kdf of crypto module

函数说明

◆ CRYPT_EAL_KdfCopyCtx()

int32_t CRYPT_EAL_KdfCopyCtx	(	CRYPT_EAL_KdfCtx *	to,
		const CRYPT_EAL_KdfCtx *	from )

Copy the context of kdf Note: When using HKDF for key derivation in CRYPT_KDF_HKDF_MODE_EXTRACT mode, need set the new context's extended length use CRYPT_PARAM_KDF_EXLEN.

参数

from	[IN] kdf context
to	[OUT] kdf context

◆ CRYPT_EAL_KdfDeInitCtx()

int32_t CRYPT_EAL_KdfDeInitCtx ( CRYPT_EAL_KdfCtx * ctx )

Deinitialize the context of kdf

参数

ctx	[IN] kdf context

返回值

CRYPT_SUCCESS For other error codes, see crypt_errno.h.

◆ CRYPT_EAL_KdfDerive()

int32_t CRYPT_EAL_KdfDerive	(	CRYPT_EAL_KdfCtx *	ctx,
		uint8_t *	key,
		uint32_t	keyLen )

Derived key

参数

ctx	[IN] kdf context
key	[OUT] Derived key
keyLen	[IN] Specify the key derivation length

返回值

CRYPT_SUCCESS For other error codes, see crypt_errno.h.

◆ CRYPT_EAL_KdfDupCtx()

CRYPT_EAL_KdfCtx * CRYPT_EAL_KdfDupCtx ( const CRYPT_EAL_KdfCtx * from )
