Question 1

Are the files encrypted to one key or many?

Accepted Answer

One key — every file in the batch is encrypted to the same recipient. To send different files to different recipients, run the tool multiple times.

Question 2

Does the zip get encrypted?

Accepted Answer

No — the .pgp files inside are encrypted, but the zip itself is plain (not password-protected). Anyone with the zip sees which files are inside; only the key-holder can read their contents.

Question 3

How many files can I batch?

Accepted Answer

Bounded by browser memory. Practically: a few dozen large files, hundreds of small ones. The progress indicator shows where you are.

Question 4

Does it preserve filenames?

Accepted Answer

Yes — each .pgp file in the zip uses the original filename plus the .pgp extension (so doc.pdf becomes doc.pdf.pgp).

Question 5

Can the recipient bulk-decrypt?

Accepted Answer

GnuPG can decrypt a batch via a shell loop (gpg --decrypt for each file). PGP Tool currently decrypts one at a time via File Encrypt.
