Why is base64 encoding different on windows and Linux?

Question

Character encoding

I encode the string via openssl on the Win10 command line and the same string in the CentOs console. The result is different on these OSes. utf-8 encodings. Why is that?

Answer 1

direct the output in both cases to files and compare these files (look in a hexadecimal viewer), that's the point.
either the encoding is different, or someone (Windows, I suppose) puts BOM at the beginning of the line, or there is a line break (it is different in different OSes).

Answer 2

The base64 algorithm is single and unambiguous.
If the strings are different, then the input is different strings. It's most likely a coding issue. Check input strings

Answer 3

Here you can decode the string back online and understand which OS the error is on:

Win10 uses 866 encoding by default on the command line.
