Why does the "salt must be an 8-octet string" error occur?

Question

OpenSSL

I did everything according to this manual, except:

encrypted = encrypter.update 'top secret document'
encrypted << encrypter.final

Didn't write it.
As a result, it swears at this line:
encrypter.pkcs5_keyivgen pass_phrase, salt
Error:

salt must be an 8-octet string

I don't understand what she means.
I use this salt:

N0YIYm3wAJrhwsl3b41PPKOzmatYEbvay0dZDaUSC48D2040uB01tfklFO7SsSrJ

Если изменить на соль и примера, то все нормально. Что нужно? Почему мою соль не принимает?
