### Sign External Bootloader Image with OpenSSL

Source: https://context7_llms

This command simulates the signing process using OpenSSL, taking an externally prepared bootloader image file (`.extsign`) and a private sign key to generate a signature file (`.der`). This signature is then used by Simplicity Commander to create the final signed bootloader image.

```bash
openssl dgst -sha256 -binary -sign sign_key.pem -out bl_signature.der bootloader-uart-xmodem.extsign

### C Address Range Check Intrinsic: cmse_check_address_range

Source: https://www.keil.com/support/man/docs/armclang_ref/armclang_ref_pge1446715440722.htm

The `cmse_check_address_range` intrinsic is used in C programming to perform permission checks on C objects by validating an address range. It requires a pointer to the start of the range, the size of the range, and a flag indicating the type of check. The intrinsic returns a pointer to the validated range on success or NULL on failure, ensuring data dependency for subsequent memory accesses.

```c
void *cmse_check_address_range(void *ptr, size_t size, int flags);
```

--------------------------------

### Sign Bootloader Image with Simplicity Commander

Source: https://context7_llms

This command uses Simplicity Commander to sign a bootloader image file (`.s37`). It takes the input bootloader image, a private sign key, and a public key for verification, then outputs a signed bootloader image. This method is suitable when not using an external signing mechanism.

```bash
commander convert bootloader-uart-xmodem.s37 --secureboot --keyfile sign_key.pem --verify sign_pubkey.pem \
--outfile bootloader-uart-xmodem.s37
```

--------------------------------

### Configure Secure Boot Settings in C

Source: https://context7_llms

Configures SE OTP (One-Time Programmable) initialization settings within the init_se_otp_conf() function in app_se_manager_key_provisioning.c. Enables secure boot, anti-rollback protection, and optionally certificate verification. Note: enabling secure boot is required for other options to take effect.

```C
// Overwrite secure boot options in SL_SE_OTP_INIT_DEFAULT if necessary.
otp_init.enable_secure_boot = true;
otp_init.verify_secure_boot_certificate = false;
otp_init.enable_anti_rollback = true;
otp_init.secure_boot_page_lock_narrow = false;
otp_init.secure_boot_page_lock_full = false;
```

--------------------------------

### Sign GBL File with Commander

Source: https://context7_llms

Signs a GBL (Gecko Bootloader) file using a specified private key and verifies it with a public key, outputting a signed GBL file. Requires the '.extsign' file, signature file, and public key for verification.

```bash
commander gbl sign blink_baremetal.extsign --signature gbl_signature.der --verify sign_pubkey.pem \
   --outfile blink_baremetal.gbl
```

```bash
commander gbl sign blink_baremetal.extsign --signature gbl_signature.der --verify bl_cert_pubkey.pem \
