JavaScript Crypto Libraries

List some crypto libraries for JavaScript out there. Might be a bit out dated. Scroll to the bottom.

WebCryptoAPI

http://www.w3.org/TR/WebCryptoAPI/

This specification describes a JavaScript API for performing basic cryptographic operations in web applications, such as hashing, signature generation and verification, and encryption and decryption. Additionally, it describes an API for applications to generate and/or manage the keying material necessary to perform these operations. Uses for this API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications.

Updating Python on OS X with HomeBrew

Updating Python library with HomeBrew could be a painful experience. Upgrading setuptools and pip may cause version disruption and will render pip and easy_install useless.

Here's a list of commands for the install process, FYI.

# disable virtualenv before doing this

Setting up ssh public key authentication on macOS using a YubiKey 4

I largely followed Florin's blog post, but have a few notes to add regarding issues I encountered:

Basic setup notes

I used a YubiKey 4, while the blog describes using a YubiKey NEO. I'm sure a YubiKey 5 would also work. I'm also running macOS 10.13.6.
I installed GPGTools as recommended. However, as I'll note later, it seems that gpg-agent only automatically starts when gpg is used; for ssh, you'll need to ensure it's running.
Before generating your keys, decide what key size you want to use. If you run the list command inside gpg --edit-card, look for the Key attributes line to see what is currently selected. On my YubiKey 4, it defaulted to 2048 bits for all keys:

Key attributes ...: rsa2048 rsa2048 rsa2048

Mattermost OAuth2.0 endpoints

{mattermost_url} = your Mattermost instance url

https://{mattermost_url}/oauth/authorize # auth_url
https://{mattermost_url}/oauth/access_token # token_url
https://{mattermost_url}/api/v4/users/me # so-called api_url

Notes

Note: PBSS in Geth >=1.13.0 removes the need to prune manually.

Overview

Geth (Go-Ethereum) as of July 2022 takes about 650 GiB of space on a fast/snap sync, and then grows by ~ 14 GiB/week with default cache, ~ 8 GiB/week with more cache.

-# delete local tag '12345'
-git tag -d 12345
-# delete remote tag '12345' (eg, GitHub version too)
-git push origin :refs/tags/12345
-# alternative approach
-git push --delete origin tagName
-git tag -d tagName

	# remove specific file from git cache
	git rm --cached filename

	# remove all files from git cache
	git rm -r --cached .
	git add .
	git commit -m ".gitignore is now working"
