InstallCert.java

Java program written by Andreas Sterbenz, and posted on a blog in Oct, 2006:

https://blogs.oracle.com/gc/entry/unable_to_find_valid_certification

Link to Java program in Andreas' blog no longer works, but the source was linked in another blog:

Usage:

Need to compile, first:

javac InstallCert.java

Note: since java 11, you can run it directly without compiling it first:

java --source 11 InstallCert.java 

# Access server, and retrieve certificate (accept default certificate 1)

java InstallCert [--proxy=proxyHost:proxyPort] [:port] [passphrase]

# Extract certificate from created jssecacerts keystore

keytool -exportcert -alias [host]-1 -keystore jssecacerts -storepass changeit -file [host].cer

# Import certificate into system keystore

keytool -importcert -alias [host] -keystore [path to system keystore] -storepass changeit -file [host].cer

# Example:

java InstallCert woot.com:443

    Loading KeyStore /usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/security/cacerts...

    Opening connection to woot.com:443...

    Starting SSL handshake...

    javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

       md5     e8 a5 88 1b d5 67 bb fc 88 cc b1 c5 2b ac c4 7d 

    Enter certificate to add to trusted keystore or 'q' to quit: [1]
