How to Handle 26-Byte Secret for Time-based One Time Password?

Asked 2022-Apr-02 at 04:15

Secret of Time-based One Time Password are usually 16-byte base32 encoded string. e.g. GitHub 2FA.

But for some scenario, it has 26 bytes long. e.g. Tutanota OTP. Often in lower case with whitespaces, like: vev2 qjea un45 3sr4 q4h3 ais4 ci

I tried with the TOTP algorithm implemented in dgryski/dgoogauth and tilaklodha/google-authenticator. Both can handle 16-byte secret well, but got error for 26-byte secret.

e.g. for 16-byte secret VEV2QJEAUN453SR4:

Answered 2022-Apr-02 at 04:15

A base32 encodes every 5 bits of input bytes into base32 character, go base32 use The RFC 4648 Base 32 alphabet (A-Z, 2-7). When decode a string to bytes, each base32 character input will be mapped to a 5 bit index then recompose to bytes.

In your example "VEV2QJEAUN453SR4Q4H3AIS4CI", the previous "VEV2QJEAUN453SR4" was already valid input, it is a 16 char input, and 5 bit * 16 is 80 bit so it can be resolved into 10 bytes output. Now let us just look at the rest "Q4H3AIS4CI", 10 char -> 5 * 10 = 50 bits, the previous 40 bits can be decode to 5 bytes, but the last 2 char "CI" leads 2 bit remainder

Ansible SSH user change during playbook execution causes freeze

Asked 2022-Mar-02 at 08:54

I have a playbook that is launched from AWX with machine credentials, ie. with ssh_user_A. In this playbook, i need to perform a couple of tasks with another SSH user, ie. ssh_user_B.

In terms of credentials, I have:

machine credentials for ssh_user_A that are OK, I can do whatever I need
a public/private keys couple for ssh_user_B:
- the public key is present on the remote host in the ~ssh_user_B/.ssh/authorized_keys file
- if I test this public/private key with a temp machine credentials (not possible in final target) and a dummy playbook or an ad-hoc module call, it works I can do whatever I need

I've made a lot of tests and found the problem: by default, to connect to the target hosts, Ansible uses the smart connection plugin. In my case, the smart plugin leads to the use of the native OpenSSH.

Forcing manually the use of the paramiko connection plugin solves the problem, everything is OK (paramiko is a Python implementation of OpenSSH). Just need to add the instruction connection: paramiko at the needed level:

The error comes form underlying Paramiko and is discussed here:
Paramiko authentication fails with "Agreed upon 'rsa-sha2-512' pubkey algorithm" (and "unsupported public key algorithm: rsa-sha2-512" in sshd log)

Though pysftp does not expose the disabled_algorithms parameter.

You better switch to using Paramiko directly. The pysftp is abandoned project. See pysftp vs. Paramiko.

As per documentation, Authorization header should contains all the data. Your Authorization header contains only OAuth oauth_consumer_key.

Your actual header (bad format, because , for example, 'oauth' is an entry of the headers, but should be a property of Authorization - see below).

QUESTION

Paramiko authentication fails with "Agreed upon 'rsa-sha2-512' pubkey algorithm" (and "unsupported public key algorithm: rsa-sha2-512" in sshd log)

Asked 2022-Jan-13 at 14:49

I have a Python 3 application running on CentOS Linux 7.7 executing SSH commands against remote hosts. It works properly but today I encountered an odd error executing a command against a "new" remote server (server based on RHEL 6.10):

encountered RSA key, expected OPENSSH key

Executing the same command from the system shell (using the same private key of course) works perfectly fine.

On the remote server I discovered in /var/log/secure that when SSH connection and commands are issued from the source server with Python (using Paramiko) sshd complains about unsupported public key algorithm:

userauth_pubkey: unsupported public key algorithm: rsa-sha2-512

Note that target servers with higher RHEL/CentOS like 7.x don't encounter the issue.

It seems like Paramiko picks/offers the wrong algorithm when negotiating with the remote server when on the contrary SSH shell performs the negotiation properly in the context of this "old" target server. How to get the Python program to work as expected?

Imo, it's a bug in Paramiko. It does not handle correctly absence of server-sig-algs extension on the server side.

Try disabling rsa-sha2-* on Paramiko side altogether:

LinkedIn Learning LTI failed authentication

Asked 2021-Dec-23 at 01:51

I'm attempting to integrate LinkedIn Learning Single-Sign-On via an LTI connection, however I'm always faced with the response: LTI_FAILED_AUTHENTICATION.

LinkedIn Learning - LTI_FAILED_AUTHENTICATION

When I test it out on the Saltire test platform, it strangely works.

The parameters match what I am sending from the code below: Saltire LTI Success authentication

Have tried copying over the the values of oauth_nonce, timestamp and oauth_signature from Saltire to my page, and that worked also, which scores out the possibility of domain whitelisting requirement.

LinkedIn support have come back saying there seems to be something wrong with the generated signature, but I'm not sure what is wrong about it, since that is generated by the parameters passed.

Is there something incorrectly setup from my page which I am not seeing?

...

ANSWER

Answered 2021-Dec-23 at 01:51

I figured out the issue. By using the Saltire test tool, I was able to verify that my signature was generated correctly when using their testing URL: https://lti.tools/saltire/tp

You can play with an example here: https://learningcom.github.io/ltitest/index.html

So after looking at the LinkedIn URL, I discovered that the signature was getting generated with an unnecessary long URL which contained parameters.

Removed: ?application=learning&redirect=https://www.linkedin.com/learning/me

Therefore, I shortened the URL to:

var action = 'https://www.linkedin.com/checkpoint/enterprise/login/[accountID]';

No more errors!

pip install custom package from BitBucket with SSH without entering SSH password

Asked 2021-Nov-21 at 02:34

I am trying to use pip install git+ssh://git@bitbucket.org/my_org/my_package_repo.git to install a custom-made python package (shared by multiple applications) from BitBucket WITHOUT having to enter the SSH password.

There seems to be a lot of good information in one of the answers to this question for doing this in GitLab, etc. There's also some solid supporting information here.

I've already setup an SSH key between my local Mac and this BitBucket account. I'm able to push/pull code all the time to/from this account without having to re-enter the SSH password. Why is the pip install command requiring the password, when it's not required by git commands? Is there a way around this with BitBucket and the setup I've described?

When I run the GIT_SSH_COMMAND='ssh -vvv' pip install git+ssh://git@bitbucket.org/my_org/my_package_repo.git command recommended in the comments, I get the following (sanitized) response:

Your log does not show SSH require a password. But a passphrase (because the private key was created and then stored encrypted, protected by a passphrase).

That means any pip install should be done from a shell where eval $(ssh-agent); ssh-add ~/.ssh/id_rsa has been executed first, in order to cache said passphrase, and allow the all process to not require any input, for an unattended run.
