Hi there. I have been using the wolfssl lib for a while on the freescale mcu mk82fn256xxx and the performance have been greate so far. Wc_generateSignature performs a signature within milliseconds. Recently I switched from freescale to STM mcu, SMT32F437VG serie. This mcu has a RNG, CRYPTO and HASH engine. When it comes to the wc_GenerateSignature I can make the difference between two of them. Stm mcu takes to long to perform the signature (about 4.5 seconds). Is there any way to improve the signature process? I am not sure but I think that the difference between two MCUs relies on the PKA(Public Key Accelerator). Any help is appreciated.
Regards
