PPC64 ASM: AES-ECB/CBC/CTR/GCM/XTS
To turn on assembly: --enable-ppc64-asm To build C code: --enable-ppc64-asm=inline To disable hardening (when physical access to device is not possible): WOLFSSL_PPC64_ASM_AES_NO_HARDEN AES-GCM works with either 4-bit (default) or table: --enable-aesgcm=table Using 'table' is faster for encryption/decryption.
