A binary-to-text encoding is encoding of data in plain text. More precisely, it is an encoding of binary data in a sequence of printable characters . These encodings are necessary for transmission of data when the communication channel does not allow binary data (such as email or NNTP ) or is not 8-bit clean .
uuencoding is a form of binary-to-text encoding that originated in the Unix programs uuencode and uudecode written by Mary Ann Horton at the University of California, Berkeley in 1980, [1] for encoding binary data for transmission in email systems.
The GNU shar utility produces a single file out of many files and prepares them [clarification needed] for transmission by electronic mail services, for example by converting binary files into plain ASCII text. A shell archive is a collection of files that can be unpacked by the Bourne shell. A wide range of features provide extensive ...
Base64 is often used to embed binary data in an XML file, using a syntax similar to <data encoding="base64">…</data> e.g. favicons in Firefox's exported bookmarks.html. Base64 is used to encode binary files such as images within scripts, to avoid depending on external files. Base64 can be used to embed PDF files in HTML pages. [15]
Binary or Intel hex: .obj , .obl , [ 8 ] .obh , [ 8 ] .rom , .eep Intel hexadecimal object file format , Intel hex format or Intellec Hex is a file format that conveys binary information in ASCII text form, [ 10 ] making it possible to store on non-binary media such as paper tape , punch cards , etc., to display on text terminals or be printed ...
yEnc is a binary-to-text encoding scheme for transferring binary files in messages on Usenet or via e-mail.It reduces the overhead over previous US-ASCII-based encoding methods by using an 8-bit encoding method. yEnc's overhead is often (if each byte value appears approximately with the same frequency on average) as little as 1–2%, [1] compared to 33–40% overhead for 6-bit encoding methods ...
Ascii85, also called Base85, is a form of binary-to-text encoding developed by Paul E. Rutter for the btoa utility. By using five ASCII characters to represent four bytes of binary data (making the encoded size 1 ⁄ 4 larger than the original, assuming eight bits per ASCII character), it is more efficient than uuencode or Base64, which use four characters to represent three bytes of data (1 ...
dd is a command-line utility for Unix, Plan 9, Inferno, and Unix-like operating systems and beyond, the primary purpose of which is to convert and copy files. [1] On Unix, device drivers for hardware (such as hard disk drives) and special device files (such as /dev/zero and /dev/random) appear in the file system just like normal files; dd can also read and/or write from/to these files ...
