Jmeter not loading the client certificate

Jmeter creating the keystore but not loading it successfully. Both in .p12 or .jks format

I have tried adding the jssecacerts jre/lib/security Converted .cer to .p12 , .jks and .keystore Created a keystore config in jmeter and added start and end index 0 - as I have only one certificate Created csv file with the alias name

When loading .jks and .keystore

ERROR - jmeter.util.SSLManager: Problem loading keystore: No key(s) found java.io.IOException: No key(s) found at org.apache.jmeter.util.keystore.JmeterKeyStore.load(JmeterKeyStore.java:152) at org.apache.jmeter.util.SSLManager.getKeyStore(SSLManager.java:133)

Using .p12

jmeter.util.SSLManager: JmeterKeyStore Location: C:\tests\OrgInfo\ks\certnew.p12 type pkcs12 2019/05/21 14:58:10 INFO - jmeter.util.SSLManager: KeyStore created OK 2019/05/21 14:58:10 ERROR - jmeter.util.SSLManager: Problem loading keystore: DerInputStream.getLength(): lengthTag=109, too big. java.io.IOException: DerInputStream.getLength(): lengthTag=109, too big. at sun.security.util.DerInputStream.getLength(Unknown Source) at sun.security.util.DerValue.init(Unknown Source)

I have tried uploading the certificates from system.properties as well as Options->ssl manager nothing works.
