    • Courses

      • Cryptography I - The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems.
      • A Self-Study Course In Block-Cipher Cryptanalysis - This paper attempts to organize the existing literature of block-cipher cryptanalysis in a way that students can use to learn cryptanalytic techniques and ways to break algorithms, by Bruce Schneier.
      • Applied Cryptography - Cryptography is present in everyday life, from paying with a credit card to using the telephone. Learn all about making and breaking puzzles in computing.
      • Crypto Strikes Back! - This talk will cover crypto vulnerabilities in widely-deployed systems and how the smallest oversight resulted in catastrophe.
      • Cryptography - A practical oriented course in Cryptography by University of Maryland College Park.
      • Cryptography - Stanford University - This course explains the inner workings of cryptographic primitives and how to correctly use them. Students will learn how to reason about the security of cryptographic constructions and how to apply this knowledge to real-world applications.
      • Journey into cryptography - The course of cryptography by Khan Academy.
      • Theory and Practice of Cryptography - Introduction to Modern Cryptography, Using Cryptography in Practice and at Google, Proofs of Security and Security Definitions and A Special Topic in Cryptography.
      • Practical Aspects of Modern Cryptography - Practical Aspects of Modern Cryptography, Winter 2006 University of Washington CSE.
      • Cryptography 101: Building Blocks - This introductory course (Fall 2024) by Alfred Menezes covers the fundamental cryptographic primitives: symmetric-key encryption, hash functions, MACs, authenticated encryption, public-key encryption, signatures, key agreement, RSA, elliptic curve cryptography.

    • Algorithms

      • MD5 - Widely used hash function producing a 128-bit hash value. MD5 was initially designed to be used as a cryptographic hash function, but it has been found to suffer from extensive vulnerabilities. It can still be used as a checksum to verify data integrity, but only against unintentional corruption.
      • 3DES - Symmetric-key block cipher (or Triple Data Encryption Algorithm (TDEA or Triple DEA), which applies the Data Encryption Standard (DES) cipher algorithm three times to each data block.
      • AES - Symmetric-key block cipher algorithm and U.S. government standard for secure and classified data encryption and decryption (also known as Rijndael).
      • Blowfish - Symmetric-key block cipher, designed in 1993 by Bruce Schneier. Notable features of the design include key-dependent S-boxes and a highly complex key schedule.
      • DH - A method of exchanging cryptographic keys securely over a public channel. Unlike RSA, the Diffie-Hellman Key Exchange is not encryption, and is only a way for two parties to agree on a shared secret value. Since the keys generated are completely pseudo-random, DH key exchanges can provide forward secrecy (https://en.wikipedia.org/wiki/Forward_secrecy).
      • ECC - Public-key cryptosystems based on the algebraic structure of elliptic curves over finite fields.
      • RSA - One of the first practical public-key cryptosystems and is widely used for secure data transmission. In RSA, this asymmetry is based on the practical difficulty of factoring the product of two large prime numbers, the factoring problem.
      • SHA1 - Cryptographic hash function designed by the NSA. SHA-1 produces a 160-bit hash value known as a message digest. SHA-1 is no longer considered secure against well-funded opponents.
      • SHA2 - Set of hash functions designed by the NSA. SHA-256 and SHA-512 are novel hash functions computed with 32-bit and 64-bit words, respectively. They use different shift amounts and additive constants, but their structures are otherwise virtually identical, differing only in the number of rounds.
      • SHA3 - Cryptographic hash function that produces a fixed-size output, typically 224, 256, 384, or 512 bits, from variable-size input data. It is part of the SHA-3 family of cryptographic algorithms designed to resist attacks from quantum computers and offers security properties such as pre-image resistance, second pre-image resistance, and collision resistance.
