Crypto 101 is a free, open-source introductory book on cryptography aimed at programmers, covering ciphers, hash functions, MACs, public-key encryption, and TLS. The repository contains the Sphinx source used to build the book in PDF, EPUB, and other formats.
Use cases
- learn cryptography from scratch
- understand how SSL/TLS works
- learn how common crypto flaws are exploited
- find a free cryptography book in PDF or EPUB
- teach an introductory cryptography course
- practice breaking weak cryptographic implementations
When to choose
- you want a free, beginner-friendly introduction to cryptography
- you learn best by exploiting real crypto flaws in code
- you need DRM-free material in multiple ebook formats
When to avoid
- you need a rigorous mathematical treatment of cryptography
- you want a maintained reference for the latest post-quantum schemes
- you need hands-on software rather than reading material
