What is Cryptography?
Cryptography is the science of securing information by transforming readable data into an unreadable format, and vice versa, using algorithms such as AES (Advanced Encryption Standard). It protects confidentiality, integrity, and authenticity of messages, as seen in online banking, messaging apps, e‑commerce sites, social media platforms, or even smart home devices. It also prevents unwanted access wich is crucial.
Popular alternative names of Cryptography: Encryption Secret writing Ciphering Code‑making Secure communications Crypto
Major topics/subjects in Cryptography: - Symmetric-key cryptography: AES, DES, used in VPNs and SSL/TLS - Asymmetric-key cryptography: RSA, ECC, for email encryption and digital signatures - Cryptographic hash functions: SHA-2, SHA-3, used in blockchain and password storage - Digital signatures and certificates: PKI (Public Key Infrastructure) enabling trust on the web - Key exchange protocols: Diffie-Hellman for secure channel negotiation - Cryptanalysis: Breaking ciphers via statistical or algebraic attacks - Cryptographic protocols: SSL/TLS, SSH, IPsec
A brief history of most important events in Cryptography: Starting around 50 BCE with Julius Caesar’s substitution cipher, secret writing evolved slowly. In the 9th century, Al-Kindi introduced frequency analysis. The Vigenère cipher emerged in the 16th century and was hailed “le chiffre indéchiffrable” (the indecipherable cipher). During World War II, Enigma machines were cracked by Alan Turing’s team at Bletchley Park. The 1970s brought public-key cryptography: Diffie-Hellman key exchange and RSA revolutionized secure communication. In 2001, AES was selected to replace DES. Since then, cryptographic protocols like SSL/TLS have secured the web and online transactions. Recently, post-quantum cryptography research gained traction to protect against future quantum-computer attacks.
How can MEB help you with Cryptography?
If you want to learn Cryptography, our tutors at MEB offer one‑on‑one online help just for you. Whether you are a school, college, or university student, we can help you get top grades on assignments, lab reports, live tests, projects, essays, and big research papers. Our 24/7 instant Cryptography homework help is always ready.
We like to use WhatsApp chat to talk, but if you do not use it, you can email us at meb@myengineeringbuddy.com.
Although anyone can use our services, most of our students come from the USA, Canada, the UK, the Gulf, Europe, and Australia.
Students come to us when a subject is hard, assignments are too many, or questions and ideas take too long to figure out. They also ask for help if they have health or personal issues, part‑time jobs, missed classes, or just need more time to learn at their own pace.
If you are a parent and your ward is finding Cryptography hard, contact us today. Our tutors will help your ward do their best on exams and homework.
MEB also offers help in more than 1,000 other subjects. Our expert tutors make learning easier and help students succeed without stress.

What is so special about Cryptography?
Cryptography is special because it lets people keep information safe by turning it into secret code. Unlike other computer science subjects, it mixes math, logic, and computer skills to protect privacy. Its uniqueness lies in hiding data from hackers and making sure messages only reach the right people. It also creates trust online, which few subjects focus on so directly.
One advantage of cryptography is that it is key to online security and data protection, making it very useful in banking, messaging, and e‑commerce. It offers strong job opportunities and real‑world impact. However, cryptography can be hard to learn because of heavy math, proofs, and constant updates to face new threats. Compared to other topics, it needs deeper study and regular practice.
What are the career opportunities in Cryptography?
Students who focus on cryptography can go on to master’s or PhD programs in computer science or information security. Many universities now offer special tracks in quantum‐safe cryptography and blockchain security. Research labs at companies and schools also take in graduates for cutting‐edge studies.
Common job roles include cryptography engineer, security analyst, and research scientist. A cryptography engineer designs and tests secure algorithms, while security analysts monitor systems for weaknesses. Research scientists explore new encryption methods, often working with teams to build safer networks and software.
Learning cryptography prepares you to protect data and communications. Test prep helps you master key ideas like symmetric and asymmetric encryption, hashing, and digital signatures. Studying for certificates such as CISSP or CEH boosts job prospects and shows employers you’ve met industry standards.
Cryptography powers online banking, e‑commerce, and private messaging apps. It secures blockchains, IoT devices, and cloud services. Strong encryption keeps personal and business information safe from hackers and supports trust in digital systems.
How to learn Cryptography?
Start by building a solid math base in number theory and modular arithmetic. Follow a structured online course or textbook chapter by chapter. After each topic—like symmetric ciphers or public‑key cryptography—do hands‑on exercises or coding projects. Review your work, join study groups, and practice with real‑world problems, such as solving Cryptopals challenges.
Cryptography can feel tough at first because it uses abstract math and complex algorithms. With steady practice and good explanations, most students get comfortable. It’s a challenge, but not out of reach if you learn one concept at a time and keep applying it in small projects.
You can definitely start on your own using high‑quality videos, tutorials, and books. A tutor isn’t strictly required, but one-on‑one help can speed things up, clear up tricky proofs, and guide your projects. If you ever get stuck, an experienced tutor can save hours of confusion.
MEB offers 24/7 online 1:1 tutoring with expert Computer Science tutors who guide you through every concept, weekly progress checks, practice assignments, and clear feedback. We also help with cryptography homework and exam prep at affordable rates.
Most students need about 3–6 months of regular study (5–10 hours per week) to cover basic cryptography topics well. If you study more intensively, you could reach a solid level in 1–2 months. Depth and speed depend on your background in math and coding.
