How Does Base64 Encoding Work?

  1. Take the ASCII value of each character in the string.
  2. Calculate the 8-bit binary equivalent of the ASCII values.
  3. Convert the 8-bit chunks into chunks of 6 bits by simply re-grouping the digits.
  4. Convert the 6-bit binary groups to their respective decimal values.

JavaScript Object Notation (JSON) is a standard text-based format for representing structured data based on JavaScript object syntax. It is commonly used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page, or vice versa).

What is base64 string?

Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. … Base64 is commonly used in a number of applications including email via MIME, and storing complex data in XML.

How do I pass images in API?

Send an Image to an API

  1. Add an Image Element to a page in your app. …

How do you send the multipart file and JSON data to spring boot?

To pass the Json and Multipart in the POST method we need to mention our content type in the consume part. And we need to pass the given parameter as User and Multipart file. Here, make sure we can pass only String + file not POJO + file. Then convert the String to Json using ObjectMapper in Service layer.

What is Base64 string example?

Base64 Encoding Example

A Base64 encoder starts by chunking the binary stream into groupings of six characters: 100110 111010 001011 101001. Each of these groupings translates into the numbers 38, 58, 11, and 41.

Why does Base64 end with ==?

The equals sign “=” represents a padding, usually seen at the end of a Base64 encoded sequence. … This leaves us with one byte (8 bits); we pad the remaining byte with two bytes with value zero and encode the last sequence. Two equal signs (“==”) are added to the encoded string.

What does a Base64 string look like?

In programming, Base64 is a group of binary-to-text encoding schemes that represent binary data (more specifically, a sequence of 8-bit bytes) in an ASCII string format by translating the data into a radix-64 representation.
