There is an issue importing a trusted CA(Certificate Authority) certificate in to Oracle Wallet using OWM (Oracle Wallet Manager), ssl2ossl, or orapki command line utilities. The errors seen as follows:

Some trusted certificate could not be installed.


Couldn't generate valid wallet, error = 28750!

Investigation of this issue reveals the following points:


1. This is seen on all OWM versions from the following Oracle products:

2. OWM from Oracle Database 11g is able to successfully import this certificate.

3. orapki displays certificate successfully, however it fails while importing the certificate into wallet.

4. openssl is able to view the certificate.

5. mkwallet fails to display the certificate as in following example:

$ $ORACLE_HOME/bin/mkwallet -q ./AC_Certisign_G3_64.cer
