[Bug] Card writer dosen't write accurate data

[Asmoyed]

Describe the bug Mag card data write dosen't work, I'm trying to write encoded data with the component data from OC, but the data on the does not match the result from the encryption function

In which environment did the Bug appear? Singleplayer

To Reproduce Encrypt a string with OC encrypt function Write the result onto a mag card Read the data of the card Result and card data arent equal

Expected behavior The encrypted data should be properly written onto the card

Screenshots / Code Snippet

component = require("component")
writer = component.os_cardwriter
data = component.data
reader = component.os_magreader
key = data.random(128)
iv = data.random(16)
writer.write(data.encrypt("test",key,iv),"Test Card")
_, _, _, cardData = event.pull("magData")
print(cardData == (data.encrypt("test",key,iv))

Additional context Nothing more to say

The cardwriter writes Strings while the data component probably returns an byte Array. Cant really test it right now as your test script wont work for me at all.

Could you try to convert the data with component.data.encode64(data) before writing it and decoding it after reading with component.data.decode64(data) that might work around the issue

It seems to be working Thanks ^^

Closing this as it seems to be resolved.
