ENCRYPTED_CREDENTIALW

構造体
サイズx64: 88 バイト / x86: 56 バイト

サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。

フィールド

フィールドサイズx64x86説明
CredCREDENTIALW80/52+0+0暗号化対象となる資格情報を保持するCREDENTIALW構造を埋め込む。
ClearCredentialBlobSizeDWORD4+80+52暗号化前の平文資格情報ブロブのバイト数を示す。

HSP用 定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。

; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x86 レイアウト)
