unsigned int	identifier	The identifier specified for _sceNpDrmPackageCheck but NOT ORed with (1 << 8)

Function Documentation

VITASDK_BUILD_ASSERT_EQ()

VITASDK_BUILD_ASSERT_EQ	(	0x10	,
		_sceNpDrmPackageDecrypt_opt
	)

_sceNpDrmPackageCheck()

int _sceNpDrmPackageCheck	(	const void *	buffer,
		SceSize	size,
		int	zero,
		unsigned int	identifier
	)

Read the header of the PKG and initialize the context.

Parameters

buffer	- The buffer containing the header of PKG.
size	- The size of buffer. The minimum confirmed value is 0x8000.
zero	- Unknown. Supposed to be set to 0.
identifier	- arbitrary value [0, 6) ORed with (1 << 8) or 0. If it is set to 0, the function just checks the header and doesn't create the context.

Returns

0 on success, != 0 on error

_sceNpDrmPackageDecrypt()

int _sceNpDrmPackageDecrypt	(	void *__restrict__	buffer,
		SceSize	size,
		_sceNpDrmPackageDecrypt_opt *__restrict__	opt
	)

Decrypt a PKG.

Parameters

buffer	- The buffer containing the content of the PKG.
size	- The size of the buffer. The minimum confirmed value is 0x20.
opt	- The options.

Returns

0 on success, != 0 on error
