但是,由于SHA256不同,我假设这在字符串编码方面是个问题。Python使用UTF8,即使我尝试在Bash脚本中执行printf "%s" "${string}" | iconv -t utf-8 | openssl dgst -sha256, 浏览0提问于2019-02-17得票数 0 2回答 如何base64编码SHA256十六进制字符串...

However, now you can’t look at your image—unless you learn how to decode the data. Fortunately, this doesn’t require a lot of code in Python, so go ahead and create a new script file to accomplish this conversion: Python convert.py 1import json 2from base64 import b64decode 3from...
