How to recurse encrypt files

[Bob Metelsky]

Hi All

    Undoubtabley this has been discussed before but...

How can I encrypt all files in a directory? Im not sure how the file
names woould be recreated but possibley  just changing the file
extension

eg
myfile.txt
myfile2ddd.txt
soeotherfile.txt

would become
myfile.enc
myfile2ddd.enc
soeotherfile.enc

Can this be done?

FOR %a in (dir) do encrypt.bat *.* /s /c

but I would need to pass an alternate filename / entension to
encrypt.bat

eg [encrypt.bat]
gpg --output doc.gpg --encrypt --recipient blake@cyb.org doc

Thanks
bob
