The concept behind Base64 is quite simple.Ĭonsider sending a message via binary. Recognizing that data requires to be sent in a text to ensure that it doesn't get damaged, let's consider the ways we can utilize Python in order to Base64 encode data and then decode it. Then, it will be Base64 decoded once it is received, so that the application can make use of it. In these instances, your media information will be Base64 encoded at the time it's being transmitted. They were initially designed to process text, but we expect to transmit images or other media along with the message. The most common scenario in which Base64 encoders are frequently used is on mail servers. Base64 is one of the most popular methods to convert data that is binary transformed into ASCII characters and is well-known to the majority of applications and networks. To circumvent this limitation, you could encode your data in text, which increases the probability of it being sent and processed properly. For example, 10110001 needs to be handled differently depending on whether it is an image or a letter. This is due to the significance of the meaning of a sequence of 0s and 1s depending on the kind of data it is representing. However, certain communications channels and programs cannot comprehend the entirety of data they receive. Why do we use Base64 Encoding?Ĭomputers transmit all information of various types is transmitted as 1s and 0s. MIME standard to transmit information other than plain text. This is among the methods employed to implement MIME. One way of encoding the digital data binary in a manner that doesn't cause transmission issues is to transmit it as simple ASCII data with a Base64 encoded form. The requirement for Base64 encoders stems from the issues that arise when media is transferred in binary format and raw to systems that use text.īecause systems that use text (like emails) take binary information in a wide variety of characters, including special characters for command, a lot of the data transferred to media for transfer is misinterpreted by these systems and is lost or damaged during the process of transmission. When a system converts Base64 characters into binary, every Base64 character represents six bits of data. + and/or / for the creation of New lines (some implementations might employ different characters) The name for this encoding originates from the base definition in mathematics - 64 characters represent the numbers in Base64.
In mathematics, the basis of a system of numbers refers to how many characters represent numbers. What exactly is Base64 Encoding?īase64 encoding is a form which converts bits to ASCII characters. We'll then apply Python for Base64 encoding and decoding binary and text data.

In this article, we will discover how Base64 encodes and decodes and how to be utilized. By encoding data, we increase the chance of it being properly processed by different systems. It is the Base64 process of encryption is employed for binary data such as video or images and is transmitted through systems specifically designed to transmit information in plain-text (ASCII) form.Įncoding Base64 lets us convert binary or text data into ASCII characters. In order to decode or encode Base64 online, enter or paste the data in the input field and click the desired button from the options "Encode Base64" or "Decode Base64".What Is Base64 Encoding? How Does Base64 Encoding And Decoding Work?īase64 encoding is the process of converting binary data into the ASCII string format, by converting the binary data into the character representation of 6-bits. Therefore 64 characters are chosen that are both members of a subset common to most encodings (ASCII), and also printable. What is the meaning of Base64?īase64 encoding schemes are used when binary data needs to be stored or transferred as textual data. Base64 is designed to carry data stored in binary formats across channels that only reliably support text content. Three 8-bit bytes (i.e., a total of 24 bits) can therefore be represented by four 6-bit Base64 digits. Each non-final Base64 digit represents exactly 6 bits of data. The term Base64 originates from a specific MIME content transfer encoding.
