Error Importing SSL certificate : Not an X.509 Certificate

I am trying to Update the SSL certificate in accordance with this post
.

I am noob in certificates, so i followed this guide. But, when i enter

keytool -keystore mycacerts -storepass changeit -importcert -file "C:\Users\Noks\Desktop\cacerts.pem" -v


I get the error:

keytool error: java.lang.Exception: Input not an X.509 certificate
java.lang.Exception: Input not an X.509 certificate
at sun.security.tools.KeyTool.addTrustedCert(KeyTool.java:1913)
at sun.security.tools.KeyTool.doCommands(KeyTool.java:818)
at sun.security.tools.KeyTool.run(KeyTool.java:172)
at sun.security.tools.KeyTool.main(KeyTool.java:166)


How do i fix this?

Answer

Does your cacerts.pem file hold a single certificate? Since it is a PEM, have a look at it, it should start with

-----BEGIN CERTIFICATE-----

and end with

-----END CERTIFICATE-----

Finally, to check it is not corrupted, get hold of openssl and print its details using

openssl x509 -in cacerts.pem -text
