can you explain how to do this problem step by step

2. Obtain my certificate from Files->cs166teacher.cer. Using my public key, decrypt the file "hw4.rsa" and submit what was in that file. Note: my encryption mode: RSA/ECB/NoPadding". Note: the hw4.rsa has been Base64 encoded. First you need to Base64 decode it to get a byte array, Note: when you decrypt, you may see a lot of leading O in the output. Please trim them out and submit only the text message.
