Question

I’m newbie in base64. I made some tests. I saw some stranges

When I encode “Nguyen Tran Viet A” by Terminal, it produce:

vietiPhone:~ vietnt$ echo "Nguyen Tran Viet A" | openssl enc -base64
Tmd1eWVuIFRyYW4gVmlldCBBCg==

But then I ran some libs ( in Objective-C), it produce:

Tmd1eWVuIFRyYW4gVmlldCBB

Which is right?

Thank you!

Answer 1

echo produces an EOL at end of output, so it gets encoded with OpenSSL. Try the -n option:

$ echo -n "Nguyen Tran Viet A" | openssl enc -base64
