When we try to launch the Admin tool we get the following error.
CacheEntry[https://milg1lxidash01.vcorp.ad.vrsn.com:8000/idash/AdminTool.jnlp]: updateAvailable=true,lastModified=Fri Feb 11 16:17:00 EST 2022,length=3427
#### Java Web Start Error:
#### Unsigned application requesting unrestricted access to system
Unsigned resource: https://milg1lxidash01.vcorp.ad.vrsn.com:8000/idash/encr.jar
Release : 12.1.02
The issue is that the upgrade package of JRE 1.8.0.351_b31 have disabled SHA-1 Signed JARs.
Please follow the steps below:
Modify the java.security file As Administrator edit "C:\Program Files (x86)\Java\jre1.8.0_351\lib\security\java.security" Search for and comment the following line: "jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024, \" find the lines:
jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024, \
DSA keySize < 1024, include jdk.disabled.namedCurves, \
SHA1 denyAfter 2019-01-01
You will need to comment out the "SHA1 denyAfter 2019-01-01" line, but also need to remove the ", \" on the preceding line. So should look like this:
jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024, \
DSA keySize < 1024, include jdk.disabled.namedCurves
# SHA1 denyAfter 2019-01-01
Save and re-launch jnlp.
