Does this skill support Bring Your Own Key (BYOK) patterns?

Yes, it provides implementation strategies for BYOK, allowing enterprise customers to provide and manage their own encryption keys for their specific tenant data.

What is cryptographic tenant isolation?

Cryptographic isolation is a security pattern where each tenant's data is encrypted with its own unique key, ensuring data remains unreadable to other tenants or unauthorized parties even if the database is compromised.

How does it handle key rotation?

It provides logic for generating new key versions, re-encrypting existing tenant data with the new key, and safely retiring old keys after a defined grace period.

Can this be integrated with Entity Framework Core?

Absolutely. The skill includes patterns for EF Core Value Converters that automatically handle encryption and decryption during data access, making the process transparent to the application logic.

Security & Testing

Implements advanced cryptographic isolation and secure key management for multi-tenant SaaS applications.

About

This skill provides expert guidance and implementation patterns for securing tenant data in SaaS environments through cryptographic isolation. It moves beyond basic logical isolation to implement sophisticated encryption-at-rest strategies using a robust key hierarchy (KEK/DEK). The skill includes practical implementation patterns for C# and .NET, featuring Azure Key Vault integration, automated key rotation, EF Core Value Converters for column-level security, and Bring Your Own Key (BYOK) workflows to meet enterprise compliance standards.

Key Features

Automated key rotation patterns for compliance and security maintenance
EF Core Value Converters for transparent column-level encryption
Multi-level data isolation architectures from logical to HSM-backed
Per-tenant encryption key (DEK) generation and management
5 GitHub stars
Azure Key Vault integration for secure key wrapping and unwrapping

Use Cases

Implementing 'Bring Your Own Key' (BYOK) features for enterprise clients
Building high-security SaaS platforms requiring strict data segregation
Automating cryptographic compliance and key rotation in multi-tenant databases
