VITASDK_BUILD_ASSERT_EQ() [1/2]

VITASDK_BUILD_ASSERT_EQ	(	0x18	,
		SceSblDmac5EncDecParam
	)

sceSblDmac5EncDec()

int sceSblDmac5EncDec	(	SceSblDmac5EncDecParam *	param,
		SceUInt32	command
	)

Execute DMAC5 encdec command.

Parameters

[in]	param	- Operation parameters. The destination and IV buffers they point to are written.
[in]	command	- The DMAC5 encdec command.

Returns

0 on success, else < 0.

sceSblDmac5EncDecKeyGen()

int sceSblDmac5EncDecKeyGen	(	const SceSblDmac5EncDecParam *	param,
		SceUInt32	key_id,
		SceUInt32	command
	)

Execute a user-mode DMAC5 cipher operation using an AuthMgr-derived key.

The calling process must be a system program. Key sizes of 128 and 256 bits are supported on FW 3.60. A 192-bit size passes this wrapper's validation but is rejected by the AuthMgr key loader. CBC and CTR operations read their 16-byte IV from SceSblDmac5EncDecParam::iv and replace it with the updated IV.

Parameters

[in]	param	- Required operation parameters. The structure is only read; the destination and IV buffers it points to are written.
[in]	key_id	- AuthMgr key identifier.
[in]	command	- DMAC5 cipher command word.

Returns

0 on success, < 0 on error.

sceSblDmac5HashTransform()

int sceSblDmac5HashTransform	(	SceSblDmac5HashTransformParam *	param,
		SceUInt32	command,
		SceUInt32	flags
	)

Execute DMAC5 hash transform command.

Parameters

[in]	param	- Operation parameters. The destination and context buffers they point to may be written.
[in]	command	- The DMAC5 hash base command.
[in]	flags	- Bitwise OR of SceSblDmac5HashFlag values. Use 0 for a complete one-shot operation, 0x400 for the first streaming chunk, 0xC00 for an intermediate chunk, and 0x800 for the final chunk.

Returns

0 on success, else < 0.

sceSblDmac5HmacKeyGen()

int sceSblDmac5HmacKeyGen	(	const SceSblDmac5HashTransformParam *	param,
		SceUInt32	key_id,
		SceUInt32	command,
		SceUInt32	flags
	)

Execute a user-mode keyed DMAC5 hash operation using an AuthMgr-derived key.

The calling process must be a system program and SceSblDmac5HashTransformParam::src must be 0x40-byte aligned. The key size must be 128 or 256 bits. SHA-family commands use a 0x28-byte SceSblDmac5HashTransformContext; AES-CMAC uses a 0x10-byte SceSblDmac5AesCmacContext.

Parameters

[in]	param	- Required operation parameters. The structure is only read; the output and context buffers it points to may be written.
[in]	key_id	- AuthMgr key identifier.
[in]	command	- DMAC5 hash or MAC command word.
[in]	flags	- Bitwise OR of SceSblDmac5HashFlag values.

Returns

0 on success, < 0 on error.
