| DecryptMessage | X | X | This function decrypts a message. |
| DeleteSecurityContext | X | X | This function deletes local data structures associated with the specified security context. |
| EncryptMessage | X | X | This function encrypts a message to help provide privacy. |
| EnumerateSecurityPackages | X | X | This function retrieves an array of SecPkgInfo structures that describe the security packages available to the client. |
