The silly thing is that cmd requires double quotes to be escaped with double quotes (“”). now we need 6 Characters that must contain specific double quotes. Also, to allow unambiguous spaces, the string must be surrounded by qout with escape characters ( “) to avoid thisError: too many parametersParameter numbers before -n must also be enclosed in quotation marks.

However, Makecert does not help support hexadecimal values. At least I can barely figure out how to convert Escape to hexadecimal character code ( 22) should also cause double quotes.

The secret is that for cmd-specific double quotes it is necessary to mask the quotes 4 ‘6 “(” “) and that according to the X.500 / X.509 rfc2253 standard, language characters are enclosed in double quotes. price (” “”) so we need 6 Characters that form double quotes. For spaces to be a single character as well, the string must be quoted with escape characters ( “) and then avoidedError: too many parameters, it is often necessary to specify string parameters -n in quotes.

However, Makecert does not look for support for hexadecimal values. At least I couldn’t figure out how to avoid the sixteenth retreatcharacter code ( 22), and create double quotes.
