Windows10でバイナリ<->HEXテキスト変換

はじめに

強制スクリーンセーバ設定されている会社にて、スクリーンセーバの抑制する方法を色々と考えています。
1. スクリーンセーバの起動を抑制する - アセンブラ バージョン
2. スクリーンセーバの起動を抑制する - Arduino Pro Micro(の互換機)を使用
3. スクリーンセーバの起動を抑制する - vbsバージョン
4. スクリーンセーバの起動を抑制する - mpgバージョン

上記1と4は会社にファイルを持ち込む必要がありました。Windows10でBIN<->HEX変換できるコマンドを発見しましたので、下記活用したいと思います。

コマンド

CERTUTILコマンドを使用します。

HEXエンコード

オプション -f -encodehexを指定します。

DOS:CERTUTIL ENCODE
certutil -f -encodehex keycode.exe keycode.hex 4


BINデコード

オプション -f -decodehexを指定します。

DOS:CERTUTIL DECODE
certutil -f -decodehex keycode.hex keycode.exe 4


最後の数値はテキストファイルフォーマットのオプションになります。
CryptBinaryToStringA function

オプション

変数	数値	意味
CRYPT_STRING_BASE64HEADER	0x00000000	Base64, with certificate beginning and ending headers.
CRYPT_STRING_BASE64	0x00000001	Base64, without headers.
CRYPT_STRING_BINARY	0x00000002	Pure binary copy.
CRYPT_STRING_BASE64REQUESTHEADER	0x00000003	Base64, with request beginning and ending headers.
CRYPT_STRING_HEX	0x00000004	Hexadecimal only.
CRYPT_STRING_HEXASCII	0x00000005	Hexadecimal, with ASCII character display.
CRYPT_STRING_BASE64X509CRLHEADER	0x00000009	Base64, with X.509 CRL beginning and ending headers.
CRYPT_STRING_HEXADDR	0x0000000a	Hexadecimal, with address display.
CRYPT_STRING_HEXASCIIADDR	0x0000000b	Hexadecimal, with ASCII character and address display.
CRYPT_STRING_HEXRAW	0x0000000c	A raw hexadecimal string.
CRYPT_STRING_STRICT	0x20000000	Enforce strict decoding of ASN.1 text formats. Some ASN.1 binary BLOBS can have the first few bytes of the BLOB incorrectly interpreted as Base64 text. In this case, the rest of the text is ignored. Use this flag to enforce complete decoding of the BLOB.
CRYPT_STRING_NOCRLF	0x40000000	Do not append any new line characters to the encoded string. The default behavior is to use a carriage return/line feed (CR/LF) pair (0x0D/0x0A) to represent a new line.
CRYPT_STRING_NOCR	0x80000000	Only use the line feed (LF) character (0x0A) for a new line. The default behavior is to use a CR/LF pair (0x0D/0x0A) to represent a new line.
