Overview ¶

Package fileutil provides cross-platform secure file operations. On Unix, these are thin wrappers around the standard os functions. On Windows, owner-only modes (perm & 0077 == 0) additionally set a DACL restricting access to the current user.

Functions ¶

func SecureChmod ¶

func SecureChmod(path string, perm os.FileMode) error

SecureChmod changes the mode of the named file. On Windows, owner-only modes get a restrictive DACL.

func SecureMkdirAll(path string, perm os.FileMode) error

SecureMkdirAll creates a directory path and all parents that do not yet exist. On Windows, owner-only modes get a restrictive DACL.

func SecureOpenFile ¶

func SecureOpenFile(path string, flag int, perm os.FileMode) (*os.File, error)

SecureOpenFile opens the named file with specified flag and permissions. On Windows, owner-only modes with O_CREATE get a restrictive DACL.

func SecureWriteFile ¶

func SecureWriteFile(path string, data []byte, perm os.FileMode) error

SecureWriteFile writes data to the named file, creating it if necessary. On Windows, owner-only modes get a restrictive DACL.
