'what does it mean, or what is Cg== [closed]

Could someone tell me what Cg== means, I just know it's related to Base64.

I have searched but I still don't have a correct answer or an idea of ​​what it is, and I don't have much knowledge about base64

Solution 1:[1]

Cg== is the base64 encode of the new line character in the latest position. So if you want to encode ABC you will get QUJD, however if you include a "return character" after ABC you will get QUJDCg==.

Solution 2:[2]

You can use hexdump or xxd to reveal the actual value of the character in hexadecimal. In the case of Cg==, it's a linefeed (0A) which can be verified with the following:

? echo -n "Cg==" | base64 -d | hexdump -C
00000000  0a                                                |.|
00000001

Solution 3:[3]

In my experience Cg== arises from passing a string (usually credentials) to base64 using echo (without the -n switch and thus appending the default newline character at the end) rather than e.g. with printf.
