This method requires the use of a
secret key ring, you have to specify the directory in which the
secret key ring resides though the KeyFolder
property. Cryptocx will automatically search through the secret ring
in the specified directory to find the required key.
You need to specify the Password
of the secret key that is needed.
You need to specify the file to
decrypt, the SourceFile.
You need to specify where the
result of decryption will go, the DestinationFile.
This method after decrypting the
file will then verify the signature, if the signature cannot be
verified, then it will not return "TRUE" even if the file
can be decrypted fine.
