title: OpenBSD Encode and Decode Base64
body: <p><a href="https://github.com/fivesmallq/web-data-extractor/blob/master/src/main/java/jodd/util/BCrypt.java#L675" rel="nofollow noreferrer">According to what I read</a>, OpenBSD seems to have its own system on encoding and decoding using Base64. However,I cant find any literature whatsoever that can describe it mathematically. my question is, what is the difference between the usual EncodeBase64 DecodeBase64 with the OpenBSD version? how do we calculate it on math?</p>
