# SSH/SFTP For Embedded Systems

this project provides a code template, a ssh protocol template and sftp demonstrations, based on prechin's dev board, mcu stm32f103ze, peripherals ESP8266-1S(link with usart3), SD card(link with SDIO)

## prerequisites

only tested on the board with mcu stm32f103ze; required flash > 165KB case !USE_CRYPTO_V2 else > 48KB; ram size > 44 KB, peripherals ESP8266-1S(a module with ESP8266 chip) and SD card, mcu pins SDIO/SPI(not impl) for SD card and usart3 for ESP8266-1S

## how-to-use

compile by the .uvprojx project file, or use the free-to-use toolchain ARMCLANG from scratch

## references

3rd parties include HAL/CMISIS, FatFS, FreeRTOS, IOLIbrary(unused), with some files derived from OpenSSH. license MIT, which is compatible. see [LICENSES.md](./LICENSES.md).
