' SSLv2 Nyob zoo ' yog ib qho pseudo-txoj cai uas tso cai rau Java los pib sib tuav tes nrog ib qho SSLv2' nyob zoo lus'. Qhov no tsis ua rau kev siv SSLv2 raws tu qauv, uas tsis txhawb Java txhua. Thiab los ntawm JSSE Reference Guide: Kev siv JSSE hauv J2SDK 1.4 thiab tom qab ntawd siv SSL 3.0 thiab TLS 1.0.

Ua li no, SSLv2 puas ruaj ntseg?

Kev thauj mus los tsis ruaj ntseg Kev ruaj ntseg Raws tu qauv txhawb ( SSLv2 ) Netsparker kuaj pom tias tsis muaj kev thauj mus los kev ruaj ntseg raws tu qauv ( SSLv2 ) tau txais kev txhawb nqa los ntawm koj lub vev xaib server. SSLv2 muaj ob peb flaws. Piv txwv li, koj ruaj ntseg kev khiav tsheb tuaj yeem pom thaum koj tau tsim nws dhau SSLv2.

Ib yam li ntawd, kuv yuav ua li cas pab SSLv3 hauv Java? Yog tias Java 8 hloov tshiab 31 tau raug teeb tsa, SSLv3 yuav tsum tau qhib manually:

  1. Mus rau Java installation nplaub tshev.
  2. Qhib {JRE_HOME}libsecurityjava. kev ruaj ntseg -file hauv cov ntawv nyeem.
  3. Mus rau kab kawg.
  4. Tshem tawm lossis tawm tswv yim tawm cov kab hauv qab no "jdk. tls. disabledAlgorithms=SSLv3".
  5. Rov pib qhov kev pabcuam MC lossis rov pib lub server.

Ib yam li ntawd, SSLv3 puas ruaj ntseg?

SSL version 3.0 tsis yog lawm ruaj ntseg . SSLv3 yog ib tug qub version ntawm lub kev ruaj ntseg system uas underlies ruaj ntseg Kev lag luam hauv web thiab hu ua " ruaj ntseg Sockets Layer" (SSL) los yog "Transport Layer Kev ruaj ntseg ” (TWS).

SSL / TLS yog siv hauv txhua qhov browser thoob ntiaj teb los muab https (http ruaj ntseg) ua haujlwm.
