Found incosistencies in instalation user var/files namings, to have it consistend and easy to understand and considering everyone is more familiar with INSTALL_USER
Changed $pivpnUser to INSTALL_USER
Changed pivpnUSR to INSTALL_USER
Removed PiVPN Secure Notes from PiVPN ADD introduced with PR #794
- Notes not being pushed to BW Vault
- OVPN files not going to ovpns dir
- Needs investigation
Code assumes that the specified user directory is under /home. This code parses the /etc/passwd file in order to determine what that user's proper home directory is.
Added new step to create an .ovpn12 file that can be stored on iOS keychain
This step is more secure method and does not require the end-user to keep entering passwords, or storing the client private cert where it can be easily tampered based on documentation located:
https://openvpn.net/faq/how-do-i-use-a-client-certificate-and-private-key-from-the-ios-keychain/
Someone can improve upon this by adding a parameter (possibly -i|--iOS) and then generating the original .ovpn file to not contain the client private certificate.
As @fyellin There is some chatter on other groups that some
OpenVPN implementations cannot handle client keys that are
encrypted with RSA.
If the client key is encrypted, we might re-encrypting the
current client key using 3DES.
This commit will convert user client key to 3DES in command
`pivpn -a`
P/S: All credits to @fyellin. Many thanks to him.
