Greetings! We’re excited to announce that we’ve unveiled a brand-new cryptography course on We’re convinced that this new experience is truly one of a kind. If you want to learn cryptography while writing real code in the Go programming language, you should check it out.

You can get started for free here.

Why learn cryptography? ๐Ÿ”—

Ever wondered how your data is kept safe online? This course will teach you about encryption, password security, ciphers, and more. After you master the fundamentals, you’ll learn how each cryptographic primitive is used in real-world applications.

If you’re interested in becoming a valuable back-end engineer, an understanding of cryptography will set you apart from other candidates that will fail to answer basic security questions.

Chapters ๐Ÿ”—

1. Symmetric Encryption ๐Ÿ”—

Learn the basics of cryptography: encrypting and decrypting a secret message with a key

2. Encoding ๐Ÿ”—

To be able to work with encrypted data, you need to understand how information is encoded in different formats

3. Brute Force ๐Ÿ”—

Learn about the most primitive, but most important kind of crypto attack

4. Caesar Cipher ๐Ÿ”—

Learn about the fundamentals of ciphers, starting with Julius Caesar’s famous cipher

5. XOR ๐Ÿ”—

Study the importance of the XOR operation in cryptography and how it can be used to create the perfect cipher

6. Stream Ciphers ๐Ÿ”—

Stream ciphers can be used to encrypt data as it flows through a system

7. Block Ciphers ๐Ÿ”—

Block ciphers are commonly used to encrypt large amounts of data at rest, like entire hard drives

8. DES ๐Ÿ”—

DES is an older block cipher that’s important to understand to appreciate modern block ciphers

9. AES ๐Ÿ”—

AES is a secure, modern block cipher that’s used in many production applications

10. Asymmetric Encryption ๐Ÿ”—

Asymmetric encryption is used in HTTPS, digital signatures, and anywhere two parties need to securely communicate

11. RSA ๐Ÿ”—

RSA is one of the most popular asymmetric encryption algorithms

12. Hash Functions ๐Ÿ”—

Hashing has many applications in cryptography, including password security and message integrity

13. Digital Signatures ๐Ÿ”—

Digital signatures are a way to prove that a message was sent by a particular party

14. KDFs ๐Ÿ”—

Key derivation functions are how we derive keys from passwords or other keys securely

What’s inside? ๐Ÿ”—

You’ll find text and image explanations of all the concepts, as well as video explanations of some of the more visually demanding lessons. You’ll be writing real code in Go in most of the exercises, and the platform will instantly check your code and provide feedback. You’ll only like the course if you enjoy an engaging hands-on experience.
