What do you do if you're an information security professional looking to learn about cryptography?

There are many online courses that can explain Cryptography and they range from basic to advanced. Udemy, Coursera have some really good courses. Also Let's Defend Platform has one for beginners as well (FREE) which will be beneficial for someone starting in the field.

certifique-se de pesquisar as op??es disponíveis e ler as avalia??es dos alunos para garantir que o curso seja de alta qualidade e atenda às suas necessidades de aprendizado. Lembre-se também de que a prática e a aplica??o dos conhecimentos adquiridos s?o essenciais para aprofundar sua compreens?o da criptografia.

If you're hungry to delve deeper into cryptography as an infosec pro, books and research papers are your go-to. One of the books I found helpful during my studies is Serious Cryptography: A Practical Introduction to Modern Encryption. Don't shy away from academic papers and wikis to learn more and staying updated on the latest breakthroughs.

tart by understanding the fundamental concepts of cryptography, including encryption algorithms, cryptographic protocols, key management, and cryptographic attacks. For this platforms like coursera, cybarary can be good starting point.

If you're an information security professional seeking to delve into cryptography, consider exploring online courses such as "Cryptography I" on Coursera by Stanford University or "Applied Cryptography" on Udemy by Jean-Philippe Aumasson. These courses offer comprehensive insights into cryptographic principles, algorithms, and their practical applications in securing data and communications.

Despite the adage of "never roll your own cryptography" it is important to have the foundations of understanding the mathematics involved and the implementations. Getting practice by working out the mathematics on paper or in a calculator is key. Then from there, implementing these algorithms in the language of your choice. You probably won't want to use these implementations in production, but it's incredibly valuable to implement algorithms yourself. Once you've done this, another key skill is to work to find vulnerabilities in your implementations, and try to create practical breaks for them. This will help you understand where implementations go wrong, and will be an invaluable skill along your path of understanding cryptography.

Identify workshops, seminars, and conferences related to cryptography and information security. These events often feature talks and workshops by leading researchers and practitioners, providing valuable insights into the latest advancements in the field. Engage in online cryptography challenges and competitions, such as those hosted on platforms like Cryptopals or OverTheWire.

I personally learn (not from reading) but from doing. Get your hands dirty and start playing around with crypto for data in transit and data at rest (disk or file level).

Stay informed about the latest research papers, publications, and developments in cryptography by following reputable journals, blogs, and newsletters in the field. Keeping up-to-date with emerging trends and advancements is essential for staying relevant in cryptography. Cryptography is a rapidly evolving field, so make a commitment to continuous learning and self-improvement. Stay curious, explore new topics, and never stop expanding your knowledge and skills in cryptography.
