Convention: Byte array notation as it would appear in a hexeditor.

KDBX files, the keepass database files, are layout as follows:

1) Bytes 0-3: Primary identifier, common across all kdbx versions: 
  private static $sigByte1=[0x03,0xD9,0xA2,0x9A];

2) Bytes 4-7: Secondary identifier. Byte 4 can be used to identify the file version (0x67 is latest, 0x66 is the KeePass 2 pre-release format and 0x55 is KeePass 1)

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
