.

Support for Proxy Version

The proxy feature enables users to use the app seamlessly regardless of their location, even on instances when the app is blocked in some country. But, how? In Signal messaging, the proxy settings allow the user to make the necessary modifications for accessing the app since the data traffic remains opaque to the person who’s operating the proxy feature.

All You Need To Know About MICC Power Cables and Electrical Wiring

The world of electrical cables is as massive as this universe, with every new variety emerging superior to its predecessor. Although, there are many kinds of power cables available in the market, only a few are well known among the masses. One such lesser known variety is the Mineral Insulated Copper Clad cables, better known as MICC cables. A variety of electrical cables commonly used in power and control circuits of pivotal equipments, MICC cables are constructed with copper conductors which is enveloped with a copper sheath. Also known as Pyro cables and MI cables, these cables are insulated by powdered inorganic magnesium oxide which provides them resistance against high temperatures.

MICC cables are extensively used in environments which are exposed to higher temperature and pressure. Due to its mineral insulation, these cables provide excellent fire resistance which enables them to be used as heating cables for industrial and domestic applications. While the commonly used variety of these cables have 7 conductors in them, the ones which cater to larger applications and equipments may use 19 individual conductors for greater resistance. Due to its effective insulated arrangement, these cables are used in nuclear reactors, fire alarm systems, tunnels, ovens, factories, industrial furnaces, emergency power and lightning systems, hospital operating systems, temperature measurement devices, transport hubs, residential buildings, and in public buildings like cinema theaters and hotels.

MICC cables last longer as compared to plastic insulated cables. The durability of MICC cables can be attributed to its sturdy construction. The robust sheath and the powdered mineral insulation of the cables act as the protective gear of the conductors, preventing them from getting in contact with exterior elements. The functioning of these power cables is not hampered even when exposed to harsh environments for a longer period of time. Though the cable is made of extra-strong materials, its flexible competence is not compromised. The cables can be wound or bent as per the requirements without affecting its functioning. While renovating old mansions and heritage buildings, MICC cables are often the first choice of engineers as they blend easily with the stone work used.

Although MICC cables can handle high pressure, they are not suitable for applications which are subject to vibrations. Using the cables in equipments that vibrate or contract damages the exterior of the cables and its core; thus, affecting the performance of the cables and leading to failure in the operation. Moreover, these cables are manufactured with ratings up to 1000 volts only. This means MICC power cables cannot transmit electricity beyond 1000 volts. While these cables do not get corroded easily, a hole in the copper sheath or contact with ammonia-bearing compounds can easily accelerate moisture absorption, ultimately leading to corrosion and circuit failure. MICC cables have its own set of advantages and disadvantages. Hence, its always vital to analyze them before using them for various applications.
