SSL or TLS encryption: what's the difference?

The differences between SSL and TLS encryption are not big, since TLS is the "successor" of SSL. For example, if you have to choose one of the methods when setting up an e-mail program, you should opt for TLS as it is more secure. You can find out why in this practical tip.

SSL and TLS encryption in comparison

SSL is an "outdated" standard and continues to operate under the name TLS. The last SSL version was 3.0, which is why you may also find TLS 1.0 on the Internet as SSL 3.1. In contrast to the last SSL version, TLS has the following functions:

• Pseudo random function: Your transmitted data is harder to listen to.
• Key Exchange: TLS uses the Digital Signature Standard and the Diffie-Hellmann algorithm as the key exchange. SSL, on the other hand, uses algorithms based on Fortezza. The algorithms that TLS uses are more difficult for attackers to decrypt and therefore more secure.
• Shared protocols: With TLS, the protocols are divided into record, handshake, change, cipher, spec and alert protocols. Since an attacker needs all the protocols, it is more difficult to intercept and reassemble the individual parts. Greater security is guaranteed.
• Master Secret: Different and more complex calculation bases than with SSL, which makes your data harder to intercept and decrypt.
