[Gpg4win-users-en] Unable to Preset Passphrase in GPG Agent

[robcoscia at comcast.net]

HI Bernhard, 

  

Thank you for replying to my message. 

  

I did try some of your suggestions.  I was able to successfully decrypt a file manually using the command line with pinentry. But I noticed that there was an error when the agent tried 

to write the passphrase to the cache. See the log below:

I also installed the latest version of GPG4Win version 2.2.4 but I still get the same error as above. 

  

Thanks,

thanks for your report!

Note that another solution could be to use an empty passphrase.

Two things you could check 

* Does it work in the regular way, e.g. manuel decryption via the command line and pinentry? 

* Does the current version 2.2.4 make a difference? 

  

Best, 

Bernhard
