crypto.koans
A collection of koans for learning basics of practical cryptography using koans.
Target Audience: People working with libcurl, libopenssl and having to deal with PKI. You should have a reasonable understanding of shell scripts and code.
Requirements
openssl version(1.1.1a)curl --version(7.64.0)php --version(7.3.2)php -m |grep -e openssl -e curlcomposer --version(See https://getcomposer.org/download/) (1.8.4)docker --version(18.09.2-ce)libtasn(brew install libtasn1) (4.13)
Setup
Koans:
- OpenSSL Basics
- Generating Private Keys
- Understanding File Formats in Crypto
- Curl Basics
- CA Certificates and CSRs
See TODO.md for more details on planned Koans.
This tries to prevent high-level tools and abstractions to get a better appreciation of how things are under the hood. However, while writing real-world crypto code, please use higher level abstractions such as NaCl.
