new VertxContextPRNG()
A secure non blocking random number generator isolated to the current context. The PRNG is bound to the vert.x
context and setup to close when the context shuts down.
When applicable, use of VertxContextPRNG rather than create new PRNG objects is helpful to keep the system entropy usage to the minimum avoiding potential blocking across the application.
The use of VertxContextPRNG is particularly appropriate when multiple handlers use random numbers.
Methods
nextInt() → {number}
Returns a secure random int
Returns:
random int.
- Type
- number
nextString(length) → {string}
Returns a Base64 mime encoded String of random data with the given length. The length parameter refers to the length
of the String before the encoding step.
Parameters:
Name | Type | Description |
---|---|---|
length |
number | the desired string length before Base64 encoding. |
Returns:
A base 64 encoded string.
