Base64 1.9

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation.

Base64 was created by Joseph M. Leon and William B. Easton of Communications Associates Inc. (COMACT) in June 1984.

The purpose of using Base64 encoding is to convert binary data into a format that can be easily transmitted over the internet, such as in email or in HTML form data where characters other than A-Z, a-z, 0-9 and '+' '-' '/' cannot be reliably transmitted.

Base64 is commonly used for encoding images, audio, video, and other binary data for transmission over the internet. It is also used in cryptographic applications to represent binary data in a printable format.

No, Base64 is not encryption. It is simply a method of encoding data so that it can be transmitted over the internet more easily. It can be easily decoded by anyone who has access to the encoded data.

Base64 converts every three bytes of binary data into four bytes of ASCII text. The resulting text contains only characters from the set A-Z, a-z, 0-9 and '+' '-' '/'. When decoding, the process is reversed, with every four bytes of ASCII text convert into three bytes of binary data.

The maximum length of a Base64 encoded string is about 4/3 times the length of the original binary data. In other words, for every three bytes of binary data, four bytes of ASCII text will be generated.

Yes, Base64 can handle all types of files, including images, audio, video, and other binary data. However, it is less efficient than other encoding schemes such as gzip or bzip2.

No, Base64 is not case-sensitive. The encoding and decoding process is the same regardless of whether the letters A-Z are in upper or lower case.

Yes, there are many JavaScript libraries available for implementing Base64 encoding and decoding in web applications, such as the atob() and btoa() functions built into modern browsers.
