NCRYPT_KEY_BLOB_HEADER structure

The NCRYPT_KEY_BLOB_HEADER structure contains a key BLOB. This structure is used by the NCryptExportKey and NCryptImportKey functions.

Syntax

typedef struct _NCRYPT_KEY_BLOB_HEADER {
  ULONG cbSize;
  ULONG dwMagic;
  ULONG cbAlgName;
  ULONG cbKeyData;
} NCRYPT_KEY_BLOB_HEADER, *PNCRYPT_KEY_BLOB_HEADER;

Members

cbSize

The size, in bytes, of this structure.

dwMagic
