Good practices regarding handling of cryptographic keys?

I use cryptographic keys all the time. From SSH:ing at home, to connecting to work related stuff over SSH, sending PGP encrypted mails.

All these keys and passwords for changing the keys should be protected by a single master password imho. But you can't use notes for that, because of the 10000 character limit on encrypted data. So the current solution I have is to export my keys as files, and then uploading them as attachments via the web interface (which is clumpsy).

What are the best practices for handling keys and is Bitwarden planning to integrate (cryptographic) key management into the client?

How are public/private cryptographic key pairs actually generated?

Everything I read seems to always be really heavy on simple example theory and totally empty on real world implementation. Like how does my computer know what massive primes to use? How does it even know they are prime? If there is a list of primes to use then aren't there tables that would easily break public keys?

What do you think is the secret? I think the secret is that the SNARKs are a powerful cryptographic tool that enable applications that give users unprecedented levels of oversight and privacy. They are also a key-ingredient in building scalable decentralized systems like Mina. v.redd.it/hr46rihwxum61

keys.pub: Go library to manage cryptographic keys, signing, encryption, keyring, etc.

Hi all,

I've been working on a go library to help manage cryptographic keys, and wanted to get some feedback from the community.

You can find some examples at keys.pub and the repositories at github.com/keys-pub/keys.

For example, if you need to generate and store keys in a cross platform secure keyring, or encrypt/decrypt using saltpack, or perform a handshake with noise protocol.

I'm still working on the documentation and the library is still going through changes but any feedback is welcome. Thanks!

Last week it was saying upgrading to 6.0.7 was suggested. Now it has changed to say we should be going to 6.2 branch with no mention of the other branches at all.
