Description

When configuring with RSA verify-only (--enable-rsavfy) and SP math (without WOLFSSL_SP_MATH_ALL), enabling ECCSI or SAKKE caused build failures.

• Updated the #if guard on sp_mont_red_ex in sp_int.c to also compile when WOLFCRYPT_HAVE_ECCSI or WOLFCRYPT_HAVE_SAKKE is defined.

Testing

Added cryptonly-rsavfy-sp-math-eccsi-sakke test config to os-check-linux.json.

Checklist

• added tests
• updated/added doxygen
• updated appropriate READMEs
• Updated manual and documentation
