# Transport and message security

Two main ways of securing interactions are Secure Sockets Layer with Transport Level Security (SSL/TLS) and digital signatures.

Use SSL/TLS in environments the require both message confidentiality and integrity. For SAML messaging, digital signatures ensure the identity of both parties involved in the transaction and validate that a particular partner received a message. To achieve increased privacy, PingFederate also lets you encrypt SAML 2.0 messages, including SAML metadata files, as well as WS-Trust STS assertions.
