What is meant by Email encryption?

Email encryption refers to the process of converting the content of an email message into an encrypted code to ensure confidential communication between sender and recipient. This ensures that third parties intercepting the email cannot read the content without the corresponding decryption key.

Typical functions of software in the field of email encryption may include:

Encryption algorithms: The software provides various encryption algorithms such as AES (Advanced Encryption Standard) or RSA (Rivest-Shamir-Adleman) for securely encrypting email contents.
Key management: The ability to generate, manage, and exchange encryption keys to enable secure communication between sender and recipient.
Digital signatures: The software supports the use of digital signatures for authenticating senders and verifying the integrity of email contents.
Integration with email clients: The software can seamlessly integrate with common email clients to enable encryption and decryption of emails directly from the email client's user interface.
Key exchange protocols: Support for secure protocols such as PGP (Pretty Good Privacy) or S/MIME (Secure/Multipurpose Internet Mail Extensions) for securely transmitting encryption keys between sender and recipient.
User management: The ability to manage user accounts and permissions for accessing encrypted emails, including the ability to use different encryption keys for different users.
