| # 1. Magic Number : Fix string « MSPD - 0x4D535044 » |
| # 2. Timestamp: Image creation timestamp. |
| # 3. CRC: 32 Bit CRC on full header. At the time of CRC calculation this field should be 0. |
| # 4. Image Hash Type: Hash Type 0/Sha-256/Rsa-Sha-256. |
| # I. Zero -- Initialized with all zero [size 32 bytes]. |
| # II. SHA-256 . SHA-256 hash on the image [size 32 bytes]. |
| # III. RSA-SHA-256 . RSA encrypted sha-256 hash on the image [size key size]. |
| # 5. Key Length: Length of Public Key 0/1K,2K. Zero means no key. |
| # 6. Image Length: Length of Current Image (excluding header). |
| # 7. Hash value: Hash result 256/1K/2K bits. |
| # 8. Public key (optional): Public key used for firmware authentication (Size 1K/2K/4K) |
