Digital Envelope is one of the practices to attain the prime requirements in e-commerce channels. In this paper, we suggest a software implementation of a digital envelope for a secure e-commerce channel that combines the hashing algorithm of MD5, the symmetric key algorithm of AES and
the asymmetric key algorithm of Hyperelliptic Curve Cryptography (HECC). The result illustrates that HECC is the best alternative asymmetric key technique rather than ECC and RSA in the digital envelope hybrid cryptosystem
