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。(x64 レイアウト)
; STORAGE_CRYPTO_CAPABILITY_V2 サイズ: 32 バイト(x64)
dim st, 8    ; 4byte整数×8(構造体サイズ 32 / 4 切り上げ)
; Version : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; Size : DWORD (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; CryptoCapabilityIndex : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; AlgorithmId : STORAGE_CRYPTO_ALGORITHM_ID (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; KeySize : STORAGE_CRYPTO_KEY_SIZE (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; DataUnitSizeBitmask : DWORD (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; MaxIVBitSize : WORD (+24, 2byte)  wpoke st,24,値  /  値 = wpeek(st,24)
; Reserved : WORD (+26, 2byte)  wpoke st,26,値  /  値 = wpeek(st,26)
; SecurityComplianceBitmask : STORAGE_SECURITY_COMPLIANCE_BITMASK (+28, 1byte)  varptr(st)+28 を基点に操作(1byte:入れ子/配列)
; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。
; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
