How do I encrypt an excel file to a pki card or smartcard? I'd like to
make
an excel spreadsheet that only staff with a pki card can open!
You can download PGP (Pretty Good Privacy) which has a file encryption
utility, but if you want it all smaller, you can also try a simple tool that
I made a couple of years ago:
http://home.planet.nl/~timp0049/storage/mfccrypt.zip
In that 130kB zip archive you'll find 7 files:
- GPL.txt General Public License
- MFCCRYPT.exe Windows Encryption application
- W32CRYPT.exe Console Encryption application
- W32HASH.dll Password encryption (key hashing) library file / MD5, SHA1 &
SHA2
- W32CLIB.dll Encryption algorythm library / 3DES, AES & RC4
- W32VBLIB.dll 'bridge' to use key hashing and encryption libraries from
Visual Basic or VBA
- W32CRYPT.xls Sample which shows how to use libraries from Excel
* dll's should be placed in your C:\WINDOWS\SYSTEM32 folder
