![]() ![]() ![]() The jinja random filter allows us to generate a random number which is close, but it still isn't quite right since I can only end up with a numeric value. The other method I've found was prompting for a password, but then a user is aware of what the password is, and I don't want users to be aware of that information. We have people using ansible in a heterogeneous environment, so trying to rely on either password or password_lookup simply won't work for us since I either have to run some string of LOCAL commands (problem because of people running ansible on different platforms), or they refer to a file (bad practice to pass around password files). So, some password must be generated and provided to the user module. But we have found that on our servers, without the password being initialized, the SSH key is always rejected. x1b2j x1b2j To generate password with the highest entropy possible with standard Linux tools that are built into every distribution I use: This outputs all of the ASCII printable characters - from 32 (space) to 126 (tilde, ). You can optimize it by replacing the 'fold', with other string processing tools. The password is a formality, the user should NEVER log in using the password, only an SSH key. It generates 10 characters random string. bcrypt uses 128 bit salts, the same is recommended for Argon2 as well.I am trying to have ansible automatically create a password for a user, but I want the password to be unknown. The user guide gives an example with only 16 bits of salt entropy - while this is still much better than no salt or a non-random salt, it doesn't provide strong protection against precomputation. Many password hashing algorithms support salts of arbitrary length, but in many cases only a few characters are used. cant find the URL anymore) on how to create a random string, combined it in the. This should still be enough to protect against rainbow table attacks, but it provides a lot less protection than larger alphabets such as. I was wondering if ansible has a way to generate a unique identifier. However, the filter only outputs plain (Python) numbers, which limits the output alphabet to the decimal digits. As all lookups, this runs on the Ansible host as the user running the playbook, and become. Empty files cause the password to return as an empty string. This can be used when you need a password without storing it on the controller. ![]() The core filter random is ideal for generating entropy as input to other filters, especially when reproducible randomness based on unique tokens such as the inventory hostname is desired. The password lookup will generate a new random password each time, but will not write it to /dev/null. ![]()
