What is the difference between SSL and SASL?

SSL stands for Secure Sockets Layer and is an encryption standard developed by Netscape to secure web communication.

Web browsers use SSL to secure the HTTP protocol in communications with web servers. This works because the data travels through a tunnel that is encrypted, providing a safe channel.

The SSL protocol was originally meant to provide confidentiality and authentication. Authentication is the part that requires some kind of credential. It means that a user will be identified when connecting to a web site using the SSL protocol.

SSL is not a protocol itself but it's often used as a protocol on top of TCP or other protocols. SASL is short for Security Assertion Markup Language, which was developed by Netscape to allow clients to authenticate to servers. The idea was that SSL alone would only provide authentication. In order to have a conversation between two parties, some kind of authorization is needed. This authorization could be based on a user account or based on a certificate. SASL was designed to let users specify what type of authority they want to connect with, how much authority, and what information to authenticate with.

The way SASL works is that it negotiates with the server what will be allowed to happen in terms of the authorization. The client chooses which methods to authenticate with, and the server can then decide whether or not it accepts the credentials. It's up to the client and server to agree on the authentication method. Clients that support SASL will negotiate the authentication methods they will accept, and servers that support SASL will negotiate what methods they accept.

An SSL certificate provides the public keys of the server. Each SSL certificate has a name, like * It identifies which organization owns the website, it shows the company's name and which SSL certificate is signed by the company. An SSL certificate also contains the domain name (the name of the website).

An SSL certificate is a kind of public key infrastructure (PKI) certificate. This means that it proves that the server belongs to the company that has issued it. The certificate may also contain the organization's legal name, a legal address, and the phone number for the company's telephone.

One part of the certification is the public key that identifies the company.

What is the difference between Kerberos and SASL?

Answer.

There is a big difference.

Kerberos: Kerberos is an application of authentication for UNIX and other related systems. It's protocol is based on key distribution with encryption, and it works well with networked computers. Kerberos uses TGTs (Token Grants to TGTs) for authentication

SASL: SASL is an authentication protocol, not Kerberos. Its purpose is to authenticate any application and/or system, not just the services being offered by Kerberos. Its primary application is used by applications such as ftp clients, mail agents, web servers, and text editors.

Why is SASL better than Kerberos? Kerberos is the most secure standard protocol. Its primary strength comes from its cryptographic methods. The weakness in Kerberos lies in its key distribution methods. In the event the keys are compromised the security of any client or service relying on Kerberos becomes questionable.

Unlike Kerberos, which requires a network to be able to run its protocol. How does SASL work? SASL, like Kerberos, uses cryptograms but SASL uses different approaches. SASL is a protocol, not a network mechanism. This means that SASL supports the ability of an application to perform authenticated operations without network connectivity.

Why should we use SASL over Kerberos? Kerberos and SASL both have their strengths and weaknesses. As stated above, SASL does not need to be a part of the network and Kerberos requires one. It is suggested that, if Kerberos is the desired authentication protocol, then SASL should be excluded from the network. If you must use Kerberos, SASL should be configured such that Kerberos and SASL co-exist safely together. The problem with co-existing kerberos and sasl with the application layer, is that the user data sent across the network might not be properly authenticated.

How do we configure SASL? You configure SASL using the saslauthd command.
