You can then translate the encoding to a UTF8 representation. Make sure to pass the correct encoding to initialize the buffer correctly. Pass it your base64-encoded string as the first argument and the base64 encoding as the second argument. Again, create a buffer instance using the om method. Here’s a code snippet translating a string in UTF8 encoding to base64: const encoded = om('username:password', 'utf8').toString('base64')ĭecoding a base64-encoded string is also possible using the global Buffer class. Pass the value you want to base64-encode as the first argument and the current encoding as the second argument. You can create a buffer instance using the om method. Node.js supports data encoding via the global Buffer class. this encoding will also correctly accept regular base64-encoded strings. For example, we can decode R3JlYXQK as follows. Retrieve the List of Supported Hash Algorithms When decoding a Buffer into a string that does not exclusively contain valid. Conversely, we can decode the encoded data using the -decode option.

Split an Array Into Smaller Array Chunks in JavaScript and Node.js Decoding base64 to original string: The Buffer can also be used to convert the base64 string back to utf8 encoding. When the term 'Base64' is used on its own to refer to a specific algorithm, it typically refers to. The term Base64 originates from a specific MIME content transfer encoding. How to Exit and Stop a for Loop in JavaScript and Node.js 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.
