![]() ![]() ![]() However, binary-to-text encoding methods are also used as a mechanism for encoding plain text. PGP documentation (RFC 4880) uses the term ASCII armor for binary-to-text encoding when referring to Base64. These encodings are necessary for transmission of data when the channel does not allow binary data (such as email or NNTP) or is not 8-bit clean. ![]() More precisely, it is an encoding of binary data in a sequence of printable characters. Many programs perform this conversion to allow for data-transport, such as PGP and GNU Privacy Guard (GPG).Ī binary-to-text encoding is encoding of data in plain text. This process is referred to as binary-to-text encoding. Upon safe arrival at its destination, it is then decoded back to its eight-bit form. To accomplish this, the data is encoded in some way, such that eight-bit data is encoded into seven-bit ASCII characters (generally using only alphanumeric and punctuation characters-the ASCII printable characters). ![]() It is often desirable, to be able to send non-textual data through text-based systems, such as when one might attach an image file to an e-mail message. ![]()
