Stored procedures
Returns a random number that can be used with the cryptographic technologies.
Example
// Retrieve an integer included between 0 and 2 147 483 647
ResRandom = RandomCryptoInteger()
// Retrieve an integer included between 0 and 34
ResRandom = RandomCryptoInteger(34)
// Retrieve an integer included between 7 and 21
ResRandom = RandomCryptoInteger(7, 21)
Syntax

Calculating a random number Hide the details

<Result> = RandomCryptoInteger()
<Result>: Integer
  • Random integer (included between 0 and 2 147 483 647),
  • -1 if an error occurred.

Calculating a random number with an upper bound Hide the details

<Result> = RandomCryptoInteger(<Upper Bound>)
<Result>: Integer
  • Random integer (included between 0 and the upper bound, inclusive),
  • -1 if an error occurred.
<Upper Bound>: Integer
Upper bound of returned number (included between 1 and 2 147 483 647).

Calculating a random number with a lower bound and an upper bound Hide the details

<Result> = RandomCryptoInteger(<Lower Bound> , <Upper Bound>)
<Result>: Integer
  • Random integer (included between the lower and upper bounds, inclusive),
  • -1 if an error occurred.
<Lower Bound>: Integer
Lower bound of returned number (included between 0 and 2 147 483 647)
<Upper Bound>: Integer
Upper bound of returned number (included between 1 and 2 147 483 647)
Remarks
  • The first call to the function can be quite long (about one second) because initializing the random mechanism is very complex.
  • InitRandom has no effect on the result of RandomCryptoInteger.
