This web application uses a combination of CAPICOM 2 and signed Java applet
technologies to demonstrate digital signature generation, signature verification, enveloping (encryption to recipients)
and deenveloping (decryption by recipients) of arbitrary win32 files (binary or text files) from within the browser context.
Select a file to either sign, verify, envelope or decrypt, or type a target file path.
Select any of Sign, Verify, Envelope or Decrypt File. To sign a file, you must have
a certificate with associated private key in your "Personal" (or "My") win32 certificate store.
The Detached Signature checkbox determines if the p7s signature includes the original file contents. To
verify detached content signatures, a dialog prompts for the original source file.
To envelope
a file, you must have at least one public S-MIME certificate in the your "Other People" (or "AddressBook")
certificate store (files are enveloped in binary format). Typically,
these certificates are automatically made available when you receive signed email from colleagues. If there
is more than one certificate in the AddressBook, a Select Certificate dialog will be presented.
Only the owner of the private key, associated with the recipient's public key can decrypt the enveloped
file.
Both the signing and enveloping here generate binary DER pkcs7 output files. However, the verification
of signatures and decryption of enveloped files supports both binary and base64 formats, including content
signed as unicode data bytes.
File selection dialog starts in the Desktop directory. Output files have the default name "_javasciPK7".
