Mathematical dimensions or how old is mother earth?
From time to time you read about very huge numbers in connection with cryptography. The dimensions of these numbers are gigantic. This list may give you an idea of these dimensions. You can compare popular key lengths with some numbers from nature.
| 2 to power of | Approximates to |
| 30 | Age of planet earth (in years) |
| 33 | Probability of being killed by a lightning (per day) |
| 61 | Lifetime of universe in seconds |
| 128 | Amount of possible keys used by Steganos |
| 170 | Amount of atoms on our planet |
| 223 | Amount of atoms in our galaxy |
| 2048 | Amount of possible Steganos-InKA keys |
The probability of being killed by a lightning is 2││ to 1, this is about 8.5 billion to 1.
Note: 128 bit provide are maximum security. For most private and commercial applications 60 bit key length is sufficient.
