2014 Q5(c)ICMP / SNMP / SecurityHash· 4 marks

I generate an MD5 message digest fingerprint of the phrase: "2012 TR3 NAAEC CNA Supp" and it produces the string 80c55979acb8198c4445c25810e4e630. I update this for next year and change this message to: "2013 TR3 NAAEC CNA Supp" What will happen to the MD5 signature? Briefly explain your answer.
