keytool

I am using Java keytool . I have exported a self-signed .pem certificate from my keystore. Is there a command to view the certificate details directly from the .pem file (not of the certificate in the keystore)? Drona Use the -printcert command like this: keytool -printcert -file certificate.pem StampyCode An alternative to using keytool , you can use the command openssl x509 -in certificate.pem -text This should work for any x509 .pem file provided you have openssl installed. 来源： https://stackoverflow.com/questions/9758238/how-to-view-the-contents-of-a-pem-certificate

Usually I fetch Android Package (APK) Certificate information using the below command : keytool -printcert -jarfile <APK> but recently I have noticed that MD5 column is missing from the output. I just get SHA1 and SHA256 as seen in output below : Getting Certification Info. --------------------- Owner: CN=XYZ Issuer: CN=XYZ Serial number: 4e98b743 Valid from: Wed Mar 13 16:46:46 IST 2019 until: Sun Mar 06 16:46:46 IST 2044 Certificate fingerprints: **SHA1**: A5:32:37:D5:5B:31:6B:B2:09:48:BA:B1:EA:08:8C:RE:CB:23:24:B6 **SHA256**: 65:89:43:AD:54:65:12:D5:B3:C5:CA:BA:F4:7E:79:02:B5:AE:C9:C5:E8:06

I am doing the jetty SSL configuration . I have created CSR using keytool which has added a private key to the keystore, Received the certificate based on the CSR, converted the certificate to DER format and imported the certificate into the keystore as trustcacerts The signed certificate has the root/intermediate certificates in the certificate path I also installed the root and intermediate certificate in the IE under the trusted root certificate after converting it into DER format. while using https , the browser shows certificate error and considers the certificate as self signed

I wonder if I am able to make a connection using curl like the following command, curl --cacert some.pem https://someurl.com/resource How do I convert this to httpclient code? I understands I need to convert the pem file and create a new keystore, etc. But all these openssl, keytool commands, keystore, truststore confuses me, I don't know which one to use and in which order. Bruno You need to create a keystore (which you'll use as a trust store) from the PEM file. This can be done as follows. keytool -import -file cacert.pem -alias myca -keystore truststore.jks You then need to use this
