Today I found Duplicati couldn’t work again - this issue just happened last month, today I just found this issue caused by CCleaner, I used it yesterday, and it cleared all credentials in windows credential storage.

I have try (\*\*\*\*\*\*\*\* indicates passphrase)

Duplicati.CommandLine --passphrase \*\*\*\*\*\*\*\*  
Duplicati.CommandLine --passphrase = \*\*\*\*\*\*\*\*  
Duplicati.CommandLine --passphrase:\*\*\*\*\*\*\*\*  
Duplicati.CommandLine --passphrase=\*\*\*\*\*\*\*\*  
Duplicati.CommandLine --passphrase = ‘\*\*\*\*\*\*\*\*’  
Duplicati.CommandLine --passphrase ‘\*\*\*\*\*\*\*\*’

I wonder what format is right.
