Base64 can be used to transmit and store text that might otherwise cause delimiter collision; Base64 is used to encode character strings in LDAP Data Interchange Format files; 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.
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.
The resulting string is encoded using a variant of Base64 (+/ and with padding). The authorization method and a space character (e.g. "Basic ") is then prepended to the encoded string. For example, if the browser uses Aladdin as the username and open sesame as the password, then the field's value is the Base64 encoding of Aladdin:open sesame ...
If the data is Base64-encoded, then the data part may contain only valid Base64 characters. [7] Note that Base64-encoded data: URIs use the standard Base64 character set (with '+' and '/' as characters 62 and 63) rather than the so-called "URL-safe Base64" character set. Examples of data URIs showing most of the features are:
More common today is the Base64 format, which is based on the same concept of alphanumeric-only as opposed to ASCII 32–95. All three formats use 6 bits (64 different characters) to represent their input data. Base64 can also be generated by the uuencode program and is similar in format, except for the actual character translation:
JSFuck - Write any JavaScript with 6 Characters: []()!+ – web application for encoding JavaScript to JSFuck; JavaScript code of the aforementioned converter; JScrewIt - Another tool to convert JavaScript to JSFuck, with environment-specific optimizations; Esolang - The esoteric programming languages wiki
In these cases, the header field is actually redundant for the email client to decode the message body, but it may still be useful as an indicator of what type of object is being sent. Values ' quoted-printable ' and ' base64 ' tell the email client that a binary-to-text encoding scheme was used and that appropriate initial decoding is ...
For example, a tag of 1 indicates that the following number is a Unix time value. A tag of 2 indicates that the following byte string encodes an unsigned bignum . A tag of 32 indicates that the following text string is a URI as defined in RFC 3986 .
