Binary-to-text encoding
open-in-new
<p> A binary-to-text encoding is <a href="/facts/Code/CSntvnEo">encoding</a> of <a href="/facts/Data_(computing)/cPjfFHph">data</a> in <a href="/facts/Plain_text/TSlSSAg2">plain text</a>. More precisely, it is an encoding of binary data in a sequence of <a href="/facts/Character_(computing)/X2zKLFFB">printable characters</a>. These encodings are necessary for transmission of data when the <a href="/facts/Communication_channel/MtlxEShV">communication channel</a> does not allow binary data (such as <a href="/facts/Email/6pD9GLtI">email</a> or <a href="/facts/NNTP/YTgxGqgR">NNTP</a>) or is not <a href="/facts/8-bit_clean/2j1DTzgg">8-bit clean</a>. <a href="/facts/Pretty_Good_Privacy/4BELG9BW">PGP</a> documentation (<a href="/facts/RFC_(identifier)/esftTvE7">RFC</a> <a href="https://www.rfc-editor.org/rfc/rfc9580">9580</a>) uses the term "ASCII armor" for binary-to-text encoding when referring to <a href="/facts/Base64/xIvVm33q">Base64</a>. </p>
