我不知道這是否爲時已晚,但BountyCastle添加到你的項目,你只需將它添加到您要在在做加密類:
static {
Security.addProvider(new org.spongycastle.jce.provider.BouncyCastleProvider());
}
下面是一個例子:
import java.security.SecureRandom;
import java.security.Security;
public class SHA1PRNG {
//here i swapped out the bountycastle provider and used the spongycatle
static {
Security.addProvider(new org.spongycastle.jce.provider.BouncyCastleProvider());
}
public static void main(String[] args) throws Exception {
SecureRandom rng = SecureRandom.getInstance("SHA1PRNG");
rng.setSeed(711);
int numberToGenerate = 999;
byte randNumbers[] = new byte[numberToGenerate];
rng.nextBytes(randNumbers);
for(int j=0; j<numberToGenerate; j++) {
System.out.print(randNumbers[j] + " ");
}
}
}
