Caching private users private keys

[ysissoko78]

Hello,

need to know if it is secure to cache the requested private key (redis, or in memory store) to avoid making provider requests each time we need to send a transaction to the blockchain?

Thanks

Hi Youssouf,

Thanks for reaching out with your query!

Regarding your question about securely caching the requested private key, security is a crucial aspect to consider when caching private keys. Here are some points to consider:

1. In-Memory Storage:

   • Pros: Fast access, doesn’t persist after the application restarts.
   • Cons: Vulnerable to memory dumps and access by other processes. Always ensure your server is secure and access is restricted.

2. Redis:

   • Pros: Fast access and it can be configured for persistence.
   • Cons: If not properly secured and configured, it can be vulnerable to unauthorized access or attacks. Using encrypted databases might help.

3. General Security Considerations:

   • Use strong encryption for storing private keys.
   • Ensure proper access controls are in place.
   • Regularly rotate keys and review your security policies.
   • Make sure to use secure providers and only make requests from trusted environments.

However, caching private keys is generally not recommended if they can be fetched or generated on demand securely. The trade-offs between performance and security should be carefully evaluated based on your specific use case and requirements.
