True- Both load tempKey and verify commands were successful.
False- Verification failure, Communication failure or IC command execution failure.
Random Number Generator
.random(long max)
This function returns a positive random Long between 0 and max.
Max can be up to the larges positive value of a long: 2147483647
Input: max
Long. (1-2147483647)
Output: Long 32 bits (4 bytes)
.random(long min, long max)
This function returns a random Long between min and max.
Min and max can be positive or negative numbers.
Input: min
Long. (-2147483647 to +2147483647)
Input: max
Long. (-2147483647 to +2147483647)
Output: Long 32 bits (4 bytes)
.getRandomByte(boolean debug)
This function returns a positive random byte.
Output: Byte
.getRandomInt(boolean debug)
This function returns a positive random integer.
Output: Unassigned 16-bit integer
.getRandomLong(boolean debug)
This function returns a Long.
Output: Long 32 bits (4 bytes)r
.updateRandom32Bytes(boolean debug)
This function gets a complete random number from the IC (all 32 bytes).
It stores it in a global public variable array called .random32Bytes
If you wish to access this global variable and use as a 256 bit random number,
then you will need to access this array and combine it's elements as you wish.
Output: Boolean
True- Random command execution successful.
False- Communication failure or IC command execution failure.
Example 1: Configuration
