Other Base64 variations share the same property but they use different symbols in the last two values. If you are decoding a binary file, use the Decode. The Base64 implementation in MIME uses a-z, A-Z and 0-9 for the first 62 values. Encodes or decodes a string so that it conforms to the Base64 Data Encodings specification (RFC 4648). This mixture leaves the data impossible to be altered in transportation thru information systems, such as electronic mail, that were typically not 8-bit clean. The common concept is to select a set of 64 characters that is both part of a subset typical to most encodings. The specific set of characters chosen for the 64 characters needed for the base can vary among implementations. Base64 is generally used in a number of applications including electronic mail via MIME, and keeping complex information in XML. This guarantees that the data stays unchanged without modification during transfer. Types of URI charactersīase64 encoding schemes are generally used when there is a need to encode binary information that needs to be stored and transferred over media that are developed to deal with textual information. Basically, Base64 is a collection of related encoding designs which represent the binary information in ASCII format by converting it into a base64 representation. The term Base64 is coming from a certain MIME content transfer encoding. Note: if you have large Base64 string (above 1mb) use the Base64 to file tool to upload the data as a file and decode it. ![]() Example: Enter the following encoded string 'YmFzZTY0IGRlY29kZXI=', hit the decode button and you will get 'base64 decoder' as output.The output will appear in a new field below the button.They are intended to be a pair of applications allowing. Input your Base64 encoded data into the input field. The following applications invoke the tcllib base64 encoding/decoding package.This tool is useful for debugging and testing the decoding process, as well as for gaining a better understanding of how Base64 decoding works. This ensures that the data remains intact without modification during transport.Our online Base64 decode tool helps you to convert encoded data that has been encoded using the Base64 encoding scheme into its original form. ![]() Buffer objects are similar to arrays of integers from 0 to 255. When the term "Base64" is used on its own to refer to a specific algorithm, it typically refers to the version of Base64 outlined in RFC 4648, section 4, which uses the following alphabet to represent the radix-64 digits, alongside = as a padding character: ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/Ī common variant is "Base64 URL safe", which omits the padding and replaces +/ with -_ to avoid characters that might cause problems in URL path segments or query parameters.īase64 encoding schemes are commonly used to encode binary data for storage or transfer over media that can only deal with ASCII text (or some superset of ASCII that still falls short of accepting arbitrary binary data). You can decode any Base64 encoded data using the built-in Buffer API provided by Node.js. The term Base64 originates from a specific MIME content transfer encoding.
