将base64字符串解码为十进制字符串

Question

I have a string say FhY= which has been encoded to hex. So when run

>>> b6 = 'FhY='
>>> b6.decode('base64')
'\x16\x16'

This is a hex string that once converted should be 22 22 . This result has been proven on the site https://conv.darkbyte.ru/ . However, I cannot seem to do a proper conversion from base64 to decimal representation. Some of the challenges I am facing are

1. Expectation of decimal being an int. I just want base 10
2. Incorrect values. I have tried the following conversions base64 > base16 ( Convert a base64 encoded string to binary ), base64 > binary > decimal ( Convert hex string to int in Python ) both of which have failed.

Please assist.

Answer 1

You need to convert each byte from the decoded string to its decimal value. So this should solve it:

b6 = 'FhY='
' '.join([ str(ord(c)) for c in b6.decode('base64') ])

Results in 22 22
