Nested Class Summary

Nested Classes
Modifier and Type	Interface and Description
`static class`	`WinCrypt.CRYPTPROTECT_PROMPTSTRUCT` The CRYPTPROTECT_PROMPTSTRUCT structure 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.
`static class`	`WinCrypt.DATA_BLOB` The CryptoAPI CRYPTOAPI_BLOB structure is used for an arbitrary array of bytes.
