Key Wrapping

A cryptographic technique used to encrypt and protect cryptographic keys.

Understanding:


Key wrapping is a cryptographic method used to securely encrypt encryption keys to ensure they remain confidential.

Common Applications and Use Cases:


  • Secure Key Exchange – Protects keys during transmission.

  • Cloud Encryption – Used in AWS KMS, Google Cloud KMS, etc.

  • Digital Rights Management (DRM) – Secures cryptographic keys.

Best Practices and Security Considerations:


  • Use NIST-Approved Algorithms (AES-KW, RSA-OAEP) – Ensures strong encryption.

  • Limit Key Exposure – Reduces attack surface.

  • Rotate Wrapped Keys Regularly – Prevents long-term compromise.
