Panopticon 23.3

# decryptFile()

This function removes the encryption on a protected file, giving access to the original, unencrypted file.

## Syntax

    KVPanopticonError decryptFile(
       KVPanopticonContext* const context,
       const char* const inputFilePath,
       const char* const outputFilePath
    );

## Arguments

`context` | A pointer to `KVPanopticonContext`, initialized by calling init().
`inputFilePath` | A null-terminated C string that contains the path of the file to decrypt.
`outputFilePath` | A null-terminated C string that contains the path of the output file to create. If a file already exists at this location, Panopticon overwrites it.

## Returns

If the function was successful, it returns `KVP_Success`. Otherwise, it returns a KVPanopticonError value describing the problem.

## Discussion

- To decrypt a protected file, Panopticon must make an HTTP request.

- By default, Panopticon uses the system proxy when it makes HTTP requests. You can also specify the proxy manually in the `cryptographyservices.cfg`. See Configure the Proxy for RMS.

- This function returns an error if decryption is not supported for the `inputFile` you provide. You can obtain information about the level of support provided by using encryptionInfo().
