What encryption algorithm is used? (AES-128, AES-256, CAST5, DES)

Asked by andrey_campbell

You might say that this has been answered here:

- but it's not answered.

Merely saying that it's symmetric encryption does not answer the question.

Just repeating that person's question: "GnuPG has many cipher suites, modes and key sizes. Which cipher suite, mode and keysize is used from GnuPG to encrypt the data files ?"

I wouldn't trust Deja Dup to encrypt my data with a weak encryption algorithm. There are hundreds of symmetric encryption algorithms, and I could come up with one in just 10 lines of code (that could be cracked in 2 minutes).

So again: what encryption algorithm is used, and how can I control which one from the many GnuPG supports is being used?

To clarify further: Duplicity has many parameters that can be used to control the encryption algorithm used by GnuPG. So the better question to ask is: which of the many algorithms Duplicity knows about (from the ones supported by GnuPG) is being used, and how can I control that?

Deja Dup uses the default in GnuPG, which as of this writing is CAST5. This can't be changed via Deja Dup.

Can you help with this problem?
