Use: "cryptdecode encryptedremote: encryptedfilename",
|
|
Short: `Cryptdecode returns unencrypted file names.`,
|
|
Long: `
|
|
rclone cryptdecode returns unencrypted file names when provided with
|
|
a list of encrypted file names. List limit is 10 items.
|
|
|
|
If you supply the ` + "`--reverse`" + ` flag, it will return encrypted file names.
|
|
|
|
use it like this
|
|
|
|
rclone cryptdecode encryptedremote: encryptedfilename1 encryptedfilename2
|
|
|
|
rclone cryptdecode --reverse encryptedremote: filename1 filename2
|
|
|
|
Another way to accomplish this is by using the ` + "`rclone backend encode` (or `decode`)" + ` command.
|
|
See the documentation on the [crypt](/crypt/) overlay for more info.
