I need an efficient (read native) way to convert an ArrayBuffer to a base64 string which needs to be used on a multipart post.
I have following Python code to encrypt (RSA) input value using PyCrypto. Now I need to encode the encrypted value in
Base64. I tried the following and I gives me following error:
a bytes-like object is required, not 'tuple'
How to get the encoding done correctly for Base64?
from Crypto.PublicKey import RSAkey = RSA.generate(4096)f = open('C:/Test/my_rsa_public.pem', 'wb')f.write(key.publickey().exportKey('PEM'))f.close()f = open('C:/Test/my_rsa_private.pem', 'wb')f.write(key.exportKey('PEM'))f.close()f = open('C:/Test/my_rsa_public.pem', 'rb')f1 = open('C:/Test/my_rsa_private.pem', 'rb')key = RSA.importKey(f.read())key1 = RSA.importKey(f1.read())x = key.encrypt(b"MyTest",32)print(x)z = key1.decrypt(x)print(z)from base64 import b64encode, b64decodemret = b64encode(x)
this is the encoded string
i want to generate UUID for this
I want to achieve Base64 URL safe encoding in C#. In Java, we have the common
Codec library which gives me an URL safe encoded string. How can I achieve the same using C#?
byte toEncodeAsBytes = System.Text.ASCIIEncoding.ASCII.GetBytes("StringToEncode");string returnValue = System.Convert.ToBase64String(toEncodeAsBytes);
The above code converts it to Base64, but it pads
==. Is there is way to achieve URL safe encoding?
I am encoding the URL suffix of my application:
$url = 'subjects?_d=1';echo base64_encode($url);// Outputsc3ViamVjdHM/X2Q9MQ==
Notice the slash before 'X2'.
Why is this happening? I thought base64 only outputted A-Z, 0-9 and '=' as padding? I have tried using an online base64 encoder to check, and it seems base64 always does this. I can't tell if it's the underscore "_" or the question mark "?" or the "=" perhaps?
