module HexaPDF::Encryption::StandardSecurityHandler::Permissions

Defines all available permissions.

It is possible to use an array of permission symbols instead of an integer to describe the permission set. The used symbols are the lower case versions of the constants, i.e. the symbol for MODIFY_CONSTANT would be :modify_constant.

See: PDF2.0 s7.6.4.2
