Need help in decrypting a cipher

February 26th, 2009 11:00 pm by PvsNP

Can somebody help me decrypt this cipher? Below is the cipher text encrypted with an affine cipher (mod 26). If you can decrypt it can you also tell me how you did it because I will have to explain the process to my mentor. Last resort ah ka rawn post tawp. Due date is March 5th.
