类 Authenticator

java.lang.Object

org.openeuler.sun.security.ssl.Authenticator

直接已知子类:

Authenticator.SSLAuthenticator

abstract class Authenticator
extends Object

This class represents an SSL/TLS message authentication token, which encapsulates a sequence number and ensures that attempts to delete or reorder messages can be detected.

方法详细资料

valueOf

static Authenticator valueOf(ProtocolVersion protocolVersion)

Constructs the message authentication token for the specified SSL/TLS protocol.

valueOf

static <T extends Authenticator & Authenticator.MAC> T valueOf(ProtocolVersion protocolVersion,
                                                               CipherSuite.MacAlg macAlg,
                                                               SecretKey key)
                                                        throws NoSuchAlgorithmException,
                                                               InvalidKeyException

抛出:

NoSuchAlgorithmException

InvalidKeyException

nullTlsMac

static Authenticator nullTlsMac()

seqNumOverflow

abstract boolean seqNumOverflow()

Checks whether the sequence number is close to wrap. Sequence numbers are of type uint64 and may not exceed 2^64-1. Sequence numbers do not wrap. When the sequence number is near to wrap, we need to close the connection immediately.

返回:

true if the sequence number is close to wrap

seqNumIsHuge

abstract boolean seqNumIsHuge()

Checks whether the sequence number close to renew. Sequence numbers are of type uint64 and may not exceed 2^64-1. Sequence numbers do not wrap. If a TLS implementation would need to wrap a sequence number, it must renegotiate instead.

返回:

true if the sequence number is huge enough to renew

sequenceNumber

final byte[] sequenceNumber()

Gets the current sequence number.

返回:

the byte array of the current sequence number

increaseSequenceNumber

final void increaseSequenceNumber()

Increase the sequence number.

acquireAuthenticationBytes

byte[] acquireAuthenticationBytes(byte type,
                                  int length,
                                  byte[] sequence)

Acquires the current message authentication information with the specified record type and fragment length, and then increases the sequence number if using implicit sequence number.

参数:

type - the record type

length - the fragment of the record

sequence - the explicit sequence number of the record

返回:

the byte array of the current message authentication information

toLong

static final long toLong(byte[] recordEnS)
