## replace_synology_ssl_certs.sh
#!/bin/bash
#
# *** For DSM v7.x ***
#
# How to use this script:
#  1. Get your 3 PEM files ready to copy over from your local machine/update server (privkey.pem, fullchain.pem, cert.pem)
#     and put into a directory (this will be $CERT_DIRECTORY).
#     Personally, I use this script (https://gist.github.com/catchdave/3f6f412bbf0f0cec32469fb0c9747295) to automate steps 1 & 4.
#  2. Ensure you have a user setup on synology that has ssh access (and ssh access is setup).
#     This user will need to be able to sudo as root (i.e. add this line to sudoers, <USER> is the user you create):
#       <USER> ALL=(ALL) NOPASSWD: /var/services/homes/<USER>/replace_certs.sh
#  3. Copy this script to Synology: sudo scp replace_synology_ssl_certs.sh $USER@$SYNOLOGY_SERVER:~/
#  4. Call this script as follows:
#     sudo bash -c scp ${CERT_DIRECTORY}/{privkey,fullchain,cert}.pem $USER@$SYNOLOGY_SERVER:/tmp/ \
#     && ssh $USER@$SYNOLOGY_SERVER 'sudo ./replace_synology_ssl_certs.sh'
