When importing a certificate into a keystore file, you may receive the following error message:

"keytool error: java.security.cert.CertificateParsingException: invalid DER-encoded certificate data"


This error occurs when the certificate file containing invalid formatting characters or carriage returns.


To resolve the problem, perform the following steps:

1. Open the certificate in an ASCII text editor (Use Notepad or another plain text editor)

2. Ensure that the first line starts with -----BEGIN CERTIFICATE----- and ends with -----END CERTIFICATE-----

3. Carefully ensure there is no space or blank within your certificate file, by selecting the entire text and looking for blank spaces.

4. If a blank space or line exists, delete it, and install your certificate file again.
