Encrypt-then-MAC vs macOS FileVault

Developers should use Encrypt-then-MAC when building systems that require secure data transmission or storage, such as in web APIs, messaging apps, or file encryption tools, to defend against tampering and eavesdropping meets developers should use filevault when working on macos systems that handle confidential data, such as source code, api keys, or user information, to comply with security best practices and regulations like gdpr or hipaa. Here's our take.

Encrypt-then-MAC

Nice Pick

Developers should use Encrypt-then-MAC when building systems that require secure data transmission or storage, such as in web APIs, messaging apps, or file encryption tools, to defend against tampering and eavesdropping

Pros

• It is particularly crucial in scenarios where data integrity is as important as confidentiality, like in financial transactions or sensitive communications, as it ensures that any modification of encrypted data is detected before processing
• Related to: cryptography, message-authentication-code

Cons

• Specific tradeoffs depend on your use case

macOS FileVault

Developers should use FileVault when working on macOS systems that handle confidential data, such as source code, API keys, or user information, to comply with security best practices and regulations like GDPR or HIPAA

Pros

• It is particularly useful for remote work, device sharing, or in corporate environments where data breaches pose a significant risk, as it provides full-disk encryption without requiring third-party tools
• Related to: disk-encryption, macos-security

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Encrypt-then-MAC is a concept while macOS FileVault is a tool. We picked Encrypt-then-MAC based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Encrypt-then-MAC wins

Based on overall popularity. Encrypt-then-MAC is more widely used, but macOS FileVault excels in its own space.
