+ 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.
