Add Deterministic Random Bit Generator based on AES in Counter mode (AES-CTR-DRBG)

[mprimeaux]

A Deterministic Random Bit Generator based on AES in Counter mode (AES-CTR-DRBG) as specified in NIST SP 800-90A written in Go.

Please note this library was part of nanoid but decided to move it to its own repository along with the related prng-chacha module.

We want to ensure high quality of the packages. Make sure that you've checked the boxes below before sending a pull request.

• I have read the Contribution Guidelines
• I have read the Maintainers Note
• I have read the Quality Standards

Not every repository (project) will require every option, but most projects should. Check the Contribution Guidelines for details.

• The repo documentation has a pkg.go.dev link.
• The repo documentation has a coverage service link.
• The repo documentation has a goreportcard link.
• The repo has a version-numbered release and a go.mod file.
• The repo has a continuous integration process that automatically runs tests that must pass before new pull requests are merged.
• Continuous integration is used to attempt to catch issues prior to releasing this package to end-users.

Please provide some links to your package to ease the review

• forge link (github.com, gitlab.com, etc): https://github.com/sixafter/aes-ctr-drbg
• pkg.go.dev: https://pkg.go.dev/github.com/sixafter/aes-ctr-drbg
• goreportcard.com: https://goreportcard.com/report/github.com/sixafter/aes-ctr-drbg
• coverage service link (codecov, coveralls, etc.): https://sonarcloud.io/summary/overall?id=six-after_aes-ctr-drbg&branch=main

Pull Request content

• The package has been added to the list in alphabetical order.
• The package has an appropriate description with correct grammar.
• As far as I know, the package has not been listed here before.

Category quality

Note that new categories can be added only when there are 3 packages or more.

Packages added a long time ago might not meet the current guidelines anymore. It would be very helpful if you could check 3-5 packages above and below your submission to ensure that they also still meet the Quality Standards.

• The packages around my addition still meet the Quality Standards.

Of the packages above and below this entry, the only package that may need further review is acmetool as it has not received a commit in 3 years (January 8, 2023) as of when this PR was submitted.

Thanks for your PR, you're awesome! 😎
