ESP32 SHA1 on uhashlib is not correct at 2nd or more times.
I tried this, and result is not same at 1st time and 2nd or more.
is it a bug?

uhashlib module object has no attribute sha1
When using the micropython port for rp2 board, and trying to use uhashlib.sha1(), it gives error: module object has no attribute sha1. Only sha256 is implemented. Please add sha1 in uhashlib as well. I also tried to compile micropython from source, editing the file /micropython/ports/rp2/mpconfigport.h By default only #define MICROPY_PY_UHASHLIB (1) is present; i tried to add #define MICROPY_PY_UHASHLIB_SHA1 (1) but the compiling process results in this error:
