The SBL (that might stand for Secure Block, as in PS Vita) device is a PS5 kernel device that handles security and cryptography. It can provides services through IOCTL. It contains the Secure Modules.
The SBL device verifies and decrypts PUP files, and associated formats like watermarks through the pup_mgr Secure Module.
It verifies and loads SELF and PRX executables, NPDRM packages and Debug packages through the auth_mgr_sm Secure Module.
It is used to obtain Individual Data (i.e. per-console, per-account, etc.) through the individual_data_mgr Secure Module. It may also be related to VTRM.
It manages the Manufacturing Mode through the manu_mode_mgr Secure Module.
It also has a system interface for PFS keys and an interface for the ZLIB hardware system (/dev/sce_zlib) through the key_mgr or auth_mgr_sm Secure Modules.
It contains the sm_service Secure Module that probably controls the load of other Secure Modules.
These Secure Modules are usually loaded from the Serial Flash, and the data they manage is also often stored encrypted on the Serial Flash. Reading the raw Serial FLash can be done by the icc IOCTL commands but obtaining decrypted content relies on SBL IOCTL commands.
