The Base16, Base32, and Base64 Data Encodings
RFC 4648, “The Base16, Base32, and Base64 Data Encodings”, is a Proposed Standard document published in October 2006 by S. Josefsson. It obsoletes RFC 3548. The canonical text is published by the RFC Editor.
Abstract
This document describes the commonly used base 64, base 32, and base 16 encoding schemes. It also discusses the use of line-feeds in encoded data, use of padding in encoded data, use of non-alphabet characters in encoded data, use of different encoding alphabets, and canonical encodings. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
