Importing from rclone.conf did not copy the salt value

[jkt3000]

I used the import rclone.conf option when creating new crypt rclone drive but it didn’t copy the salt value, only the password.

Here’s a relevant section of my rclone.conf file.

[gcrypt]
type = crypt
remote = gdrive:/secret
filename_encryption = standard
directory_name_encryption = true
password = valuechanged
password2 = othervaluechanged

How much letters count is the password2?
It must be grater than 22 characters. If it exactly has 22 characters, password2 is null. It happened rclone/rclone#3492

[jkt3000]

My password2 value is over 30characters.

Thanks for information. I'm checking the logic around there.

[lithium0003]

The password2 field character count must be 0,2,3 mod 4.
Password/salt(password2) reveal section may fail when character count is 1 mod 4 or decoded text is not valid utf8 text.
Are there any special characters (ex. emoji) in your original password2?

[jkt3000]

Wait, did you mean the original password2 value has to be more than 22 characters or the resulting encrypted value has to be more than 22.

My original password2 is 8 characters long, the encrypted value is much longer. No special characters or emojis.

Also not sure what 0,2,3 mod 4 means

[lithium0003]

It means the encrypted characters more than 22 and the count remainder divided by 4 must not be 1.
22 means null, 23 is ok, 24 is ok, 25 is NG.
Encrypted password2 are encoded by BASE64 after encryption. Your original password2 has 8bytes means that it has 16+8=24bytes raw encrypted data, so BASE64 encoded data has 24*4/3=32 characters. 32 is just divided by 4, no remainder, this is OK.

Thanks, I find it!
This bug occurs in just divided by 4 characters. Fix it next release.
