How to print certificate Information from Keystore folder

Hi,

I am having one .jks file in keystore and IS/Config/certs folder. I need to change it to .cer format and wanted to print the certificate information. How can i do it?
cert.docx (41.6 KB)

Did you try using keytool?

Yes did you tried that and also if you want to change the extenstion from .der to .cer you can do via extention rename did that not work for you?

Hi,

be careful when just renaming from .der to .cer as this might break the certificate handling due to invalid certificate format.

.cer usually indicates a plain text X.509 certficate whereas .der is a binary encoded variant of the same.

This can be verified by opening the certificate with an editor.

Plain text X.509 is formated like this:


-----BEGIN CERTIFICATE-----
MII.....
....
....
-----END CERTIFICATE-----

The binary encoded certificate is not readable by humans.
