Security on Symbian OS enables data confidentiality, integrity and @ref authentication; secure comms protocols 

(for example, @ref SSL, @ref TLS, @ref WTLS, @ref IPSec, @ref SMIME "S/MIME"); and technology to support application 

signing. It provides APIs for standard cryptography and @ref hash algorithms, key generation, 

certificate management, and random number generation.

@ref Security_intro provides a quick basic overview on Public Key Cryptography, Certificates, and Digital Signatures, 

that Security APIs support. However, for detailed explanations refer to any of the standard security books available 

(for example, Applied Cryptography by Bruce Schneier).

For an overview of how the various security components are structured in the Symbian OS, see @ref Security_arch_overview.
