I’ve been trying a few different solutions to Base64 encode and decode a javascript Float32Array so I can send it to my Web API in a JSON doc. But every time I decode the string back to an array of float, I get a longer one than I started with. I’ve tried the following approaches… Read More Base64-decoded Float32Array is longer than the encoded one. Why?

I want convert this base64 string to a byte string like this: base64: XHhjXHg0OFx4ODNceGU0XHgwXHhlOFx4Y2NceDAwXHgwMFx4MDBceDQxXA== string byte: \xc\x48\x83\xe4\x0\xe8\xcc\x00\x00\x00\x41\ I made this code: import base64 bstring = "XHhjXHg0OFx4ODNceGU0XHgwXHhlOFx4Y2NceDAwXHgwMFx4MDBceDQxXA==" decoded = base64.b64decode(bstring) print(decoded) And this is the output: b’\\xc\\x48\\x83\\xe4\\x0\\xe8\\xcc\\x00\\x00\\x00\\x41\\’ So this is the problem. I don’t wanna double slash and b” so how can I convert it like… Read More How to convert base64 byte to string byte without extra slashes and b''

I did a lot of research and can’t seem to find the answer for this, e.g: link1 link2 So I have this base64 encoded string: BzM=, and I know that the correct value is 18.43 This value comes from a decimal field from a MySql database with the following associated definition {‘scale’: ‘2’, ‘decimal.precision’: ‘8’},… Read More Base64 Binary String representation to float convertion

I have a file that contains many lines of base64 encoded text. I usually use base64 -d command to decode a single base64 string, but can I apply this command to each line in a file? Of course I can write a simple python script for this purpose, but I’m looking for more elegant and… Read More How to decode base64 from each line in file in bash?
