Cryptography Resources

---

Learn cryptography from interactive platforms and courses. 

• CryptoHack (https://cryptohack.org/): Solve puzzles and challenges to learn about cryptographic algorithms like RSA and AES.
• Coursera Courses  (https://www.coursera.org/courses?query=cryptography): Take courses in cryptography, applied cryptography, number theory, and more. 
• CryptoTool (https://www.cryptool.org): Learn cryptography through visual demonstrations and more. 

Dive into the technical details for theoretical or applied cryptography through in-depth books on cryptography by renowned cryptographers. *

• Real-World Cryptography by David Wong (https://www.amazon.com/Real-World-Cryptography-David-Wong/dp/1617296716)  A great first book and overview of applied cryptography covering modern schemes and protocols. It discusses post-quantum cryptography but does not provide overview of NIST selected schemes.
• Serious Cryptography: A Practical Introduction to Modern Encryption by Jean-Philippe Aumasson (https://a.co/d/5wCkgPQ): This book gives an overview of many topics in applied cryptography, including authenticated encryption, secure randomness, algorithms, and protocols. 
• Applied Cryptography: Protocols, Algorithms and Source Code in C by Bruce Schneier (https://a.co/d/hPOLQto): This book describes cryptography algorithms, gives practical implementation advice, and shows programmers how to build security into their software and systems. 

*Note: for the most up-to-date research its best to look on ePrint https://eprint.iacr.org/ or arXiv https://arxiv.org/,

Stay up to date on the latest cryptography trends and advancements with blogs and forums.

Learn about research, new algorithms, and standards in cryptography from cryptography-relevant organizations. 

• National Institutes of Standards and Technology (https://csrc.nist.gov): The National Institutes of Standards and Technology (NIST) has cryptography standards and algorithm specifications. In particular,  the NIST competition for new public-key cryptography that is secure against quantum computers (post-quantum cryptography) has details about the newest cryptographic algorithms and links each algorithm’s websites to learn more (https://csrc.nist.gov/Projects/post-quantum-cryptography).
• International Association for Cryptologic Research (https://www.iacr.org/): The International Association for Cryptologic Research (IACR) is a non-profit that furthers research in cryptology and related fields.

Attend conferences to learn about the newest research, implementations, or attacks in cryptography and network with other cryptography enthusiasts. 

• Crypto and Eurocrypt (https://iacr.org/conferences/): annual conferences on cryptography research
• RSA Conference ( https://www.rsaconference.com/):  an annual conference on cybersecurity that covers cryptography
• Black Hat and DEF CON ( https://www.blackhat.com/ and https://www.defcon.org/): security conferences that feature cryptography talks and workshops, particularly the DEF CON Crypto & Privacy Village (https://cryptovillage.org/)
