A method of providing security to transport e mails is
A method of providing security to transport emails is:
- Transport Layer Security (TLS): a cryptographic protocol that provides end-to-end encryption and authentication for email communications.
- Secure Sockets Layer (SSL): a predecessor to TLS, still used by some email providers for encrypting email communications.
- STARTTLS: an extension to the Simple Mail Transfer Protocol (SMTP) that allows for the encryption of email communications using TLS.
- DomainKeys Identified Mail (DKIM): a method of authenticating the sender of an email by using a digital signature.
- Sender Policy Framework (SPF): a method of preventing spam by verifying the authenticity of an email sender's IP address.
- Domain-based Message Authentication, Reporting, and Conformance (DMARC): a method of authenticating the sender of an email and preventing email spoofing.
- PGP (Pretty Good Privacy): a method of encrypting email communications using public-key cryptography.
- S/MIME (Secure/Multipurpose Internet Mail Extensions): a method of encrypting email communications using public-key cryptography.
- Email Encryption: a method of encrypting email communications using symmetric-key cryptography, where the same key is used for both encryption and decryption.
- End-to-End Encryption: a method of encrypting email communications using public-key cryptography, where only the sender and intended recipient have the decryption keys.
These methods provide various levels of security to protect email communications from interception, tampering, and eavesdropping.
