Fwd: Windows command line to decrypt multiple files

[bj]

Hi.  Good catch.  I previously did not need to supply a password to
encrypt.  I know the password, just not sure where to define it with
GPG4Win or other method.  Even though the server is internal, I want it to
be secure.  I could lock down file permissions if that helps.
When I try #2, it gives me the following   usage: gpg [options] [filename]
I still get this putting the file at the end.
Thanks, BJ

passwort is (implicitly) defined in the keyring. The secret key is stored
encrypted. You need the passphrase in order to use the key. You must know
the
passphrase, you cannot get it from the GnuPG installation.

I am not familiar with that DOS / Windows stuff. Just a few comments:

1) You do not need a passphrase when you encrypt files. You need the
passphrase for signing and decrypting.

2) ECHO Password|
gpg --passphrase-fd 0 --batch -o "..." --decrypt %%F
should do.
