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.
