SecureRandomSpi
abstract class SecureRandomSpi : Serializable
| kotlin.Any | |
| ↳ | java.security.SecureRandomSpi |
This class defines the Service Provider Interface (SPI) for the SecureRandom class. All the abstract methods in this class must be implemented by each service provider who wishes to supply the implementation of a cryptographically strong pseudo-random number generator.

Public constructors
Protected methods
engineGenerateSeed
protected abstract fun engineGenerateSeed(numBytes: Int): ByteArray!
Returns the given number of seed bytes. This call may be used to seed other random number generators.
| Parameters | |
|---|---|
numBytes |
Int: the number of seed bytes to generate. |
| Return | |
|---|---|
ByteArray! |
the seed bytes. |
engineNextBytes
protected abstract fun engineNextBytes(bytes: ByteArray!): Unit
Generates a user-specified number of random bytes.
If a call to engineSetSeed had not occurred previously, the first call to this method forces this SecureRandom implementation to seed itself. This self-seeding will not occur if engineSetSeed was previously called.
| Parameters | |
|---|---|
bytes |
ByteArray!: the array to be filled in with random bytes. |
engineSetSeed
protected abstract fun engineSetSeed(seed: ByteArray!): Unit
Reseeds this random object. The given seed supplements, rather than replaces, the existing seed. Thus, repeated calls are guaranteed never to reduce randomness.
| Parameters | |
|---|---|
seed |
ByteArray!: the seed. |
