Base64 is used commonly in a number of applications including email via MIME, and storing complex data in XML and in while sending usernames and passwords over network for authentication.īelow javascript snippet lets you to encode and decode your strings using Base64. In computer programming, Base64 is a group of binary-to-text encoding schemes that represent binary data in sequences of 24 bits that can be represented by. There is also a higher chance of it being corrupted while being. This is because the raw bytes may be interpreted incorrectly due to the different protocols involved in the Network. We cannot transfer Binary data over a Network in its raw format. This is to ensure that the data remains intact without modification during transport. We will be using the FileReader API to convert Blob to a Base64 Encoded String in JavaScript. Text is first converted from JavaScript UCS-2 string encoding to UTF-8. Especially when you have some special characters. Encode and decode text to/from base64 and base64url, as per RFC-4648. Decoding string in Javascript encoded in PHP by base64encode() function, can output unwanted results. Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. Simply Home Contact Calculations JavaScript base64/base64url encoder/decoder Source Code. In order to get to know them better, I suggest looking at the examples on this page. Also, some objects have methods for encoding their values to Base64.
The Base64 term originates from a specific MIME content transfer encoding.īase64 encoding schemes are commonly used when there is a need to encode binary data that needs be stored and transferred over media that are designed to deal with textual data. If you have binary data that you need to encode to pass to the client as JSON, you can convert it to base64, a common means on the Internet to represent. Text is first converted from JavaScript UCS-2 string encoding to UTF-8. JavaScript provides two built-in functions ( btoa and atob) to encode data to Base64 and decode it.
#Javascript base64 encoding code
Code for Base64 Encoding and Decoding of String – Javascriptīase64 is a generic term for a number of similar encoding schemes that encode binary data by treating it numerically and translating it into a base 64 representation.
