Query related to encryption key size increase #1291

Closed dev-aarifsk closed 2 months ago

dev-aarifsk commented 2 months ago

Hello,

I would like to check if there are plans to allow user to choose encryption e.g. 192 bit / 256 bit.
Are there any known performance related concerns on using 256 bit? Thanks

Not in our plan. The main challenge is not about performance, with hardware acceleration, AES 128 has nearly the same speed as 256. It's the refactor / code challenge. For some optimization is tied to the size of the encryption key.

I will convert this issue to discussion as a long term feature request.
