• done
• Describe Classical encryption techniques including steganography, transposition and rotor machines (still confusing me a bit)
• done
• Describe the confidentiality issues in conventional encryption, Including placement of encryption function, traffic confidentiality, key distribution and random number generation (still confusing me)

And again any help with these? just google gives back these mad websites that dont tell you much

Refer to related docs section at the bottom of the page.

If you want a simplified description, then pls. consult the book - Computer Networks by Tanenbaum (PKC concept + overview of RSA implementation given in the book).
