| summary: Insufficient entropy in AES-256-CBC in github.com/pubnub/go |
| description: |- |
| There is insufficient entropy in the implementation of the AES-256-CBC |
| cryptographic algorithm. The provided encrypt functions are less secure when hex |
| encoding and trimming are applied, leaving half of the bits in the key always |
| the same for every encoded message or file. |
| |
| Users are encouraged to migrate to the new crypto package introduced in v7.2.0. |
