Java is a type-safe language that has four types of security mechanisms known as the security sandbox mechanism to guarantee the security of the language, and these four types of security sandboxes are: .class File verifier

SASL defines how authentication data

authorizationsJars authorization enhances the Java security model by adding access control mechanisms based on users, groups, and roles. It allows setting withUser-level and operation-level permissions to enforce access control for code performers. The subject object created during the authentication process represents an authenticated entity. Subject objects typically contain a set of principal, where eac

Implements the ssl/i ' LS state machine (sslengine), which allows the processing of buffer data to generate ssl/i ' LS encoded data(J2SE 5.0 and later).

(). Before you call Wrap () unwrap () or beginhandshake (), you must set all configuration parameters. All of these methods trigger the first handshake. The movement of data through the engine is done by calling Wrap () (outbound data) or unwrap () (inbound data). Depending on the state of Sslengine, The Wrap () call may consume application data from the source buffer and may also generate network data in the destination buffer. Outbound data may contain application data and/or handshake data.
