This property decodes raw data into an ASCII Base64 string. I could manually strip and re-add the padding to base 64 encoded strings, but for my use case, that will be a LOT of additional string manipulation. Base64 is a notation for encoding arbitrary byte data using a restricted set of symbols that. then base64 encodes those bytes to produce a random 32-character string. It seems like Base 64 should be able to determine what the correct amount of padding was without the "=" characters being present as you can add an arbitrary number of "=" symbols to the end of a base 64 string and it will always decode successfully (at least using Python's base64.b64decode()).

A valid option would be something like a version of Base 64 that automatically determines, when decoding back to binary, whether padding was necessary. You ask in a comment what the size of encoding 123456 would be. The process encodes every 6 bits of data into one of the 64 Base64 characters, so the 24-bit input divided by 6 results in 4 Base64 characters. I've spend a lot of time looking at various encodings and was wondering, after failing to find, if there is some encoding that can produce an output less than 64 characters but without padding (just for URL cleanliness, I'd rather not have padding). The input string is 3 bytes, or 24 bits, in size, so the formula correctly predicts the output will be 4 bytes (or 32 bits) long: TWFu. Base64 is a binary-to-text encoding scheme. Base64 encoding involves converting an 8 bit binary data stream (for example. Obviously the typical encoding of choice is hex. Each Base64 digit represents exactly 6 bits of data. With this generator it is possible to generate a random base64 string. It will be put in a URL so something URL safe is preferable. I have 32 bytes of binary data that I want to encode.
