This paper focuses on how to achieve the end-to-end secure e-mail system of the internet. First,we have achieved adigital envelope. By combining with the characteristics of the AES and RSA message is encrypted by AES key which is encrypted by RSA,and becomes more secure. This way solves the symmetric algorithm key delivery. Second,we have achieved data integrity. By the irreversibility of the MD5 algorithm,e-mail fingerprintcan ensure the integrity of the message data. Lastly,secure e-mail system is achieved. Basing on SMTP and POP3 mail protocol,we have developed the e-mail encryption and decryption transmission system.
