Hi,
I have been following the tutorial under Mac OS.
When entering the studio, I get this error, following the docker image pull:
```
$ hab studio enter
hab-studio: Creating Studio at /hab/studios/src (default)
hab-studio: Importing amiez secret origin key
» Importing origin key from standard input
✗✗✗
✗✗✗ Crypto error: Unsupported key version: ✗✗✗
✗✗✗
```
I used my name as origin first, tried with ‘myorigin’ too, and using the -k flag with both keys, but I always get that error.
The hab setup step went without error, I didn’t set up Github creds.

Hello -
Which key did you specify when you ran
> hab setup
An easy way to tell is by listing the files in `/hab/cache/keys` or `$HOME/.hab/cache/keys` and looking for something besides `core-*`

I created a key named `amiez` (seen in OP’s command output) then tried with one named `myorigin` (set as default with hab setup) then tried to use both of them with -k flag, always with the same outcome.
Keys in my .hab:
```auto
amiez-20160616154929.pub
amiez-20160616154929.sig.key
myorigin-20160616160311.pub
myorigin-20160616160311.sig.key
```

That error occurs when Habitat tries to verify the content of the key that's passed in [0].
Public signing keys _must_ start with a line containing `SIG-PUB-1`, and secret signing keys must start with a line containing `SIG-SEC-1`.
Can I see the permissions on the keys you listed above? Also, are you using bash or zsh in OSX?

All 4 keys have mode 0400, and directories above are 0755.
Both private keys are starting with `SIG-SEC-1`, and public keys with `SIG-PUB-1`.
I’m using zsh shell.
Thanks!

Ok, I’m wondering if zsh is causing issues here. Can you see if this works in bash? I’ll try on my end as well.

Unfortunately, I get the same error using bash…

I didn’t find any issues with zsh vs bash either.
I just noticed that you mention `Keys in my .hab`
The path for keys is `$HOME/.hab/cache/keys` or `/hab/cache/keys` [0].

I am also getting same result.

Hi Vikas -
It looks like the code that’s exporting the key into the studio can’t find your root keys.
Can you respond with the output of `ls -la` in `/hab/cache/keys` and `$HOME/.hab/cache/keys`?
Additionally, can you paste the “origin” value from `/hab/etc/cli.toml`? Note, this file may contain your Github auth key, so careful with copy/pasting in a public forum.
Cheers -
Dave

Hello Dave.
```ruby
ls -la /hab/cache/keys
total 12
drwxr-xr-x. 2 root root 4096 Jun 24 13:13 .
drwxr-xr-x. 6 root root 4096 Jun 24 13:13 ..
-rw-r--r--. 1 root root 75 Jun 24 13:13 core-20160612031944.pub
```
```ruby
ls -la $HOME/.hab/cache/keys
ls: cannot access /root/.hab/cache/keys: No such file or directory
```
```ruby
cat /hab/etc/cli.toml
origin = "root"
```
I am missing something? I am following [https://www.habitat.sh/tutorials/getting-started-create-plan/](https://www.habitat.sh/tutorials/getting-started-create-plan/)
I ran `"hab setup"` with:
**Origin name** = root
**Key for origin** = _nil_
**Github access token** = _nil_
Thanks,
Vikas

Hello Vikas -
I forgot to ask, can you run those commands in OSX instead of the Linux container?
Cheers -
Dave

Sorry Dave, I do not have OSX.
Also, just FYI.
While setting up habitat and before running **make** command I had to install:
**libsodium**
**libarchive**
On both ubuntu 14.04 and CentOS 6.8
Will this be a good idea to document it for ease of others? Just asking, it may not be that important or trivial step/understood.
Thanks,
Vikas

Hello Vikas -
The team is using an Ubuntu container in Docker with this configuration [0], which we should add to the README at some point. I’ll make a note to do so, or I’ll happily review a PR if you beat me to it 🙂

Dave
