base64给出了错误的结果

Question

Because I am setting up vnc server, I need to convert string to base64 to setup password. ( How to setup vnc password

Say, if I want my password to be qwerty , I have to place the encoded string into the password into conf file.

I see there is a base64 utility in Ubuntu. man base64 . echo qwerty | base64 echo qwerty | base64 gives cXdlcnR5Cg== . But this doesn't work.

But if I use the online base 64 tool . qwerty is encoded to cXdlcnR5 . This string WILL WORK.

Question: why the two base64 encode gives different result?

Answer 1

echo adds a '\\n' ; try echo -n

$ echo -n qwerty | base64 
cXdlcnR5
