The Secure Boot Loader (SBL) is a kernel device that handles security and cryptography. It loads the Secure Modules. This kernel device checks PUP Updates, executables, NPDRM (Retail) Packages and Debug Packages (the last 3 are handled by the Auth Manager Secure Module). It also has a system interface for Playstation File System keys and an interface for the ZLIB hardware system (/dev/sce_zlib).
