SSL File transfer Question Any Hints!!

Question

Hey all, i need to write code to implement this. Vert recently learned the basics behind java. Any hints how to get started. Please

the micro-SSL protocol
A asks B for B?s public key (RSA)
B responds with the public key (n,e)
A uses (n,e) to RSA-encrypt a symmetric (block cipher) key (k), giving (K)
A sends (K) to B
B acknowledges receipt of (K)
B uses the private key (n,d) to decrypt (K) giving (k)
A opens the file to be sent
A sends message to B to open a new file
B opens a new file
B acknowledges receipt of message
Repeat
A gets next block of data from file
A encrypts this by XORing with k
A sends result to B
B acknowledges receipt of encrypted block
B decrypts by XORing with k
B writes decrypted block to file
Until no more blocks to send
A closes input file
A sends message to B to finish
B closes output file
B acknowledges receipt of message
B finishes
A finishes
NOTE: For convenience in doing the calculations, you can restrict the number sizes as follows:
? Factors p,q 8 bits
? Modulus n 16 bits, leading bit 1
? k 16 bits, picked at random
? File type text, either 7 bit ASCII or 16 bit Unicode
? File blocks 16 bits
? B?s public key (n,e) and private key (n,d) can be set up in advance
