Hi all, posted this in the Android/OpenVPN Connect form, no answers.
I've googled this and searched these fourms, and wanted to confirm with others: it appears OpenVPN Connect on Android 1.1.17 does not connect when using the new 'tls-auth' option. I've tried the exact same client configuration file on windows, linux, and the OpenVPN for Android app and they all connect correctly. So the issue seems to be OpenVPN Connect.
Can anyone else confirm?
The server error message (from two different android devices, one on android 6 and one on android 7, both using OpenVPN Connect) is:
tls-crypt unwrap error: packet too short
TLS Error: tls-crypt unwrapping failed from [AF_INET]x.x.x.x:34258

[/oconf]Hi,
I have an OpenVPN server running at home.
It works fine when HMAC auth is not configured (ie it uses SHA1) but if I try to use SHA256 or SHA512 I get 'TLS Error: cannot locate HMAC in incoming packet from xxx.xxx.xxx.xxx' server errors when I try to connect with my android phone.
Does OpenVPN Connect support HMAC auth?
Server.conf:Client.conf:
Any ideas?

While pre-1.5 versions of OpenVPN generate 1024 bit key files, any version of OpenVPN which supports the direction parameter, will also support 2048 bit key file generation using the -genkey option. License key for rocket league. (snip) -key-direction Alternative way of specifying the optional direction parameter for the -tls-auth. When setting up a tls-crypt-v2 group (similar to generating a tls-crypt or: tls-auth key previously): 1. Generate a tls-crypt-v2 server key using OpenVPN's ``-tls-crypt-v2-genkey server``. This key contains 2 512-bit keys, of which we use:. the first 256 bits of key 1 as AES-256-CTR encryption key ``Ke``.

Server.conf:Client.conf:
Code: Select all
Sftp public and private key. Ssh-keygen -t rsa -N ' Note: During key generation, SSH will check to see if there is a.ssh folder underneath the user's home directory. If one does not exist, the folder will be created in the user's home directory and the public/private key pair will be stored in it. Add a new public key to the list Under Advanced Options on the Create Server page, click Manage SSH Keys. Select public key for the cloud server from the SSH Keys list and click Add Public Key. Enter the key name, select the region, and paste the entire public key into the Public Key field. To generate the public/private key pair, enter this in the Command Prompt: ssh-keygen At the first prompt, “Enter file in which to save the key,” press Enter to save it in the default location.
This configuration works, but as soon as I uncomment the 'auth SHA512' or 'auth SHA256' in both files I get 'TLS Error: cannot locate HMAC in incoming packet from client IPOpenvpn Tls Server
' errors in the server log and the client times out.Openvpn Tls Version
Any ideas?
