Does JSON need to be Base64 encoded?

The JSON format natively doesn’t support binary data. The binary data has to be escaped so that it can be placed into a string element (i.e. zero or more Unicode chars in double quotes using backslash escapes) in JSON. An obvious method to escape binary data is to use Base64.

What is Base64 encoding used for?

Base64 encoding schemes are commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with ASCII. This is to ensure that the data remain intact without modification during transport.

What type of encoding is Base64?

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. The term Base64 originates from a specific MIME content transfer encoding.

How can you tell Base64 encoding?

Encoded data will always have the following characteristic:

1. The length of a Base64-encoded string is always a multiple of 4.
2. Only these characters are used by the encryption: “A” to “Z”, “a” to “z”, “0” to “9”, “+” and “/”

Can we pass byte array in JSON?

json now lets you put a byte[] object directly into a json and it remains readable. you can even send the resulting object over a websocket and it will be readable on the other side.

Does base64 always end in ==?

A more complete answer is that a base64 encoded string doesn’t always end with a = , it will only end with one or two = if they are required to pad the string out to the proper length.

What is base64 Python?

In Python the base64 module is used to encode and decode data. First, the strings are converted into byte-like objects and then encoded using the base64 module. The below example shows the implementation of encoding strings isn’t base64 characters. Example: import base64.

Is base64 encoding unique?

The short answer is yes, unique binary/hex values will always encode to a unique base64 encoded string. BUT, multiple base64 encoded strings may represent a single binary/hex value.

Why does base64 end with ==?

A Base64 ends with either = or == or any of the accepted Base64 digit [A-Za-z0-9+-]. The = is a padding that indicates the number of actual bytes of data in the last three bytes.
