Cryptography studies secure communication techniques that only allow the sender and the receiver to view the message by using a secret key.

Cryptography applications involve digital signatures or authentication, electronic or digital money, SIM card authentication, encrypting devices, sensitive emails, protecting confidential data, securing websites, WhatsApp encryption, etc.

In the coming years, encryption will go mainstream, if it has not already, and blockchains will be used more prominently for data storage, in which case hacking the system is close to impossible due to its decentralized nature.

The future of cryptography revolves around how well the new algorithms stand against the quantum computers because these computers will break all public-key cryptographic schemes used today.

Researchers are working on new quantum-resistant encryption methodologies apart from the existing code-based, lattice-based, hash-based, and multivariate systems.

According to the Bureau of Labor Statistics, the domain is expected to grow by 30% by 2028, making this an opportune time for people who like to solve puzzles.
