CryptUnprotectMemory Decrypts memory that was encrypted using the CryptProtectMemory function.
CryptUpdateProtectedState Migrates the current user's master keys after the user's security identifier (SID) has changed.

Structures

CRYPT_INTEGER_BLOB The CryptoAPI CRYPT_INTEGER_BLOB (dpapi.h) structure is used for an arbitrary array of bytes. It is declared in Wincrypt.h and provides flexibility for objects that can contain various data types. (CRYPT_INTEGER_BLOB)
CRYPTPROTECT_PROMPTSTRUCT Provides the text of a prompt and information about when and where that prompt is to be displayed when using the CryptProtectData and CryptUnprotectData functions.
