Module encryption

Nikon encryption key management and ProcessNikonEncrypted foundation

Trust ExifTool: This code translates ExifTool’s Nikon encryption system verbatim.

ExifTool Reference: lib/Image/ExifTool/Nikon.pm ProcessNikonEncrypted function

Nikon’s encryption system uses multiple keys derived from camera metadata:

• Serial number (tag 0x001d) as primary encryption key
• Shutter count (tag 0x00a7) as secondary encryption key
• Model-specific decryption algorithms

Phase 1 Implementation: Key management and detection only Phase 2 Implementation: Encrypted section detection and cataloging Phase 3+ Implementation: Actual decryption algorithms (future milestone)
