This is a working example on how to store CryptoKeys locally in your browser. We are able to save the objects, without serializing them. This means we can keep them not exportable (which might be more secure?? not sure what attack vectors this prevents).

To try out this example, first make sure you are in a browser that has support for async...await and indexedDB (latest chrome canary with chrome://flags "Enable Experimental Javascript" works). Load some page and copy and paste this code into the console. Then call encryptDataSaveKey(). This will create a private/public key pair and encrypted some random data with the private key. Then save both of them. Now reload the page, copy in the code, and run loadKeyDecryptData(). It will load the keys and encrypted data and decrypt it. You should see the same data logged both times.

Paprika doesn't have their API documented, so this is me reverse-engineering it from an Android device

Sync

OS X iMessage (Messages) database merger

Use it at your own risk! You might end up worse than before. Backup everything beforehand. Twice.

If you have the Messages app setup in multiple Macs with the same Apple ID you may end up with iMessages (or SMS) scattered around all of these Macs. This is because after a certain time the new iMessages (or SMS) recevied will cease to push to devices afer a certain time has elapsed. Thus, if a computer has been offline for some period of time it won't get the new iMessages.

Each Messages instance stores the information in a SQLite database, to consolidate all these databases run the script below. This is where the Messages app stores the SQLite database under ~/Library/Messages, the folder contents will look like as follows:

chat.db

The basics

This is a collection of basic "recipes", many using twurl (the Swiss Army Knife for the Twitter API!) and jq to query the Twitter API and format the results. Also, some scripts to test or automate common actions.

Hexadecimal color code for transparency

How to set transparency with hex value ?

For example, you want to set 40% alpha transparence to #000000 (black color), you need to add 66 like this #66000000.
