I have created a script to add trusted certificate chains to an orapki wallet from the Linux command line, and there is no web browser needed. It reads sites from a list and adds the certificate chains of those sites to an orapki (auto login) wallet.
Usage
Start the script with ./certs_to_wallet.sh <path to wallet> . This will prompt you for a NEW wallet (auto login) creation. The old wallet will be backed-up. In case of permission of password errors, the backup will be restored.
It reads a wallet_sites.lst file from the current directory or the wallet directory. The wallet directory takes preference, so you can have a list of sites per wallet. A site per line will be processed and the certificate chain will be added to the given wallet (the last line should be empty).
