The Apple CDSA framework contains an expandable set of cryptographic
algorithms to perform code signing and encryption operations while
maintaining the security of the cryptographic keys. It also contains
libraries which allow the interpretation of X.509 certificates.

The CDSA code is used by MacOSX features such as Keychain and URL Access
for protection of login data. Many cryptographic algorithms are available
in the Apple CSP (Cryptographic Service Provider) module.
