Ansible Generate_ssh_key Module
- May 29, 2017 H ow do I use Ansible to upload ssh public key to as authorizedkey to multiple Linux or Unix servers saved in an inventory file? To add or remove SSH authorized keys for particular user accounts use authorizedkey module. This quick tutorial shows how to create an Ansible PlayBook that will add public ssh keys to multiple Unix or Linux servers for login securely.
- Ansible is a radically simple IT automation engine that automates cloud provisioning, configuration management, application deployment, intra-service orchestration, and many other IT needs. Designed for multi-tier deployments since day one, Ansible models your IT infrastructure by describing how all of your systems inter-relate, rather than just managing one system at a time.
- Type1: With Ansible Shell module and Typical Commands. In this method, We are not going to use any ansible in-built module and every step is done manually by executing the shell command. The Playbook contains the following tasks. Create an SSH Private and Public Key using ssh-keygen command.
- The ansible command module does not pass commands through a shell. This means you can't use shell operators such as the pipe, and that is why you are seeing the pipe symbol in the output. As far as ansible is concerned, it has executed the command echo with all of the rest of the line as arguments to echo.
Oct 13, 2017 ISSUE TYPE Bug Report COMPONENT NAME authorizedkey ANSIBLE VERSION 2.4 SUMMARY Ansible 2.4 seems to have a bug with authorizedkey module. Here the code. Name: generate key user: name: linh5847 cr. Type1: With Ansible Shell module and Typical Commands. In this method, We are not going to use any ansible in-built module and every step is done manually by executing the shell command. The Playbook contains the following tasks.

- Adds or removes SSH authorized keys for particular user accounts.
| Parameter | Choices/Defaults | Comments |
|---|---|---|
| comment string | Change the comment on the public key. Rewriting the comment is useful in cases such as fetching it from GitHub or GitLab. If no comment is specified, the existing comment will be kept. | |
| exclusive boolean |
| Whether to remove all other non-specified keys from the authorized_keys file. Multiple keys can be specified in a single key string value by separating them by newlines.This option is not loop aware, so if you use with_ , it will be exclusive per iteration of the loop.If you want multiple keys in the file you need to pass them all to key in a single batch as mentioned above. |
| follow boolean |
| |
| key | The SSH public key(s), as a string or (since Ansible 1.9) url (https://github.com/username.keys). | |
| key_options - | A string of ssh key options to be prepended to the key in the authorized_keys file. | |
| manage_dir boolean |
| Whether this module should manage the directory of the authorized key file. If set to yes, the module will create the directory, as well as set the owner and permissions of an existing directory.Be sure to set manage_dir=no if you are using an alternate directory for authorized_keys, as set with path, since you could lock yourself out of SSH access. |
| path | Alternate path to the authorized_keys file. When unset, this value defaults to ~/.ssh/authorized_keys. | |
| state string |
| Whether the given key (with the given key_options) should or should not be in the file. |
| user string / required | The username on the remote host whose authorized_keys file will be modified. | |
| validate_certs boolean |
| This only applies if using a https url as the source of the keys. If set to no, the SSL certificates will not be validated.This should only set to no used on personally controlled sites using self-signed certificates as it avoids verifying the source site.Prior to 2.1 the code worked as if this was set to yes. |
Common return values are documented here, the following are the fields unique to this module:
| Key | Returned | Description |
|---|---|---|
| exclusive boolean | success | If the key has been forced to be exclusive or not. |
| key string | success | Sample: |
| key_option | success | Key options related to the key. |
| keyfile string | success | Sample: |
| manage_dir | success | Whether this module managed the directory of the authorized key file. True |
| path string | success | |
| state | success | Whether the given key (with the given key_options) should or should not be in the file present |
| unique boolean | success | |
| user | success | The username on the remote host whose authorized_keys file will be modified user |
| validate_certs boolean | success | This only applies if using a https url as the source of the keys. If set to no, the SSL certificates will not be validated.True |

More information about Red Hat’s support of this module is available from this Red Hat Knowledge Base article.
When I have developed it last year, I wanted to create the ECC key in the Android Keystore. Unfortunately, this ECC key is used to generate a session key thanks to ECDH, and ECDH is not supported by Android Keystore (this is what I have been said here: ECDH with key in Android Key Store ). To generate the key, use a KeyPairGenerator with KeyPairGeneratorSpec: /. Generate a new EC key pair entry in the Android Keystore by. using the KeyPairGenerator API. The private key can only be. used for signing or verification and only with SHA-256 or. SHA-512 as the message digest. Generate ecc key pair android app. Android™ Examples.

When using a ECDHE ciphersuite you'll need to generate a ephemeral key pair as well, but this is hidden in the TLS implementation. Fortunately generating ECC key pairs is relatively fast: just randomization and point multiplication. This is one of the main benefits of using ECC.
