Hello, I am using the STM32 Cryptolib. I need to get the modulus and exponent of RSA public key from a .pub or .pem files. After decoded from base64 I need to decode the DER format (in ASN.1 format). Has anyone any suggestion of which libray may I us...
For some reason bootloader fails to pass image tag authentication. SE_AuthenticateFW_Finish(pSeStatus, fw_tag_output, (int32_t *)&fw_tag_len). returns SFU_SUCCESS status. However, compare to the tag retrived from image header located in MCU flash is ...
