If you used --daemon, you need to use --askpass to make passphrase-protected keys work, and you can not use --auth-nocache. $ tar xf com.whatsapp.tar apps/com.whatsapp/f/pw $ mv apps/com.whatsapp/f/pw . Jul 1 17:48:16 openvpn 70318 neither nor stdin stderr are a tty device and you have neither the controlling tty systemd nor - can not ask for 'Enter Private Key Password'. Remove Passphrase from Key openssl rsa -in certkey.key -out nopassphrase.key. Use the following command to extract the certificate from a PKCS#12 (.pfx) file and convert it into a PEM encoded certificate: openssl pkcs12 -in yourdomain.pfx -nokeys -clcerts -out yourdomain.crt $ openssl version OpenSSL 1.0.2n 7 Dec 2017 I feel like I must be missing something basic. ** NOTE: While the "openssl" command can accept a hex encoded 'key' and 'iv' ** it only does so on the command line, which is insecure. When a passphrase is required and none is provided, an exception should be raised instead. openssl pkcs12 -in yourdomain.pfx -nocerts -out yourdomain.key -nodes. As such I ** recommend that the output only be used with API access to the "OpenSSL" ** cryptography libraries. The following additional options may be used: -v --verbose Output additional information while running. Of course. Hello, when you establish a OpenVPN connection with a password protected ceritificate you have enter the passphrase each time when OpenVPN starts. I need to suppress the salt using the -nosalt option. If you’re looking to generate the /etc/shadow hash for a password for a Linux user (for instance: to use in a Puppet manifest), you can easily generate one at the command line. gpg-pre- set-passphrase will then read the passphrase from stdin. An example. See openssl_seal() for more information. openssl_open() opens (decrypts) sealed_data using the private key associated with the key identifier priv_key_id and the envelope key env_key, and fills open_data with the decrypted data. $ dd if=com.whatsapp.ab ibs=24 skip=1 | openssl zlib -d > com.whatsapp.tar Next, extract the password file and move it to the current working directory. ** ** FUTURE: Provide an optional argument to specify the Key+IV output size ** wanted. The password file is 69 bytes in size. If you used --daemon, you need to use to make --askpass passphrase-protected keys work, and you can not use --auth-nocache. This isn't nice if you want to connect at system startup without an user interaction. It's possible to store the password in a file and the OpenVPN Service/daemon reads the password from there. SOLVED by @mvy The problem was that a salt is randomly generated by default, but when you are specifying the key and iv for decryption, there should not be a salt. The envelope key is generated when the data are sealed and can only be used by one specific private key. I guess it should be the same size for everyone. in the Log. Contact us for help registering your account Hello! Now, upn starting the VPN Client I get openvpn[36396]: neither stdin nor stderr are a tty device and you have neither a controlling tty nor systemd - can't ask for 'Enter Private Key Password:'. --forget Flush the passphrase for the given cache ID from the cache. We noticed that while you have a Veritas Account, you aren't yet registered to manage cases and use chat. This is what you usually will use. Extract Decryption Keys If you are using passphrase in key file and using Apache then every time you start, you have to enter the password. Continuing the example, the OpenSSL command for a self-signed certificate—valid for a year and with an RSA public key—is: openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:4096 -keyout myserver.pem -out myserver.crt. That said, the problem isn't really that a pass phrase is required -- it's that OpenSSL makes your program hang while waiting for someone to type a passphrase in stdin, even in the case of a non-interactive, GUI or remote program.
