Returns a secure random boolean
Fills the given byte array with random bytes.
Returns a secure random double value. The value is uniformly distributed between 0.0 and 1.0
Returns a secure random float value. The value is uniformly distributed between 0.0 and 1.0
Returns a secure random double value. The value is Gaussian ("normally") distributed with mean 0.0 and standard deviation 1.0
Returns a secure random int
Returns a secure random int, between 0 (inclusive) and the specified bound (exclusive).
Returns a secure random long
Returns a Base64 url encoded String of random data with the given length. The length parameter refers to the length of the String before the encoding step.
Get or create a secure non blocking random number generator using the current vert.x context. If there is no current context (i.e.: not running on the eventloop) then a IllegalStateException is thrown.
Note, if a context isn't allowed to be used, for example, exceptions are thrown on getting and putting data, the VertxContextPRNG falls back to instantiate a new instance of the PRNG per call.
Get or create a secure non blocking random number generator using the current vert.x instance. Since the context might be different this method will attempt to use the current context first if available and then fall back to create a new instance of the PRNG.
Note, if a context isn't allowed to be used, for example, exceptions are thrown on getting and putting data, the VertxContextPRNG falls back to instantiate a new instance of the PRNG per call.
Generated using TypeDoc
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.
