Error: Null check operator used on a null value; in PaddedBlockCipherImpl.process

[SalatielMG]

Dear pointycastle team,

I am using the PaddedBlockCipherImpl class from your library and have encountered an issue when using the "process" function. I receive the following error:

Null check operator used on a null value

After reviewing the code, I identified that the issue is due to the lack of null safety checks on lines 52, 53, 56, and 86. I have created a new branch locally with a proposed solution for this problem, ensuring the necessary null checks are implemented. However, I do not have permissions to push this branch to the repository.

I would greatly appreciate it if you could review the email ("Request for Permission to Create a New Branch in pc-dart for Null Safety Issue Fix") I sent requesting permissions so that I can push the changes and subsequently create a PR, which you might consider for integration or improvement in a future release of the library.

Thank you for your attention and for the excellent work you do with pointycastle.

Best regards, Salatiel Montero.

Hello,
I think the best would be, that you provide a PR. Once the PR is ready and looks good, I will merge the PR. I am currently checking all open PRs and issues and try to get as many done as possible and then release a new version on pub.dev.

Hello, thank you.
Thanks @Ephenodrom

I have created the following PR 254 where I send the proposed solution for the implementation of null safety in PaddedBlockCipherImpl. I hope you can review, integrate, or improve it soon.

I look forward to your response. Best regards.
