Rootconf Sessions

Secure Coding practices are one of the important aspect in security. Cryptography is another such domain which is often missed while taking care of security. In this session, the audience will learn about basic cryptography and the algorithms used. We will be discussing about some insecure practices and why they should not be used. Once, the audience is well aware of the basics, we will deep dive a bit more into it and learn about implementing good crypto practices in CI/CD pipeline and learning about some security practices in Devops.

Outline

Introduction to crypto and hashing algorithms
1.1 RSA
1.2 ECDSA
1.3 MD5
1.4 SHA-256
1.5 HMAC (SHA-256)
How not to leak your secrets
2.1 Weak private keys in asymmetric ciphers
2.2 Hash collisions (MD5 exmaple)
2.3 Small length and pulically known secrets for symmetric ciphers and HMAC
2.4 Case study Don’t Role your own crypto
2.5 OSINT (github and google dorks examples) leading to secret key information disclosures, good practices that you can implement in your CI/CD pipeline
Awesome data privacy with crypto tools and services
3.1 Tor Onion v3 services for DevOps
3.2 How not to be careless while deserializing data from your session tokens and auth headers (Ex: JWT, flask-session) for system related operations
3.3 AES-CBC with PKCS
