Here’s a code snippet translating a base64-encoded string to UTF8: // using the base64 encoded string from aboveĬonst plain = om('dXNlcm5hbWU6cGFzc3dvcmQ=', 'base64'). 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. Base64 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. You can create a buffer instance using the om method. Base64 is a collection of related encoding designs which represent the binary information in ASCII format by converting it into a base64 representation. This means that the Base64 version of a string or file will be at least 133 the size of its source (a 33 increase). So, three 8-bits bytes of the input string/binary file (3×8 bits 24 bits) can be represented by four 6-bit Base64 digits (4×6 24 bits). Node.js supports data encoding via the global Buffer class. 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. Encoded size increase Each Base64 digit represents exactly 6 bits of data.
