What is a digital envelope and how does it work?
A digital envelope is a secure online communication method that allows users to send and receive sensitive information, such as confidential documents or personal data, in a protected and encrypted environment. It works by creating a virtual “envelope” around the data being transmitted, which can only be accessed by the intended recipient using a unique decryption key. This ensures that even if the data is intercepted during transmission, it will be unreadable to anyone without the decryption key.
The digital envelope process typically involves a combination of encryption algorithms and secure protocols, such as SSL/TLS or PGP, to protect the data in transit. The sender encrypts the data using the recipient’s public key, and the recipient decrypts it using their private key. This ensures that the data remains confidential and tamper-proof throughout the transmission process. Additionally, digital envelopes often include features such as authentication and non-repudiation, which verify the identity of the sender and recipient and prevent either party from denying involvement in the transaction.
