Deprecated - do not instantiate this directly, as you won't get the
good one (Fortuna).

void |
feedEntropy(java.lang.String source,
byte[] data,
int offset,
int len) |
Feed the entropy pools with data[offset:offset+len]
|
void |
feedEntropy(java.lang.String source,
long data,
int bitoffset,
int bits) |
Feed the entropy pools with the bits in the data
|
static RandomSource |
getInstance() |
Singleton for whatever PRNG i2p uses.

boolean |
initSeed(byte[] buf) |
May block up to 10 seconds
|
void |
loadSeed() |
May block up to 10 seconds
|
void |
nextBytes(byte[] buf,
int offset,
int length) |
Not part of java.util.SecureRandom, but added since Fortuna supports it.
|
int |
nextInt(int n) |
According to the java docs (http://java.sun.com/j2se/1.4.1/docs/api/java/util/Random.html#nextInt(int))
nextInt(n) should return a number between 0 and n (including 0 and excluding n).
|
long |
nextLong(long n) |
Like the modified nextInt, nextLong(n) returns a random number from 0 through n,
including 0, excluding n.
