The encrypted structure can only be decrypted by the same process. Calling the function with this option is equivalent to calling SspiEncryptAuthIdentity. This option is used to protect an identity buffer that is being persisted in a process's private memory for an extended period.

This buffer is the output of the SspiEncryptAuthIdentityEx function.
If the function succeeds, it returns SEC_E_OK.
