When do you use a base64 encoding scheme?
Base64 encoding schemes are commonly used when there is a need to encode binary data, especially when that data needs to be stored and transferred over media that are designed to deal with text. This encoding helps to ensure that the data remains intact without modification during transport.
Why is there no padding in Base64 data?
From a theoretical point of view, the padding character is not needed, since the number of missing bytes can be calculated from the number of Base64 digits. So if this is really the only thing “wrong” with your base64 data, the padding can just be added back.
Is there a way to ignore garbage in base64?
If you’re doing this on a mac, your version of base64 might not have the flexibility to handle ignoring garbage. If you brew install coreutils, you’ll have the gbase64 utility and use it as Joe has described. Thanks for contributing an answer to Stack Overflow!

What is the purpose of base64 content transfer?
The Base64 Content-Transfer-Encoding is designed to represent arbitrary sequences of octets in a form that is not humanly readable. The encoding and decoding algorithms are simple, but the encoded data are consistently only about 33 percent larger than the unencoded data.
When to use binary or 8bit Content Transfer Encoding?
If the body contains binary data, the “binary” Content-Transfer-Encoding token must be used. The distinction between the Content-Transfer-Encoding values of “binary,” “8bit,” etc. may seem unimportant, in that all of them really mean “none” — that is, there has been no encoding of the data for transport.
How to convert a string to Base64 in Node.js?
The simplest way to convert a string to Base64 encoded format in Node.js is via the built-in Buffer class. Learn how to Base64 Encode binary data in PHP.
