7/1/2023 0 Comments Binary-to-text encoding![]() Files that contain machine-executable code and non-textual data typically contain all 256 possible eight-bit byte values. In contrast, most computers store data in memory organized in eight-bit bytes. ![]() Systems based on ASCII use seven bits to represent these values digitally. For example, the capital letter A is ASCII character 65, the numeral 2 is ASCII 50, the character } is ASCII 125, and the metacharacter carriage return is ASCII 13. The ASCII text-encoding standard uses 128 unique values (0–127) to represent the alphabetic, numeric, and punctuation characters commonly used in English, plus a selection of control codes which do not represent printable characters. ![]() PGP documentation ( RFC 4880) uses the term ASCII armor for binary-to-text encoding when referring to Radix-64. ![]() 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 characters. A binary-to-text encoding is encoding of data in plain text.
