The openssl implementation layers a lot of complexity with the "BIO" stuff that's not (IMHO) very useful if all you're doing is decoding/encoding. As you can see, there is no $ sign at the end of that string, hence no new line. BIO_flush() on a base64 BIO that is being written through is used to signal that no more data is to be encoded: this is used to flush the final block through the BIO. Because of the format of base64 encoding the end of the encoded block cannot always be reliably determined. There's probably a cleaner/better way of doing this (I'd like to get rid of reinterpret_cast). Why is 51.8 inclination standard for Soyuz?

Connect and share knowledge within a single location that is structured and easy to search. Because xxd ignores any trailing newline in the input, echo or echo -n will behave precisely the same here; whether there's a newline by echo makes no difference, because that newline (if it exists) will be consumed by xxd when reading its input.
