What level of encryption was chosen for TW's SJCL?

It did indeed! The answer is aes 128 in ccm mode!

@sukima

This looks like the default is: AES 128 in CCM mode. I’d say that is pretty good! IIRC this is the same default for Mac Encrypted Disk Images.

Now if you wanted I don’t think it would be too difficult to modify the TiddlyWiki source to increase that to 256 but even then I don’t think it would matter too much.

That being said, I’m going to look into what sukima mentioned and try to change it to aes 256.

SJCL was integrated into TiddlyWiki 5 in September 2012 in this commit. I chose SJCL because it was the most widely used and trusted open source JS cryptographic library at the time. Nowadays one might be tempted to use the new browser crypto APIs but it’s actually convenient for TW to have the same code available on the server and in the browser.

Honestly, I think the right choice was made in choosing SJCL.
