Total entropy size = (Number of keys) x (Entropy size per key)
| Key Size (byte) | Entropy Size Per Key (byte) |
|---|---|
| 16 | 22,120 (21.6 KiB) |
| 32 (size of an AES-256 key) | 22,440 (21.9 KiB) |
| 64 | 23,080 (22.5 KiB) |
| 128 | 24,280 (23.7 KiB) |
| 256 | 26,680 (26.1 KiB) |
| 512 | 31,200 (30.5 KiB) |
| 1,024 (1 KiB) (1.0 KB) | 39,600 (38.7 KiB) |
| 2,048 (2 KiB) (2.0 KB) | 55,080 (53.8 KiB) |
| 4,096 (4 KiB) (4.1 KB) | 83,560 (81.6 KiB) |
| 32,768 (32 KiB) (32.8 KB) | 423,480 (413.6 KiB) |
To generate (or to sync) 100 of AES-256 keys, the entropy size will be
100 x 22,440 = 2,244,000 bytes = 2.1 MiB.
To generate (or to sync) 100 of 128-byte OTP keys, the entropy size will be
100 x 24,280 = 2,428,000 bytes = 2.3 MiB.
To generate (or to sync) 100 of AES-256 keys and 200 of 128-byte OTP keys, the entropy size will be
100 x 22,440 + 200 x 24,280 = 7,100,000 bytes = 6.8 MiB.
25 MiB entropy quota allows you to generate (or to sync)
25 * 1024 * 1024 / 22,440 = 1168 of AES-256 keys in total.
