wolfBoot is wolfSSL’s own implementation of a secure bootloader that leverages wolfSSL’s underlying wolfCrypt module to provide signature authentication for the running firmware. The role of a secure bootloader is to effectively prevent the loading of malicious or unauthorized firmware on the target. Additionally, wolfBoot provides a fail-safe update mechanism, that can be interrupted at any time, and resumed […]

At wolfSSL we have had customers asking us whether we support the Ed25519 signature algorithm using a hash.
