我正在嘗試使用TLS調用服務器,只接受具有SNI支持的客戶端。無法在Java 7上啓用SNI
我正在使用Java 7的客戶:
$ java -version
java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)
應該是默認啓用,但是:
- 「它不工作」
- 我不能把它看成日誌中的擴展名
例如從我的日誌中:
Compression Methods: { 0 }
Extension elliptic_curves, curve names: {secp256r1, sect163k1, sect163r2, secp192r1, secp224r1, sect233k1, sect233r1, sect283k1, sect283r1, secp384r1, sect409k1, sect409r1, secp521r1, sect571k1, sect571r1, secp160k1, secp160r1, secp160r2, sect163r1, secp192k1, sect193r1, sect193r2, secp224k1, sect239k1, secp256k1}
Extension ec_point_formats, formats: [uncompressed]
Extension signature_algorithms, signature_algorithms: SHA512withECDSA, SHA512withRSA, SHA384withECDSA, SHA384withRSA, SHA256withECDSA, SHA256withRSA, SHA256withDSA, SHA224withECDSA, SHA224withRSA, SHA224withDSA, SHA1withECDSA, SHA1withRSA, SHA1withDSA
Extension renegotiation_info, renegotiated_connection: <empty>
***
雖然我希望找到
Extension server_name, server_name: [host_name: my.servername.com]
我嘗試添加該標誌-Djsse.enableSNIExtension=true
可以肯定的,但沒有成功。
我正在使用的Netty 4.0.37測試,並得到此異常:
io.netty.handler.codec.DecoderException: javax.net.ssl.SSLException: Received fatal alert: handshake_failure
at io.netty.handler.codec.ByteToMessageDecoder.callDecode(ByteToMessageDecoder.java:442)
at io.netty.handler.codec.ByteToMessageDecoder.channelRead(ByteToMessageDecoder.java:248)
什麼把戲上的Java 7 JVM啓用SNI?
