Summary
Java runtime might throw a general import error in certain cases when using keytool command line utility.
Diagnosis
Running the following import command for an existing certificate file:
1
keytool -importcert -alias your.alias.here -keystore /PATH/TO/cacerts -file certificate.pemResults in one of the following errors:
1
keytool error: java.io.IOException: DerValue.getBigIntegerInternal, not expected 48OR
1
2
Warning: use -cacerts option to access cacerts keystore
keytool error: java.security. KeyStoreException: Unrecognized keystore format. please load it with a specified typeCause
Java's truststore is corrupt and keytool utility is not able to finish the import properly.
Solution
Extract a valid copy cacerts from the previously downloaded archive.
Import the certificate to the new truststore.
Replace the new cacerts with the corrupt old one.
Keytool utility used for import must be from the same JRE version the corrupt truststore comes from.
Make sure to update cacerts file ownership after overwriting the old one.
