config BOOT_KEY_IMPORT_BYPASS_ASN
bool "Directly access key value without ASN.1 parsing"
help
Originally public keys compiled into MCUboot are
stored in ASN.1 encoded format, Enabling the options
bypasses the ASN.1 decoding and directly accesss the key
in ASN.1 bitstream; this reduces MCUboot code by removing
the ASN.1 processing.
