3. How can I do Base64 encoding in Node.js? - Stack Overflow

   stackoverflow.com/questions/6182315

   Buffers can be used for taking a string or piece of data and doing Base64 encoding of the result. For example: > console.log(Buffer.from("Hello World").toString('base64')); SGVsbG8gV29ybGQ= > console.log(Buffer.from("SGVsbG8gV29ybGQ=", 'base64').toString('ascii')) Hello World The Buffer constructor is a global object, so no require is needed ...

4. How do I encode and decode a base64 string? - Stack Overflow

   stackoverflow.com/questions/11743160

   Remember base64 is primarily intended for representing binary data in ASCII, for storing in a char field in a database or sending via email (where new lines could be injected). Do you really want to take character data, convert it to bytes, then convert it back to character data, this time unreadable and with no hint of what the original ...

5. Creating a Blob from a base64 string in JavaScript

   stackoverflow.com/questions/16245767

   The atob function will decode a base64-encoded string into a new string with a character for each byte of the binary data. const byteCharacters = atob (b64Data); Each character's code point (charCode) will be the value of the byte. We can create an array of byte values by applying this using the .charCodeAt method for each character in the ...

   stackoverflow.com/questions/37046771

   If you have OpenSSL for Windows installed you can use this to encode the string "Hello": echo | set /p="Hello" | openssl base64. The | set /p= is to suppress the newline that echo usually outputs. This will produce the same result as the following in bash: echo -n 'Hello' | openssl base64. Output: SGVsbG8=.

   import base64 b = base64.b64encode(bytes('your_string', 'utf-8')) # bytes base64_str = b.decode('utf-8') # convert bytes to string Explanation: The bytes function creates a bytes object from the string "your_string" using UTF-8 encoding. In Python, bytes represents a sequence of bits and UTF-8 specifies the character encoding to use.
