The name comes from the fact that it uses 64 possible characters (A-Z, a-z, 0-9, +, /) to represent data. Each Base64 character represents exactly 6 bits of the original binary data, which is why the encoded output is always about 33%…from base64converters.com

Talanoa▲345Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client.
