The internal structure of keys is dictated by the need for cloning.
|
|
We store everything besides the key data itself in a 32-bit bitmask,
|
|
with the following structure (byte-aligned for simplicity, in order
|
|
from least to most significant):
|
|
|
|
Bits Usage
|
|
0 Extractable
|
|
1-7 [reserved]
|
|
8-15 KeyType
|
|
16-23 KeyUsage
|
|
24-31 [reserved]
|
|
|
|
In the order of a hex value for a uint32_t
|
|
|
|
3 2 1 0
|
|
1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0
|
|
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|
|
|~~~~~~~~~~~~~~~| Usage | Type |~~~~~~~~~~~~~|E|
|
|
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|
|
|
|
Thus, internally, a key has the following fields:
|
|
* uint32_t - flags for extractable, usage, type
|
|
* KeyAlgorithm - the algorithm (which must serialize/deserialize itself)
|
|
* The actual keys (which the CryptoKey must serialize)
