Using CHCHA20 crypto functions (STM32 CryptoLib 3.1.5) Hello everyone,I was wondering the proper way to use the STM32_CHACHA_20_Encrypt() and STM32_CHACHA_20_Decrypt() functions available on the ST CryptoLib. I run the standard demo code on a STM32F072C8 MCU and it apparently run correctly, returning PASSED on the Buffercmp() that compares the function outputs to the expected const arrays declared statically.Then I wrote a small code snipped, to encrypt a 'Test' buffer and decrypts it in sequence:--------------------- Plaintext[0] = 'T'; Plaintext[1] = 'e'; Plaintext[2] = 's'; Plaintext[3] = 'T'; // Encrypt status = STM32_CHACHA_20_Encrypt( (uint8_t *) Plaintext, 4, Key, IV, sizeof(IV), OutputMessage, &OutputMessageLength); // Copy encrypted output into Plaintext buffer for(idx=0;idx<4;idx++) Plain
