We have extended wolfSSL’s Renesas Secure Crypto Engine (SCE) support to include a crypt-only build for the Renesas RA6M4. wolfSSL already supports Renesas SCE for TLS communication. In addition to our existing TLS support, the SCE driver can be used for standalone cryptographic operations. Using this mode, users are able to gain not only the performance benefit but also a smaller footprint by enabling only necessary cryptography operations. This use case was added for RA6M4 support in wolfBoot.
To enable this use case, define the macro:
WOLFSSL_RENESAS_SCEPROTECT_CRYPTONLY
wolfSSL crypt-only SCE mode currently supports SHA2-256, RSA 1024/2048 bit encryption/decryption, and RSA 1024/2048 bit sign/verify.
