which encryption method is best for cloud storage?

Hello,

I'm not a big fan of cloud storage and I never used it.

In the event i decide to do a test drive, here is my plan:

Create a encrypted container with cryptsetup and put my files in it,

Or

Create a tar archive of folder/files and encrypt it with GNU/GPG.

These are the only encryption methods I'm more familiar with. Are there more or stinger ones?

Thanks in advance
