SCE_DNAS_USER_DATA_MAX_LEN

#define SCE_DNAS_USER_DATA_MAX_LEN   2048

Maximum size of a source buffer in byte.

Function Documentation

sceDdrdbDecrypt()

s32 sceDdrdbDecrypt	(	u8 *	pSrcData,
		SceSize	size
	)

Decrypt the provided data. The data has to be AES encrypted.

Note

The used key is provided by the PSP.

Parameters

pSrcData	Pointer to data to decrypt. The decrypted data will be written back into this buffer.
size	The size of the data to decrypt. The size needs to be a multiple of KIRK_AES_BLOCK_LEN. Max size: SCE_DNAS_USER_DATA_MAX_LEN.

Returns

0 on success, otherwise < 0.

sceDdrdbEncrypt()

s32 sceDdrdbEncrypt	(	u8 *	pSrcData,
		SceSize	size
	)

Encrypt the provided data. It will be encrypted using AES.

Note

The used key is provided by the PSP.

Parameters

pSrcData	Pointer to data to encrypt. The encrypted data will be written back into this buffer.
size	The size of the data to encrypt. The size needs to be a multiple of KIRK_AES_BLOCK_LEN. Max size: SCE_DNAS_USER_DATA_MAX_LEN.

Returns

0 on success, otherwise < 0.

sceDdrdbHash()

s32 sceDdrdbHash	(	u8 *	pSrcData,
		SceSize	size,
		u8 *	pDigest
	)

Generate a SHA-1 hash value of the provided data.

Parameters

pSrcData	Pointer to data to generate the hash for.
size	The size of the source data. Max size: SCE_DNAS_USER_DATA_MAX_LEN.
pDigest	Pointer to buffer receiving the hash. Size: KIRK_SHA1_DIGEST_LEN.

Returns

0 on success, otherwise < 0.

sceDdrdbMul1()

s32 sceDdrdbMul1

(

u8 *

pKeyData

)

Generate a new (public,private) key pair to use with ECDSA.

Parameters

pKeyData

Pointer to buffer receiving the computed key pair. The first KIRK_ECDSA_PRIVATE_KEY_LEN byte will contain the private key. The rest of the bytes will contain the public key (elliptic curve) point p = (x,y), with the x-value being first. Both coordinates have size KIRK_ECDSA_POINT_LEN / 2.

Returns

0 on success, otherwise < 0.

sceDdrdbMul2()

s32 sceDdrdbMul2	(	u8 *	pPrivKey,
		u8 *	pBasePoint,
		u8 *	pNewPoint
	)

Compute a new elliptic curve point by multiplying the provided private key with the
provided base point of the elliptic curve.

Parameters

pPrivKey	Pointer to the private key of a (public,private) key pair usable for ECDSA.
pBasePoint	Pointer to a base point of the elliptic curve. Point size: KIRK_ECDSA_POINT_LEN
pNewPoint	Pointer to a buffer receiving the new curve point. Buffer size: KIRK_ECDSA_POINT_LEN

Returns

0 on success, otherwise < 0.

sceDdrdbSigvry()

s32 sceDdrdbSigvry	(	u8 *	pPubKey,
		u8 *	pData,
		u8 *	pSig
	)

Verify if the provided signature is valid for the specified data given the public key.

Note

The ECDSA algorithm is used to verify a signature.

Parameters

pPubKey	The public key used for validating the (data,signature) pair. Size has to be KIRK_ECDSA_PUBLIC_KEY_LEN.
pData	Pointer to data the signature has to be verified for. Data length: KIRK_ECDSA_SRC_DATA_LEN
pSig	Pointer to the signature to verify. Signature length: KIRK_ECDSA_SIG_LEN

Returns

0 on success, otherwise < 0.

sceDdrdbCertvry()

s32 sceDdrdbCertvry

(

u8 *

pCert

)

Verify a certificate.

Parameters

pCert

Pointer to the certificate to verify. Certificate length: KIRK_CERT_LEN.

Returns

0 on success, otherwise < 0.

sceDdrdbSiggen()

s32 sceDdrdbSiggen	(	u8 *	pPrivKey,
		u8 *	pSrcData,
		u8 *	pSig
	)

Generate a valid signature for the specified data using the specified private key.

Note

The ECDSA algorithm is used to generate a signature.

Parameters

pPrivKey	Pointer to the private key used to generate the signature. CONFIRM: The key has to be AES encrypted before.
pData	Pointer to data a signature has to be computed for. Data length: KIRK_ECDSA_SRC_DATA_LEN
pSig	Pointer to a buffer receiving the signature. Signature length: KIRK_ECDSA_SIG_LEN

Returns

0 on success, otherwise < 0.

sceDdrdbPrngen()

s32 sceDdrdbPrngen

(

u8 *

pDstData

)

Generate a KIRK_PRN_LEN large pseudorandom number (PRN).

Note

The seed is automatically set by the system software.

Parameters

pDstData

Pointer to buffer receiving the PRN. Size has to be KIRK_PRN_LEN.

Returns

0 on success, otherwise < 0.

sceDdrdb_F013F8BF()

s32 sceDdrdb_F013F8BF	(	u8 *	pData,
		u8 *	pSig
	)

Verify if the provided signature is valid for the specified data. The public key
is provided by the system software.

Note

The ECDSA algorithm is used to verify a signature.

Parameters

pData	Pointer to data the signature has to be verified for. Data length: KIRK_ECDSA_SRC_DATA_LEN.
pSig	Pointer to the signature to verify. Signature length: KIRK_ECDSA_SIG_LEN.

Returns

0 on success, otherwise < 0.
