encode from echo

Every once in a while I am caught by forgetting echo command sends a trailing new line character. Use "-n" switch every time the result of echo is piped as input data for openssl when encoding. Here is for example the difference illustrated while encoding base64 the word 'hello':

$ echo -n "hello" | openssl enc -base64
aGVsbG8=

However when decoding you must not use the swtich '-n':

$ echo "aGVsbG8=" | openssl base64 -d
hello
