❔ X509 Certificate from base64 string
Hey man, I am here but probably won’t remember much about what I ended up doing with this certificate thing. I believe I switched the lib I was using to decode it

❔ X509 Certificate from base64 string
binary data shows that the c# one has more than 64 bytes of data while java ones always have exactly 64 bytes and 90 chars

I'm using it already somewhere else in this project, you're telling me to use it for encryption using the public key?

yeah, will request the Java dude to hand me the input public key + user info and output of the java one for me to try and replicate in c# and compare byte data then..

yeah, the userBytes is later encoded using Base64 in Java it woudl go like this: 
Base64.getEncoder().encodeToString(userBytes)
Base64.getEncoder().encodeToString(userBytes)
which probably uses the default encoding of the platform in C# it probably also uses a default encoder but they may differ 
string identifier = Convert.ToBase64String(userBytes)
string identifier = Convert.ToBase64String(userBytes)

but your guess sounds about right as it was double the size

❔ X509 Certificate from base64 string
c# 
using (RSACryptoServiceProvider RSA = ImportPublicKey(authResponse.PublicKey))
{
    byte[] userBytes = RSA.Encrypt(Encoding.UTF8.GetBytes(user), false);
using (RSACryptoServiceProvider RSA = ImportPublicKey(authResponse.PublicKey))
{
    byte[] userBytes = RSA.Encrypt(Encoding.UTF8.GetBytes(user), false);
byte[] userBytes = encryptCipher.doFinal(user.getBytes(StandardCharsets.UTF_8));
byte[] userBytes = encryptCipher.doFinal(user.getBytes(StandardCharsets.UTF_8));
you mean before encrypting or after?

I tried using it directly but it ends up creating a different sized RSA encrypted string
