This read-only object indicates whether the module's software supports encryption, reporting disabled(1) or enabled(2). Like its hardware-encryption sibling, the object's own description text in the MIB is a copy/paste defect describing both states as "does not support encryption," so the enumeration label itself, with enabled(2) meaning software encryption support is present, is what carries the real meaning. An admin checking whether a module can perform software-based encryption for a feature not hardware-accelerated would read this object and expect enabled(2) on a module running an encryption-capable image.
