这个是哪里有问题，加密出来结果不对～

#include <mbedtls/aes.h> mbedtls_aes_context aes; unsigned char key[] = "1234567890123456"; unsigned char iv[] = "1234567890123456"; String bla = "testme"; unsigned char out[16]; unsigned char inp[16]; int size = sizeof(bla); for (int i = 0; i < size; i++) { inp[i] = bla[i]; } for (int i = size; i < 16; i++) { inp[i] = 0; } mbedtls_aes_init(&aes); mbedtls_aes_setkey_enc(&aes, key, 128); mbedtls_aes_crypt_cbc(&aes, MBEDTLS_AES_ENCRYPT, 16, iv, inp, out);
