For data in transit that's probably fine, but for data at rest, you have to consider how long that data might remain at rest. If you have 30 year old encrypted data that is now breakable, is that a problem? It depends on the use case. Also keep in mind that any data in transit could be tapped and saved and become data at rest. So really you have to ask yourself, is it critical that this data remain encrypted in 20 years?
