NAME

Win32::Security::EFS - Perl interface to functions that assist in working with EFS (Encrypted File System) under Windows plattforms.

SYNOPSIS

use Win32::Security::EFS;

if(Win32::Security::EFS->supported()) {
	Win32::Security::EFS->encrypt('some/file');
	Win32::Security::EFS->decrypt('some/file');
}

DESCRIPTION

The Encrypted File System, or EFS, was introduced in version 5 of NTFS to provide an additional level of security for files and directories. It provides cryptographic protection of individual files on NTFS volumes using a public-key system. Typically, the access control to file and directory objects provided by the Windows security model is sufficient to protect unauthorized access to sensitive information. However, if a laptop containing sensitive data is lost or stolen, the security protection of that data may be compromised. Encrypting the files increases security in this scenario.

METHODS

supported()

Returns true iff the underlaying filesystem supports EFS

encrypt($filename)

The encrypt function encrypts a file or directory. All data streams in a file are encrypted. All new files created in an encrypted directory are encrypted.

decrypt($filename)

The decrypt function decrypts an encrypted file or directory.
