This is not a question but an FYI for those using the crypt backend.
For cloud vendors like Onedrive that have a limit on the maximum path length (not filename), when using the crypt backend, keep in mind these two:
- each segment of the path needs to be encrypted separately (for obvious reasons)
- From: https://rclone.org/crypt/ "File segments are padded using PKCS#7 to a multiple of 16 bytes before encryption."
This means that if your pathname includes a lot of components that close to a multiple of 16, but greater than it, your encrypted pathname will be way longer than that unencrypted pathname. 1-char, 17-char, 33-char etc. are the worst case scenario. Eg:
$ rclone backend encode crypted: "/a/b/c/d/e/f/g/h" | wc -c 217 $ rclone backend encode crytped: "/abcdefgh" | wc -c 28 $ rclone backend encode crypted: "/aaaaaaaaaaaaaaa/bbbbbbbbbbbbbbb/cccccccc/dddddddd/e/f/g/h" | wc -c 217
This all makes perfect sense. Just pointing it out to save others the trouble of tripping up on it.
