Hi Team
I have IBM MQ 7.5 installed on SOlaris 10 machine.
SRVCONN channel has RC4_MD5_EXPORT cipher .
alter channel (xxxxx) +
chltype (svrconn) +
trptype (tcp) +
sslcauth (required) +
sslciph (RC4_MD5_EXPORT) +
sslpeer ('xxxx') +
mcauser
Java client has SSL_RSA_EXPORT_WITH_RC4_40_MD5.
sslciphersuite(SSL_RSA_EXPORT_WITH_RC4_40_MD5)
We have java 6 (ORACLE JRE ) running on SOlaris 10 machine.
Now we are planning to migrate to TLS 1.2 from SSL.
We tried below combinations :
TLS_RSA_WITH_AES_256_CBC_SHA256
TLS_RSA_WITH_AES_256_CBC_SHA
TLS_RSA_WITH_AES_128_CBC_SHA256
TLS_RSA_WITH_AES_128_CBC_SHA
But each time getting below error :
Caused by: com.ibm.mq.MQException: JMSCMQ0001: WebSphere MQ call failed with compcode '2' ('MQCC_FAILED') reason '2400' ('MQRC_UNSUPPORTED_CIPHER_SUITE').
at com.ibm.msg.client.wmq.common.internal.Reason.createException(Reason.java:209)
I am setting -Dcom.ibm.mq.cfg.useIBMCipherMappings=false \ when starting java client.
$JAVA_BIN -DJ=$JAMG_ID -DT="\"$TAG\"" \
-Djava.library.path=$java/lib \
-Djavax.net.ssl.trustStore=$java/cfg/key.jck \
-Djavax.net.ssl.trustStorePassword=xxx \
-Djavax.net.ssl.trustStoreType=jceks \
-Djavax.net.ssl.keyStore=$java/cfg/key.jck \
-Djavax.net.ssl.keyStorePassword=xxx \
-Djavax.net.ssl.keyStoreType=jceks \
-Dcom.ibm.mq.cfg.useIBMCipherMappings=false \
$xxx.xxx -f $FILE $DIROPT &
Would you please let us know what is wrong and which combination will wor k? |

Take a look in this IBM MQ KNOWLEDGE CENTRE ARTICLE, specifically Note 7.

You may also want to check the key size. If the key size is under 2048 you will not be able to run TLS.

Current java version is
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing)
I checked on google and found out that this particular version dosen't support TLS 1.2.
Is there any way by which i can upgrade to TLS 1.2 without changing JAVA 6. |

THIS is a good one, especially the second answer...
