Method Detail

addToSNIServerNameListback to summary
pack-priv static List<SNIServerName> addToSNIServerNameList(List<SNIServerName> serverNames, String hostname)

Puts hostname into the serverNames list.

If the serverNames does not look like a legal FQDN, it will not be put into the returned list.

Note that the returned list does not allow duplicated name type.

Returns:List<SNIServerName>

a list of SNIServerName

Return the value of the boolean System property propName.

rawToSNIHostNameback to summary
private static SNIHostName rawToSNIHostName(String hostname)

Converts string hostname to SNIHostName.

Note that to check whether a hostname is a valid domain name, we cannot use the hostname resolved from name services. For virtual hosting, multiple hostnames may be bound to the same IP address, so the hostname resolved from name services is not always reliable.

Parameters
hostname:String

the raw hostname

Returns:SNIHostName

an instance of SNIHostName, or null if the hostname does not look like a FQDN

pack-priv static void reverseBytes(byte[] arr)
swapback to summary
private static void swap(byte[] arr, int i, int j)
toByteArrayback to summary
pack-priv static byte[] toByteArray(BigInteger bi)

Utility method to convert a BigInteger to a byte array in unsigned format as needed in the handshake messages. BigInteger uses 2's complement format, i.e. it prepends an extra zero if the MSB is set. We remove that.
