Method Detail

getTempArraySize

public static int getTempArraySize(int totalSize)

Get the size of a temporary buffer array to use in order to be cache efficient. totalSize indicates the total amount of data to be buffered. Used by the engineUpdate(ByteBuffer) methods.

getSecureRandom

public static java.security.SecureRandom getSecureRandom()

Get a SecureRandom instance. This method should be used by JDK internal code in favor of calling "new SecureRandom()". That needs to iterate through the provider table to find the default SecureRandom implementation, which is fairly inefficient.

getDefSecureRandom

public static java.security.SecureRandom getDefSecureRandom()

Get the default SecureRandom instance. This method is the optimized version of "new SecureRandom()" which re-uses the default SecureRandom impl if the provider table is the same.
